Preamplificador AUDIO RESEARCH LS22. Incredible “pure valve” preamp from Audio Research. The last of these features. The following were mixed.

The best Audio Research preamplifier up to that moment, even than the LS2 or the SP11 in the classification of the prestigious HI-CRITICS magazine

Totally recap.

New Tesla NOS tubes much more musical than the originals. I have the originals, too. I have the originals valves too and can be send with the preamp and listen to compare.

HIFI TUNING supreme 3 fuse.

Original packaging (double box).

It is not the version with remote control.

I am selling because I pass Krell system using CAST cable
