design for over one year, the white knuckles screaming amp, outperforms
amps priced at 5 times the cost of the Bob Carver Crimson 275! Very
closely the Crimson 275 performs next to our 350 series monoblocks which
sell for $9,500 pair!
Bob Carver holds more audio patents than 31 Flavors Ice Creamery.
Bob’s unique DC restorer circuit offers much lower distortion – extended tube and amplifier life.
Totally seriously cool!

is a meter on the front of the amplifier which indicates the health of
the tubes — get a bad reading, get free tubes! Aside from the extended
circuit and tube life, it’s the sonics that blew us away. One of the
reasons for this is our proprietary use of two separate feedback loops.
One, typical of what you’ll find in many fine amplifiers, ensures
stability and linearity. But the other is quite fascinating.
An amplifier that actually listens to the room.
loudspeakers generate voltage as they play. It’s generated from the
driver movement necessary to reproduce music but also all loudspeakers
technically “listen” to the room.
are electric motors. Electric motors all kick voltage back to the power
source whether it’s a loudspeaker, a refrigerator or an electric
drill. Manufacturers of line conditioners have a point. Your
refrigerator motor not only adds noise to the AC line, they actually
send electricity back through the wall outlet. We call this Back-EMF.
a tube type amplifier, when back EMF appears at the output terminals,
to the loudspeaker the output transformer’s secondary becomes a primary!
The back EMF enters the amplifier through the transformer and affects
frequency response downstream. With ordinary tube type amplifiers,
speaker matching becomes critical. Our amplifiers are load-invariant.
Through decades of experimentation and some pretty heavy mathematics,
Bob Carver has been able to use the Back-EMF to increase efficiency in
the mighty SunFire subwoofers, and to improve the soundstage and
openness of his full range amplifiers.
done in a unique fashion, and, as in the case of our extended tube life,
unique to our products. The amplifiers listen to the room through the
loudspeakers and preserve a large soundstage. It took literally decades
to get the circuit right without creating artificial coloration. If
you’re concerned about naturalness, consider that Harry Pearson, the
founder of Absolute Sound Magazine, noticed this phenomenon, pointed out
to Bob (who already knew about it) and kept our Silver Seven amplifiers
as his personal reference for years. Dick Olsher from Stereophile
Magazine called this series the most important tube amplifiers in
