Carver TD-1440

stereo cassette deck (1992)  $250

Originally part of a rack system, this fully functioning Carver TD-1440 is a stereo cassette deck with Dolby B/C and HX-Pro noise reduction.  It was introduced by Carver in '92 with a rather steep $380 price tag.  We added a mahogany veneer cover over the black metal case and the faceplate is pristine.  We do not have the remote but they may be available online.


The main features of the Carver TD-1440 are:, analog 3 digit tape counter, automatic tape type selection with support for normal, chrome and metal tapes.

Typical front loading cassette deck with the cassette compartiment located on the left side of the deck. Tape eject is operated mechanically and the cassette needs to be placed with the side to be played facing forward in the cassette well.

As the closeup photo (above) of the meters used on the TD-1440 shows, they are very cool...a very different design of analog needle VU reading meters.  They also have built in red LEDs to indicate peak signals.  Full-logic transport controls used on the TD-1440 let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the TD-1440 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. The Dolby HX PRO system provides precise bias control during recording to reduce distortion and improve linearity in the high-frequency range, the result is recorded sound that is highly faithful to the original. To further maintain recording accuracy, the TD-1440 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the TD-1440 can be switched on to prevent the standard 19kHz FM pilot signal from interfering with the noise reduction system.

Connection to other audio components for playback is typically achieved with the included RCA cables.

About Carver...

Robert W. (Bob) Carver is an American designer of audio equipment based in the Pacific Northwest.

Educated as a physicist and engineer, he found an interest in audio equipment at a young age. He applied his talent to produce numerous innovative high fidelity designs since the 70's.  He is known for designing the Phase Linear 700, at 350 watts per channel the most powerful consumer audio amp available in 1972. He went on to found the Carver Corporation in 1979, Sunfire in 1994, and the Bob Carver LLC in 2011 which was sold to Jade Design in June, 2013.  However, in December 2013, Bob Carver and Jade Design parted ways.

Carver caused a stir in the industry in the mid-1980s when he challenged two high-end audio magazines to give him any audio amplifier at any price, and he’d duplicate its sound in one of his lower cost (and usually much more powerful) designs. Two magazines accepted the challenge.  First, The Audio Critic chose a Mark Levinson ML-2 which Bob acoustically copied (transfer function duplication) and sold as his M1.5t amplifier (the “t” stood for transfer function modified).  Then, in 1985, Stereophile magazine challenged Bob to copy a Conrad-Johnson Premier Four (the make and model was not named then, but revealed later) amplifier at their offices in New Mexico within 48 hours. The Conrad Johnson amplifiers were one of the most highly regarded amplifiers of the day, costing in excess of $6,000 a pair.

Of note that in both cases, the challenging amplifier could only be treated as a "black box" and could not even have its lid removed. Nevertheless, Carver, using null difference testing, (null difference testing consists of driving two different amps with identical signal sources and exact levels, but out of phase by exactly 180 degrees. If the amplifiers were 100% identical, no sound would be heard. If sound was heard, the audio amps had different properties). Bob Carver used "distortion pots" to introduce amplifier characteristics, fine-tuned to null-out any sound differences. His "motel-room" modified amplifier sound was so similar, Stereophile Magazine editors could not tell the difference between his amplifier and one costing more than $6,000. This amplifier was marketed as the M1.0t for about $400.00. Bob Carver may have single-handedly debunked any number of theories about sound quality by using physics, blind and double-blind testing and unbiased measurements (such as "gold-plated speaker wires sound better than copper wires", etc.). Carver successfully copied the sound of the target amplifier and won the challenge. 

Of course there's a lot more to the history but the magazine challenges opened the door to him being able to "carve" his name in the audiophile community around the world.

NAD C-515BEE 

CD player w/remote (2008)  SOLD

When first introduced, the NAD C 515BEE was NAD's most affordable CD player listing at $300 in 2008.Originally it was designed to match the NAD C316BEE integrated amp. 

On the NAD's front panel, from left to right, are a power button, the disc tray, a modestly lit vacuum-fluorescent display, and two rows of three buttons each: on top, Play, Pause, and Stop; below those are Open/Close, and forward and backward Skip/Scan. So smooth and quiet is the NAD's tray that inserting and removing CDs is always a pleasure.

On the rear panel are an analog output, coaxial and optical digital outputs, and a simple AC power cord. The overall appearance is typical styling from NAD...handsome and serene.

The included remote control (small and light) allows the user to do all sorts of fun stuff: program tracks, repeat a single track or a section within a track  and adjust the display's brightness. 
Surprisingly smart, the C 515BEE can play MP3- and WMA-formatted recordings burned to CD-R or CD-RW discs.

Dimensions: 17 1/8" W x 2 3/8" H x 9½" D Weight: 7.75 lbs.


About NAD (New Acoustic Dimension)...

NAD Electronics is a brand name of an electronics firm whose products include home HiFi amplifiers and related components.  The company was founded in London, England, in 1972 by Dr. Martin L. Borish, an electrical engineer with a PhD in physics. Its most famous product is the late-1970s NAD 3020 an integrated amp designed by Bjørn Erik Edvardsen, which was highly regarded by various magazines in Britain.  NAD's philosophy is to include only genuinely useful features for aesthetically understated designs when compared to other competitors' products. NAD was one of the first audio manufacturers to outsource the manufacturing of its products to electronics factories in east Asia.  NAD was acquired by the Danish firm AudioNord in 1991 and subsequently sold in 1999 to the Lenbrook Group of Pickering, Ontario, Canada
