The LS25 vacuum tube stereo line preamplifier offers sonic performance, functional flexibility and value second only to the world-renowned Reference One preamplifier. It is unprecedented measured by any performance criteria at its price.
Built much like a compact Ref One. With Infinicaps.
Audio Research LS-25 Tube Stereo preamp.
Line stage only - no phono.
This incredible ARC preamp is the one of best I have had in my system and I have had many...
Dynamic, spacious, detailed- it has it all and more!
Super-clean. New tube set last month. One Owner!
Ships in nice clean original box with remote control and original manual and receipt for new tubes.
Cosmetic: Excellent. Low hours as evidenced from still supple rubber tube rings.
Function: Works very well. One minor caveat: When volume is cranked way up to 3:00 on analog clock position (see pic) , the left channel sometimes has some noise/volume drop.
Per inquiry to ARC this is a minor issue with the upper stage of the 2-stage electronic volume control.
The original owner never even noticed this as under actual usage conditions, this is ear-bleed level. At any normal listening level, the volume control sounds fine. I have discounted the price to reflect this issue but the new owner may or may not wish to address it.
