10A triode preamp

Bound for Sound, Issue #163 SAS Audio 10A Triode Preamp is one of only 3 listed in "Exceptional Merit" catagory. "I expecially feel that way about the SAS 10A, a tube unit of moderate expense that simply stomps a mud hole in just about every active unit made - regardless of price."

Rich Weiner: "The SAS 10A is the most musically truthful preamp I'm aware of, and I will expand that statement by listing some of the line stages I've had in my otherwise very stable system: Herron VTSP-1, VAC CPA III, VAC Standard LE, Audio Research 3A, ARC 8, ARC 10, Mark Levinson ML-1, Levinson ML-7, Levinson ML-10A, Original Aronov PS-100 and Musical Concepts modification, Nagra PL-P, Beveridge RM-1, Rappaport, Placette Passive - there are more, but you get the point. Until I got the 10A, I struggled to make the other components live up to their potential." The 10A has been Rich's reference preamp for over 4 years. However, Richard now owns the 11A preamplifier as his reference preamplifier.

Eric: "The 10A excels at tranparency. Not in the sense of being overly analytical, but in the sense that you hear the music as if it was live."

Bob: "I liked this preamp…a lot! When I first turned it on, it seemed a bit dark and lacking in air, but in the next 30 minutes, the change that took place was amazing. If there was one word I would use to describe my experience with the 10a it would be evocative…or compelling. But wait, that’s two words isn’t it?"

Earlmarc: "I wouldn't overlook the SAS Audio Labs 10A preamplifier. Bound for Sound magazine did a review comparison of both the Ultra Verve (DeHavilland) and SAS 10A and Martin Dewulf preferred the 10A over the Ultraverve..."


10A Triode Stereo Preamplifier Features, Specs, Shopping Cart Below:

Welcome to SAS Audio Labs. The 10A is known for pure, emotional, unadulterated, life like music. This is one serious preamplifier that has a magic midrange.

SAS Audio offers two models, the "Basic" 10A and "Standard" preamplifier versions. Both are identical except the "Basic" has 3 inputs while the "Standard" has 5 inputs. Swapping out tubes requires simply removing the cover. One or more the inputs can be setup for lower gain and a home theatre bypass can be added upon request. As seen in the reviews, this is one serious preamplifier. Be sure to check out our specials (see link at top of page). Talk about reliability; only one 10A has needed repair since the 10As debute in January 1997, gold plating loosened from one filament tube pin.
