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. SAS Audio is receiving acclaim as a world class leader in audio reproduction. My goal is to design and manufacturer the highest quality products to help you achieve an audio system that sounds so real, natural, and lifelike that you will never feel the need to upgrade your preamplifier or amplifier again.

But how is SAS Audio actually different from the rest? Superior and unique designs for the highest musical quality, reliability, and reasonable price.

Each SAS Audio component is the result of years of research. Each basic design has sonic problems which must be minimized, if possible. Some designs look good on the surface but fail to meet stringent sonic requirements upon actual testing.

Parts quality is also paramount if optimum sound quality is to be achieved in the best designs. A great design using poor quality parts is not a great product. Each part is individually checked for clarity and for minimal artificial sonic character. Remember, no part is perfect but I choose the closest to perfection. (Check out my "DIY Parts/Price List" for ICs and other quality parts.)

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.

I check to see if a part will pass worst case scenario conditions. For example, if by some weird chance a tube in one of my preamplifier designs fail by shorting or opening, no other parts will fail. Only when these stingent conditions are satisfactorily met is the component ready for market. What is the record? No 10A line preamplifier has ever failed since the company's inception in Dec, 1996. The 11A has had one repair, a military grade resistor became noisy.

Only when a new finished component sounds truly superior and is extremely reliable do I offer it to the public.

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.

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, and were preferred.


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 also adds an additional loop of frequency dependent feedback through the power supply to further deteriorate the music.


  2. I do not incorporate parts just because they are expensive and add to the price, or are weighty, or offer a marketing advantage but does not help. 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 design and perform stringent listening tests to offer you the most lifelike music.


  3. 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. This includes hum, noise, soundstage, dynamic, colorations, all are forms of distortions.


  4. I am not part of any establishment, clicque, or for the moment craze. I am independent using different, solid concepts to create unique designs without being accountable to anyone else or group.


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

We list the features, specifications and shopping cart on each component page. I also hope you check out the wealth of information in my "White Papers" section.


Auditions

I would love to have you stop by and audition my components/system. Simply call or send an email with the date and time. Please allow a day before auditioning. (Directions)

Each page is designed to help educate the consumer when purchasing gear. From time to time, other articles and products will be added; so stay in touch.
I would like to thank God for inspiring the designs and parts used. It has been a real adventure, besides traveling to Europe many times, with His inspiration leading the way.
The articles covering theory require a special thanks to Walter G. Jung for discussions and his articles entitled "Picking Capacitors". Without these articles and discussions, these pages would be of lesser quality.
Thanks to Svetlana and JJ for allowing us to use their vacuum tube graphics on our site.
