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.
Multiple Inputs: Front mounted selector switch-Tuner, DVD, CD, and Aux. (for Tuner, TV, VCR or (Computer)
