PeachTree Nova 300

PeachTree Nova 300

PeachTree Nova 300 

Integrated amp (2022)  SOLD 
450 WPC  (mint, warranty, original box)

Essentially still new, this Peachtree Nova 300 was purchased by Davidson Audio primarily to test a new loudspeaker design.  It comes with the factory remote, original box, documentation and the factory warranty good through 2025. 

Among its many features, we tend to focus on the moving magnet phono input and a HIGH OUTPUT discrete headphone amplifier.
Versatile and very powerful, the Nova 300 pumps out an astounding 450 watts per channel into 4 ohms and a minimum 300 watts per channel into 8 ohms.  Pick out most any loudspeaker model on the planet and the Nova 300 will drive them with ease. 

The cabinet design is slim with radius corners and a piano gloss black finish.  It almost defies belief that Peachtree could design an integrated amp that powerful yet present it such a relatively small cabinet that can fit just about anywhere and still look so beautiful.  At about 14" wide x 14" deep x 4" high and only 17 lbs. it's an audiophile's dream unit to anchor ANY system you can imagine.

At first glance, the available inputs on the rear can appear overwhelming but, after realizing how creative and accommodating they really are, it can handle all the usual components with ease and simplicity.  If you are an Apple user, Peachtree has included built-in links for more ease of use.  (sorry, Android people).

The well designed remote is a breeze for operation of the unit. 

Built-in protection means you can never accidentally suffer any speaker overloads either.
Remember something important, as already mentioned, the factory warranty is still in effect through 2025.

About Peachtree...
Peachtree Audio introduced its first product in 2007: the groundbreaking Decco. An integrated amplifier. Audio industry veterans Jim Spainhour and David Solomon recognized that music listeners were moving toward computerized audio, but the business-as-usual industry wasn't adapting. Unwilling to compromise audio quality for the convenience of digital files, they devised a new kind of integrated amplifier. This would be an amplifier with a built-in digital-to-analog converter, capable of extracting maximum fidelity from computer music files and from digital music streamers like Sonos and Apple TV. Thus was born the iconic Decco - it debuted to critical acclaim and laid the foundation for Peachtree Audio's reputation for innovation and great sound at rock-bottom prices. The Decco was the world's first integrated amplifier with a USB input, allowing its built-in digital-to-analog converter to process music files directly from a computer.


Marantz 2270

Marantz 2270

Marantz 2270   

(1976) 70 WPC    SOLD

This Marantz 2270 was obtained locally and had been in storage for many years.  It has been extensively restored as detailed below. The cosmetic condition is excellent.  It comes with the vinyl-on-metal case.

Prior to the extensive restoration, it was initially on the bench for our usual pots/switches cleaning, testing, etc.   After that initial basic servicing, it was then completely and professionally restored.  That included all new Nichicon electrolytic capacitors on the tone board, phono board, power supply and main power amp.  This service includes detailed testing and performance hard copy reports, updated parts list, updated specs (comparing the original specs vs the updated specs) along with a few before and after photos. The DC offset and idle current are also in perfect spec.  A copy of these reports along with all the old caps and parts will be included.

The completed service included:
 ~Filter caps C007, 008 replaced with upgraded 10,000uf 100v Capacitors
~All electrolytic capacitors were replaced on the P700 power amp, P400 phono amp, P500 tone amp, P550 muting circuit, main filter L/R and P800 power board. (a total of 38 electrolytics plus the 2 main filter caps).  
~A number of Mylar signal capacitors were replaced with WIMA Film Capacitors on the Phono and Tone amp
~AC cord replaced with a standard length cord. 
~Left channel amplifier bias transistor H760  was repaired to correct over / non adjustable bias setting 
~Damaged Dubbing out jack replaced 
~Dial and meter lamps were replaced with warm white LED.
~Vellum diffuser replaced with high quality 220 gpm vellum
~Pre-amp/amp jumpers replaced with a high grade custom alloy RF quality jumper

After completion of the recap/restoration, it was then on the bench for a third time to repeat the initial pots/switches and final testing.  This Marantz 2270, for all practical purposes, is right up there (specs-wise) as it was when first released from the factory.

NOTE: The majority of the labor intensive service work was performed in April 2024 by one of our associate technicians who, just prior to his recent retirement, was a long-time Marantz senior factory technician in Chatsworth California. It's pretty well known that the 2270 units had a rather long production time from 1971 to 1976.   Marantz made small changes in the outer design, knobs, speaker terminals, and different front panels in the early days.  Inside, there were some mods to the power amps and circuitry. 

Although the Marantz 2270 is rated at 70 watts per channel into both 8 and 4 ohms, one of the more interesting test results on this particular recapped unit shows the rated power output is actually 81 watts per channel into 8 ohms and 127 watts per channel into 4 ohms before clipping. 

Additional services include all new custom "frosted white" LEDs.  Unlike typical LEDs, these lamps are specially designed to cast a smooth backlight to accentuate the stunning blue glow across the front glass that also includes the meters.  All of the other function lamps are in perfect working order.

There is plenty of chatter online about the Marantz 2270 for those who wish to do a deeper dive into the particulars.

Test/bench essential specs after recap:
~Power output:  81.2 watts per channel into 8 ohms
                        127.7 watts per channel into 4 ohms
~THD:  0.25%
~Frequency response:  20Hz -20 kHz
~Dimensions: 18.25"W x 16"D x 7.25"H (including case)
~Weight: 40 lbs
~Original MSRP (Mid 70'S):  $600

Marantz 2220B

Marantz 2220B

Marantz 2220B 

('75-'77)  20 WPC  $1100

In absolutely pristine cosmetic condition and fully operational, this beautiful Marantz 2220B stereo receiver was the replacement for the earlier Marantz 2220.  It was disassembled for servicing that included a partial recap on the phono board.  All pots and switches were checked and deoxit was applied.  All new fuse lamps were installed. Bench tested to assure that every function is now in perfect working order.  Prior to the bench servicing, we removed the original factory protective faceplate cover.
(NOTE: All Marantz units of that era were shipped with plastic faceplate protectors. It's very rare to find a unit with the protective plastic still in place.)  Because it still had that cover, the faceplate is in the same new condition as when it was shipped.  We will include the cover to the next owner. 

The factory WC-22 walnut case is also pristine.   Honestly, there's not a mark or scratch to be found anywhere on this receiver.  It's truly one of the best well-kept Marantz units we've seen to date.

From the "best" era of Marantz during the 70's, the 2220B has that very recognizable and popular design: heavy silver aluminum faceplate with blackout dial and the beautiful blue glow of the dial and meter.  Of course the gyro tuning wheel is instantly recognized as one of the best known features about Marantz.   Selling for about $300 in 1974, these receivers are known for having long and productive lives when well taken care of...just like this one!

Of the two similar (but different) Marantz models (2220 vs 2220B) the 2220B sold like hotcakes and is generally more popular as it has a well deserved reputation of being able to put out close to double it's rated watts.  This power difference over the 2220 is most likely due to the direct coupled outputs on the "B" versus the capacitively coupled outputs on the other.  Cosmetically, besides the faceplate, the major difference is the 2220B has a slider control for balance instead of a knob.

Essentially, the 2220B punches out more than its very conservative rating of 20 watts per channel.  For those who realize that, in some cases (depending on your REAL needs), you just don't need a ton of power, preferably when driving high quality efficient speakers....especially if the amp section is as good as this one is.  Because this receiver is relatively easy to service, everything about this Marantz 2220B, inside and out,  was put together with simplicity in design and function.

Basic specs:
Power: 20 watts per channel into 4 & 8 ohms 
Frequency response: 10Hz to 50kHz
THD: 0.9%
Dimensions: 18.25"W x 7"H x 15.25"D (including case)
Weight : 35 lbs. (including case)

Marantz 3200

Marantz 3200

Marantz 3200

preamp ('73-'76)   NFS display only
Properly cleaned, professionally restored and fully tested, this Marantz 3200 Control Center (preamp) is a rare and lovely example of the available Marantz technology during the early-to-mid 70's.  
The 3200 was given our usual thorough inspection, cleaning, testing, etc but a big part of the bench servicing included a recap of the always important phono stage (the old tantalum capacitors were removed and replaced with modern film caps).

The simple yet unmistakable Marantz 3200 front facia design has just the right amount of knobs and controls.  There are no redundant or obsolete controls; every function is readily usable.  It will mate perfectly with almost any high quality stereo amp as part of a "typical" vintage stereo system. 

Among its features, the 3200 has 2 phono inputs along with the tuner and aux inputs.   Perhaps its best feature is revealed if you look at the 3200 as essentially two totally separate units (a preamp and a speaker selector) on one common chassis.  Simply put, the speaker wire outputs of the amp connect to the speaker wire inputs on the 3200.  This now gives the 3200 complete control of up to two pairs of speakers.

Marantz; a different perspective...
More than any other person, Saul Marantz defined premium home entertainment. Driven by his passion for music and his accomplishments as a classical guitarist – accomplishments that led to a close friendship with Andres Segovia – he was never satisfied with the “hi fi” equipment of his day. So he built better; first in his basement, later in a factory. His talent for industrial design and his ability to infuse talented engineers like Sidney Smith and others with his vision resulted in legendary products: The Model 7 preamplifier. The Model 8 and, soon after, the 8B power amplifier. And insured that his company would remain a premiere name in the industry he helped establish.

In the '60’s. Marantz made multiple significant moves. NASA found the Model 9 stable enough to be used in tracking stations around the world as part of the famous Apollo space program. Marantz also decided to relocate to California within this decade. Most notably, in 1964, Marantz was acquired by SuperScope.

Fueled by financial backing, innovative product development and additional production facilities in Japan, Marantz experienced excessive growth and expansion in the 1970’s. It was also the decade of the famous “2200” receiver, which turned out to become the most successful receiver line in consumer electronics history.

To Marantz, perfect specifications and technical accomplishment count for nothing unless a product can unlock the power, the excitement, and the emotion of music. Their heritage of technical excellence means they can create components with the ability to communicate the scale, timbre, pitch, and dynamics—in fact, the very essence—of a recording. Every Marantz component is technically and cosmetically designed to complement the lifestyle of the listener.

About Proceed (Madrigal Audio Laboratories)...Madrigal Audio Laboratories was a producer of high-end audio and video equipment that closed their doors in 2002.  During the course of their operation they designed a series of high-performance audio and video components under the brands: Audioaccess, Mark Levinson, Proceed, Madrigal, Imaging, and Revel.

From Wikipedia:

Madrigal Audio Laboratories was founded in 1984 by Sanford Berlin (1927 – March 11, 2008), when he took over the Hi-end audio-company Mark Levinson.  Further brands of Madrigal were Audioaccess, Proceed, Madrigal, Imaging. In 1997 the subsidiary Revel Audio for high quality loudspeakers was founded.

In 1986 Madrigal went to court with Mark Levinson. One result was that Levinson was not allowed to use his name as a trade anymore.

In 1990 Madrigal offered a high value CD Player branded as Proceed. In 1996 multi-channel amplifiers were branded also as Proceed.  A further product were state of the art video-projectors.  The company closed in 2002 and became part of the Harman International Group.


Kenwood KS-4000R

receiver ('80-'84) 14 WPC  SOLD

Kenwood KR-8010

Kenwood KR-8010

Kenwood KR-8010  

('79-'80)  125 WPC   $750  (includes vu meters shown)

In excellent cosmetic condition, this Kenwood KR-8010 is typical of the technical and aesthetic works of art coming out of Japan in the late 70's.

The brushed extruded aluminum front panels, diamond-machined knobs, analog meters, nice "slide-rule" dials and the backlit power meters are just a few of the attractions on this massive Kenwood unit. 
(NOTE: As shown above in one of the photos, the unit comes with the original chrome rack handles included at no charge; easy on, easy off)

At the time of its release in early 1979, this Kenwood KR-8010 was second only to the top of the line KR-9600.  The KR-8010 pushes out a conservative 125 watts per channel (8 Ohms) and 135 watts per channel into 4 ohms.

It has five analog inputs (including two phono) and three-band tone controls.  All functions work perfectly except for the tuner.  A separate (free) tuner is available and can be connected through one of the tape inputs.

Besides its massive transformer and overall excellent build quality, it should be noted that the KR-8010 uses the exact same output transistors as the Pioneer SX-1250 receiver and the "holy grail" Concept 16.5 receiver.

Basic specs:
Frequency response: 5Hz to 100kHz
Total harmonic distortion: 0.03%
Speaker load impedance: 4 ohms (minimum)
Dimensions: 22.5:W x 6.6"H x 18"D
Weight: 41 lbs

Kenwood KA-601 (meters not included)

Kenwood KA-601 (meters not included)

Kenwood KA-601

integrated amp  90 WPC @ 4 / 60 WPC @ 8  $500

In excellent cosmetic and working condition, this Kenwood KA-601 integrated amplifier is rated at a minimum 60 watts per channel (8-ohms) and close to 90 WPC (4 ohms)  @ 20 to 20,000 Hz, with less than 0.02% THD.  Many bench tests of the 601 prove the THD was indeed, even lower than claimed by Kenwood. 

With separate (dual) power supplies in the KA-601 for its two channels, they are fed by a common power transformer and the power-amp sections are *direct-coupled.  It's a big beefy unit with a "service friendly" build quality.

The KA-601 made a big splash in the late 70's because it was so affordable which made it easier to buy a world class unit with extremely low THD usually found on much more expensive amps.  The well laid out front silver faceplate is dominated by the large, beefy volume-control knob near its center with a 32 position step attenuator whose detents are so light that you're hardly aware of their presence. 

In order to keep the cost down on the KA-601, Kenwood decided there would be no vu-meters meters and no chrome knobs or switches. 

The bass and treble tone controls are each 11 position step controls, and the balance control is lightly detented at its center. Curiously, there's a mysterious switch labeled "DC Coupled on/off" which, in reality, is a fancy name for a "rumble" filter.  Finally, there are also level switches for tone defeat, subsonic and high filters, and a 20-dB audio attenuator.  On the back are outputs for 2 pairs of speakers, inputs for two turntables, two tape loops, tuner and AUX.

Basic specs KA-601:

Power output: 60 watts per channel into 8 ohms
                         90 watts per channel into 4 ohms
Total harmonic distortion: 0.02%
Dimensions: 17.3"W x 6"H x 16"D
Weight: 26 lbs

About "direct-coupled"...
The development of the direct-coupled output stage first appeared around 1971 when a new series of Panasonic-branded receivers (about a year before they came up with their “Technics” brand marketing angle for their high-fidelity division) were advertised as having direct-coupled amplifier sections, resulting in flatter frequency response into the lowest bass range, at full power and lower distortion than had previously been possible with traditional capacitor-coupled designs. Pioneer, Kenwood and many others soon followed suit and the availability of truly full-range, low distortion amplifiers made really satisfying audio reproduction a new twist in the world of HiFi.

Marantz, in particular, stressed that DC coupling was used between the amplifier's output transistors and the loudspeaker load with no transformers or capacitors to get in the way. This was common in the better classes of equipment of the day, but still not universal. DC coupling helps maintain the amp's damping factor (eg, its ability to control and position a woofer cone accurately) at low frequencies. This is not the case with transformer or capacitor coupling and, provided the amp is correctly designed and its power supply can cope, DC coupling will typically result in tighter and cleaner bass, especially at high listening levels.

About Kenwood (Trio)...
Established in 1946 as the Kasuga Radio Co. Ltd. in Komagane City, Japan, in 1960 the company was renamed Trio Corporation. In 1963 the first overseas office was founded in Los Angeles.

In the early 1960s, Trio's products were rebranded by the Lafayette Radio Co with a focus on CB radio.

An importer of Japanese-made electronics Radio Shack (Realistic, Tandy Corp) was A&A Trading Co., and a bilingual Japanese-speaking manager from there established a company that would be the exclusive importer of Trio products.

The name Kenwood was invented by Kasuga as being the combination of "Ken", a name common to Japan and North America that had been tested and proven acceptable to American consumers in the name of Kenmore appliance (Sears) \, and "Wood", referring to the durable substance as well as suggesting a relation to Hollywood.  The brand recognition of Kenwood eventually surpassed that of Trio's, and in 1986 Trio bought Kenwood and renamed itself Kenwood.  Eventually, Kenwood merged with JVC in 2008 as JVC/Kenwood.
