Bob Carver Crimson 275 Stereo Tube Amplifier

Selling this amp as I'm making some adjustments to my system. I would characterize this as having a very smooth and clean sound, driving my Zu Audio speakers with a lot of authority and depth.   
Used for about 6 months, in excellent condition, and comes from a smoke free environment.

From Bob Carver:   
The Crimson 275 uses KT120 output tubes that run thru Bob's unique DC restorer circuit. This allow them to run cool and extend tube life. You can actually touch the tubes during play and they are not hot. The amp and tubes come with a 5 year factory warranty and the tubes should last a lifetime. 

The variable bias circuit allows you to fine tune the sonic signature and make the amp sound warmer like a classic tube amp or add detail like a more contemporary design. Set from the factory the 275 sound amazingly close to the large 350 watt mono's but with only 1/4 of their power at about 30% of their cost.

Bob’s unique DC Restorer circuit makes the amp much more efficient than conventional allowing the use of hi efficient smaller output transformers. Advantages are that it runs much cooler than normal tube amps, weighs less and the tubes should last forever. Finally, by using smaller output transformers the cost and size is also lowered. Compare this amp to any under $5,000.00 competitor.

Another significant feature of Bob’s design is its ability to “listen to the room,” sometimes referred to as the ‘speaker-microphone effect.’ Facilitated by a special current feedback loop, it allows the amplifier to ‘hear’ the room’s reverb, along with its unique sonic signature. Each room plays its own tune, and this amp uses the speaker as a microphone by using the speaker in reverse (the theorem of reciprocity) to ‘listen to the room,’ thereby allowing a portion of the room acoustic to be expressed through the main speakers. Think of it this way, the room becomes an integral part of the music in a way no other amplifier allows. The sound is more majestic, more realistic, and the soundstage is larger and more compelling than it would be without this unique ability.
