The 10A line preamplifier is one of only three preamplifiers listed in the "Exceptional Merit" catagory in Bound for Sound. Martin DeWulf has also purchased the 11A as a reference preamplifier. Richard Weiner, writer for Bound for Sound purchased an 11A as his reference, after owning and using the 10A as his reference.

Review #178, Bound for Sound, 11A Line preamplifier:
"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.)


Welcome to SAS Audio Labs. SAS Audio Lab preamplifiers have received wide acclaim as world class leaders in audio reproduction. With a degree in electronics engineering and 49 years of experience with tubes, 28 years in audio, rest assured of world class reference quality sound, with exceptional reliability. Each component is handcrafted quality for years of trouble free operation.

What sets SAS Audio apart from the rest? Superior sonic quality, reliability, and price.

My designs have no need of an additional sonic robbing ultra high feedback buffer or Mu stage (both include the highest amount of feedback). Instead I do the sensible thing and design (and use) one exceptional quality, low output impedance, ultra low distortion, very wide bandwidth stage to keep the music pristine.

As Mr. David Walker feels, of Walker turntable fame, question everything. I also feel the same way, never assume. I question and test every design including every resistor, capacitor, tube, and even the layout until the entire design "meshes" properly for the most emotional, accurate, and live experience possible.

Reliability is paramount as no one wants down time. The additional expense of repair, the possibility of down stream components being damaged is something no one should have to deal with. The 10A line preamplifier has never failed since the company's inception in Dec, 1996.

Of course, a great price is another extremely important consideration. When one builds a superior, properly designed component that eliminates redundant stages and the associated parts, and no warranty repairs which adds cost, the price can be exceptional. I also sell direct thereby saving the customer many thousands of dollars.

Jon L evaluated the 10A preamplifier and states: "It's just so musically engaging that this tube-rolling junkie didn't even try to roll any different tubes. FYI, that has not happened for any other tubed equipment that I've used..."

My philosophies and designs have stood the test of time as customers and reviewers have favorably compared the 10A and 11A linestage preamplifiers to over 45 high price and highly respected brands.


Basic Design Philosophies:

  1. I believe in a minumum number of correctly designed stages. Afterall, each stage deteriorates the music in and of itself, and adds an additional loop of frequency dependent feedback through the power supply to further deteriorate the music.


  2. I am not part of any establishment, click, or for the moment craze. I am independent and I think outside the box using different, solid concepts to create unique designs without being accountable to anyone else or group.


  3. I do not incorporate parts just because they are expensive and add to the price, are weighty, or offer a marketing advantage. I could easily add hundreds or thousands of dollars to the parts list and price tag and no one would question it. However, the sound would be inferior. Instead I use what creates the most lifelike music.


  4. I minimize all forms of distortions. Not only harmonic and intermodulatioin distortions, but any sonic signature that robs you of the emotions, the liveliness of the event.


  5. I use the best tubes for the design, not try to fit the design and parts to the tube. Huge difference.
