What Makes SAS Audio Tube Preamplifiers Different? | 10A tube Preamplifier


audio preamplifiersClick 11A


Martin DeWulf, publisher of Bound for Sound, Issue #178 Review: "I liked this preamp enough to purchase it. Because of its flexibility, unfailingly honest approach to the music and its organic honesty, I bought it. But it's more than a reviewer's tool. It's a music lover's companion as it is able to express the finer, the more subtle aspects of a performance, without resorting to proven audio gimmickry. It took an industry outsider of sorts to put into place a different set of sonic priorities, one that got us closer to the music and away from the bottom line."

"Direct comparisons to my old friend, the Symfonia Opus 8 ($7,000), revealed the SAS to be cleaner, more transparent and more organic through the midrange... Remember, it was the Symfonia Opus 8 that went toe-to-toe with the exalted CTC Blowtorch ($15,000.)." (The CTC Blowtorch team included John Curl, Bob Crump, and Carl Thompson.)

Martin DeWulf, publisher of Bound for Sound, Issue #199/200, March 2010: : McCormack VRE-1 (dealer 14 grand) compared to the SAS Audio 11A.

Reviewer Richard Weiner has also purchased the 11A line preamplifier as his reference.


11A Vacuum Tube Preamplifier, Reviews, Features, Specifications, Shopping Cart

Welcome to SAS Audio Labs. The reference 11A line preamplifier is the culmination of decades of research and development. Whether orchestra, opera, jazz, or rock, the 11A brings out the emotions, the realism of the event. This means no remote to tarnish the music. The 11A is making a huge statement, winning out over 46 brands and models costing up to 15 grand. Besides using my unique design, each custom ordered 11A is carefully hand assembled for near perfect reliability, so no breakdowns to worry about, now or in the future.
