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 very young age. He applied
his talent to produce numerous innovative high fidelity designs since the 1970s. He is known for designing the
Phase Linear 700, at 350 W per channel, the most powerful consumer audio amplifier available in 1972. He went
on to found the Carver Corporation in 1979 and Sunfire in 1994.
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 took him up on 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).
In 1985, Stereophile magazine challenged Bob to copy a Conrad-Johnson Premier Five (the make and model was
not named in the challenge but revealed later) amplifier at their offices in New Mexico within 48 hours. The Conrad
Johnson amplifier was one of the most highly regarded amplifiers of its day, costing in excess of $12,000.
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, successfully copied the sound of the
target amplifier and won the challenge. The Stereophile employees failed to pass a single blind test with their own
equipment, and in their own listening room. He marketed “t” versions of his amplifiers incorporating the sound of
the Mark Levinson and Conrad Johnson designs which caused him some criticism by those who failed to
understand the true nature of the challenge — that it was possible to duplicate an audio amplifier's sound in two
completely dissimilar designs. In light of this criticism, Bob Carver went on to design the Silver Seven, the most
expensive and esoteric conventional amplifier up to that time and duplicated its sound in his M 4.0t and later
models which sold for some 1/40th the price (around $600–$1500).
This also started Carver's departure from the M-series amplifier to the more robust and current-pushing TFM
series amplifiers. The TFM amplifiers were designed specifically to drive the demanding load of the Amazing
ribbon loudspeakers. The apex of Carver's amplifier line was the Lightstar, which is now a collectors' item. Only
approximately 100 of the amplifiers were made. The original Lightstar amplifier, called the Lightstar Reference,
featured a dual-monoblock design, with separate power cords for each channel. A later version, called the
Lightstar 2.0, featured one power cord & other cost-saving measures to shave approximately $1800 off the retail
price. The two are reported to be sonically identical.
Carver has used some names which have clearly defined technical meanings so oddly unrelated to his products'
actual design and function as to be merely amusing rather than deceptive.
