Jolida JD1000BRC Integrated Tube Amp
Meet Jolida's latest high-performance vacuum tube components. These components offer an unusual combination of the new and the old in audio technology: digital convenience and tube analog sound. The Design Challenge: Build a stereo tube amplifier with a sound quality that equals or exceeds the best in high end audio equipment. Included were two major criteria, make sure designs are reliable and can be sold at value prices. The Engineering Result: An integrated stereo tube amplifier that can be hooked up directly to a CD player and two speakers. The Sound: High end audio tube performance at a value price. 100 watts per channel, hi-performance sound, this is characteristic of Vacuum Tube Technology in the JD 1000BRC. Clear, robust bass with smooth highs in a value priced package. Remote volume control and an EZ-Biasing system make the operation and the maintenance of the JD 1000BRC a simple matter.
