Bob Carver Releases 20 Watt Stereo Vacuum Tube Amplifier

Lexington, Kentucky June 18, 2012 - Bob Carver LLC, a specialist in the design and manufactuing of audiophile products just announced a new 20 Watt Stereo Amplifier called the Black Magic 20.

"This amplifier has surprised me with its large, beautiful soundstage.  It has brought music to life with a reach and a beauty this is difficult to describe.  It fills the room and gives each individual instrument an exact location inside the stereo acoustic soundscape.  You will be stunned by the detailed sweetness this small, unpretentious amplifier can deliver" says Bob Carver.

"The VTA20S represents Bob's latest and greatest thinking on vacuum tube amplifier designs.  This amplifier has many deluxe features not normally found in lower cost units" says Bob Farinelli.

A screen voltage regulator and DC restoration circuit minimizes crossover distortion and output tube power dissipation.  The 1.5 ohm output impedence coupled with current and voltage feedback loops also allow the amplifier to listen to the room via acoutic feedback from the speakers.

"The room-to-speaker-to-amplifier interaction delivers a huge acoustic space and allows us to believe the performance could have existed in another time and in another place.  It sounds so beautiful!" says Bob Carver.

The new stereo amplifier is conservatively rated at 20 WRMS in 2 channel stereo mode or 40 WRMS when used in single channel mono mode.  The amplifier features auto biasing and low idle current greatly increasing EL84M output tube life.

"True audiophiles know the measure of an amplifier's performance is not found on the test bench but simply how pleasurable and realistic it sounds in their living rooms.  After 40 years of learning and building upon the designs of some of the most famous amplifiers ever conceived, Bob has applied his magic formula to the Black Magic 20.  Once again, other products found in this price range simply do not compare in overall sonic performance" says Bob Farinelli.
