What Makes SAS Audio Tube Preamplifiers Different? | 7A tube Preamplifier | 11A Tube Preamplifiers
Bound for Sound, Issue #163 SAS Audio 10A Tube 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 recently purchased the 11A preamplifier as his reference preamplifier.
10A tube Preamplifiers Features, Specs, Shopping Cart Below:
Welcome to SAS Audio Labs. The 10A tube preamplifiers are known for pure, emotional, unadulterated, lifelike accuracy.
New to the lineup is the "B10A" basic tube preamplifier. The B10A is a standard 10A tube preamplifier without the monitor section and has 3 inputs instead of 5 inputs. Both tube preamplifiers allow removal of the cover to replace tubes when necessary. One or more of the inputs can be altered for lower gain upon request.
One can easily tube roll by simply removing the top cover if one just can't help it.
Features of 10A tube preamplifiers:
- Can drive 20k and higher input impedance amplifiers. (Has been tested with 10k ohm input Z amplifiers.)
- Vacuum tube regulation in the high voltage supply; NO solid state regulators or solid state current sources.
- Simplicity of the signal path. "Lead to lead connecting" (copyright©) whenever possible.
- No frequency dependent musical/signal feedback from stage to stage through the power supply. Again cleaner music.
- Most accurate sounding parts. This results in more accurate timbre of instruments and voices.
- Tube dampers, standard. This aids in better focus.
- High quality, expensive resistors, ceramic tube sockets, and some custom hiqh-quality polypropylene film caps.
- DC regulated filament supply
- IEC receptacle for AC power cord rolling.
- A three way switch in which one can "tweek" the tonal balance for more flexibility and better synergy with one's audio system. No more take it or leave it scenario.
- A robust 5 stage power supply provides better isolation from hash and interference from/through the rectifiers, transformer and AC line, for a cleaner, more open sound.
- Power Line (AC) reversal switch. One position always sounds better. Now you can choose the correct position.
- A 45 second parallel muting start up relay at the output, so no major thumps. No solid state devices or series relays touching the signal path.
