Audio Research LS-17 SE

Fully balanced XLR connections as well as single-ended for other components combined with tube sound in a quiet, dynamic preamp. On-line forums report the SE update to this venerable model was apparently quite significant.

This preamp looks and sounds new--especially since I've upgraded tubes to the Electro-Harmonic 6H30Pi Gold Pin tubes. Please see photo for their test readings; these were "ARC Select/Cyro Treated" (for long life), the best tube of this category. I will include the original tubes if the buyer desires. The new tubes have approx. 15 hours on them so are still breaking in. My decision for selling is I decided to finally part with my favorite Mac MC-150 amp (now sold) so I can indulge in vintage audio.

I'm updating the condition of this preamp in accordance with its appearance to several objective viewers. This preamp looks bright and new, and when I changed the tubes the sockets were so tight I suspect I replaced the factory originals. Brushed aluminum finish is inherently variable, part of its charm. Looks and operates as new. See photos. Please note my ratings; I would not misrepresent any item.

Includes manual, power cord and remote. Ships in original box and packaging. From a non-smoking home. Economy shipping to lower 48. Preference given to well-reviewed Audiogoners. Thanks for looking!
