Tube stereo line stage.
|
If you appreciate the natural-sounding reproduction of music made possible by vacuum-tube technology, but were afraid of the hassles and the prohibitive pricehave we got news for you. Audio Research, the 25- year leader in vacuum-tube technology dedicated to music reproduction, has made a vacuum-tube music system more affordable than ever. It's the New LS7 stereo line preamplifier and VT60 stereo power amplifier, both featuring new, all-tube circuits that deliver rich, satisfying sound and world-renowned Audio Research construction. Two down-to-earth audio components that are capable of truly out-of-this-world performance. |
