Bernie: "I have also tested the 11A in terms of comparing the sound from my excellent cd source directly to amps versus inserting the 11A pre between. I could detect no difference whatsoever.... So, my two cents: the SAS preamps are stellar – with my 11A I hear no compression or any other alteration of the originating signal."
Graham: "I took the B11a into a shop in Auckland. I know the owner fairly well, and we agree that Shindo make some wonderful pieces of kit. (I wasn't looking for a change!) Almost immediately we started listening, he said "That's really fast!" We also agreed that the B11a was much clearer, making the Shindo Aurieges sound slow, muddy, and coloured."
Terence: "I have been using the 11A since I received it but I didn't want to be premature in my assassment, although my initial assessments were favourable. Now, I must say that the 11A is certainly the best preamp I have ever owned, and the best I have ever heard-ss or tube. Thank you for a wonderful product, Steve."
Charles Phd, does musical reviews for PBS, Florida.:I just saw this post and you know I have to chime in here. After three years of preamp auditions I just pulled the trigger on the SAS 11A preamp. It was an unknown product to me but Marty Dewulf over at BFS (and who knows whats going on there these days, by that I mean it seems that Marty has slipped into retirement - forgive me Marty if I am wrong) Anyway he always said wonderful things about the preamp! So having no mind of my own I bought the preamp from Steve at SAS audio. The reason I bought the preamp is that I did not want to do the crazy audiophile thing of always upgrading. Buying the SAS preamp was the best thing I could have done. It's wonderful! Clear, fast musical and very truthful to the source. And more importantly it works well with both tube and solid state amps (i.e. pass 30.5 & Audio-space 300b mono-blocks). Hey call Steve and ask him to make you one of his preamps.
Hey good listening
PS I have no connection to Steve at SAS audio
Bob: "Hey guys. . .if anyone's interested, I'm selling my Tram 2 preamp since my SAS B11A is so awesome...." (Tram 2 uses 45, 2A3s)
Ray: "your prees are somewhat legendary in their reviews."
Welcome to SAS Audio Labs. SAS Audio Labs is a small speciality manufacturer who caters to those whose discriminating tastes wish the most transparent, dynamic, most natural musical reproduction in the world. The 11A is the true reference standard on which to build, or to upgrade other portions of one's system. It is important to remember two things.
A 5 stage, properly designed power supply eliminates RF and EMI problems.
For sonic consistency, critical parts are within 0,5% tolerance.
No solid state regulation or solid state CCS etc.
Tube dampers, and chassis resonance control incorporated. Internal damping eliminates the need for special feet.
The output impedance of the 11A with typical 100pf interconnect cable capacitance is a superb -1.0db at 400khz. (The main frequency response loss of any preamplifier is at the volume control/tube input capacitance.)
Tube life up to 28,000 hours.
The 11A comes in two configurations, with options.
With either 11A, one can adjust the gain for either high gain (20db) or low gain (8db). (Not by global negative feedback.)
I have a special of $2500.00, one unit left. That is $449.00 less than list price.
