Introduction
We sell only the highest quality 'neutral sounding' amplifiers. We don't sell 'boutique' amplifiers, with a particular sound. Most amplifier companies sell these, so they can sell you a different amplifier every few months. We only want to sell you one amplifier, which you can keep for life.
We have not heard better sounding amplifiers, anywhere, at any price.
Our tube amplifiers are the only ones ever designed with, and optimized for, full-range and other high efficiency speakers.
Audio Nirvana speakers require only 1/10 of a watt for normal listening. So even our 300B SET has 80 times the average power needed.
Audio Nirvana 300B SET Single Ended Triode Class A Vacuum Tube Stereo Amplifier
8 watts per channel, 56 lbs (25 kg)--$1599 with free USA shipping
Finally, someone has made a Class A Single Ended Triode amplifier with deep, powerful, extended bass and highs that extend to the limits of human hearing. Together with the traditional smooth and detailed SET midrange, this is the best sounding amplifier we have heard to date. The Audio Nirvana 300B SET uses an enormously powerful toroidal power supply, protected in a real potted case (not a dummy one, as many companies use). Transformers are massive and are hand wound in our own factory. The amplifier weighs approximately 56 lbs (25 kg). Parts are chosen for the best possible sound quality--not because we want to impress you with 'boutique' names. Each amplifier is beautifully hand assembled and tested. To maintain the superb sound, there are no adjustments to be made--ever. Self biasing, no AC or DC balance to adjust. And made with the fewest parts possible and best sounding tubes.

Audio Nirvana EL34 Single Ended Class A Vacuum Tube Stereo Amplifier
10 watts per channel, 33 lbs (15 kg)--$999 with free USA shipping
Single Ended, Class A amplifiers are usually very expensive. And they still have small transformers and are not well designed. A great Single Ended design requires special transformers and the experience to make them properly. Unlike almost every other amplifier company out there, we wind our own transformers to exacting specifications. We have used our experience with Single Ended to develop the best circuit, and we use one of the most popular power tubes of all time--the EL34. Our Audio Nirvana EL34 SE has deep, powerful bass and extended highs. Together with the traditional smooth and detailed Single Ended midrange, this is a great sounding amplifier. The amplifier weighs approximately 33 lbs (15 kg). Parts are chosen for the best possible sound quality--not because we want to impress you with 'boutique' names. To maintain the superb sound, there are no adjustments to be made--ever. Self biasing, no AC or DC balance to adjust.

Big Joe HD Class D, 40 watts per channel with built-in DAC--$299 with free USA shipping
More and more customers are using their computers and portable devices to listen to high quality music. They asked us for a high quality amplifier with built-in DAC. We have been recommending the Firestone Audio Big Joe II, for several years. It was highly recommended by one of our distributors in Japan. The good news is that Firestone Audio now makes an improved Big Joe II, running Class D, and it includes a high quality DAC. With resolution up to 24 bit 192 k/hz you cannot find better sound. It is able to support USB, Optical, and Coaxial inputs. An adaptor is supplied for RCA inputs as well. Two sets of speaker wires are included--six foot (2 meter) speaker cables ending in banana plugs. And a pair of adaptors so you can use any speaker cables you like. About the size of an I-Phone, it's rated at 40 watts RMS. Considering that average listening level of Audio Nirvana speakers is only 1/10 of a watt, this is many times what's required. The Big Joe HD has a passive line stage, internally, so no preamp is required. Just plug in your source, hook up the included wires, and you're ready to go.

"You guys have hit the ball out of the park! The sound is wonderful; a dynamic, well balanced sound, that is very musical and engaging. It's doing everything well and there is nothing more that I desire. I'm getting everything out of audio that I ever wanted. I am experiencing the amp's excellent bass response. I plan to continue using the amp with the stock tubes as I am finding the sound fully satisfying. Thanks to you, and your associates, for making such an outstanding product available."--David Tanimoto (from Hawaii)
"I'm impressed, very impressed! This amp is the best money I've spent in a long time and I've spent $5000+ on amps before and was disappointed."--Dan Cordova
"Out of the box, the amp is so good I can't stop smiling!"--Benjamin de Castro
"I regard your EL34 SE amplifier as the best audiophile product I have ever heard and I owned. Two of
my 'audiophile' friends have Air Tight 300B amps they paid over $8000.00 for. I can hardly wait to insert your EL34 SE amp in their systems for comparisons. I immediately want to listen to all my favorite recordings ASAP. The music listening experience in my home has reached a wonderful level that I never expected to realize. Thank you for a GREAT amplifier."--Gary Schwerdtfeg"My family and I spend a lot more time listening to music, and a lot less time in front of the TV, thanks to your amazing equipment."--Stephen Fisher
"My Dad's comments, on the phone, was on how good the sound was with the new Ultralinear amp. He says it is nothing short of breathtaking and he just cannot believe how good it is. He said he is listening to his jazz CDs and it totally blew him away. He reckons the sheer separation and oomph, it has, is startling and it's all a little bit unreal in how good it all sounds. He loves this little amp with the big lovely sound."--Grant Thornbury (from New Zealand)
"The Ultralinear amplifier is superb, far better than I imagined! To say that the amplifier is amazing is an understatement! I cannot believe the detail that I am hearing in such a crisp manner. I am so appreciative of the quality that you produce for such an affordable price!"--Dan Robinson
"The Ultralinear sound is really different from conventional amplifiers. There are a lot of details and it is not necessary to use treble and bass. I can hear the whole frequency range with natural balance of all parts! Pink Floyd sounds better than it was with top semiconductor systems before! Thank you for this perfect amplifier!"--Timur Sarykulov (from Kazakhstan)
"WOW! Extremely nice work. No 'kit look' here. I have seen a lot of range when it comes to quality, and this is up there with the stuff I can't afford! I would like to thank you for selling one fine piece of gear (Audio Nirvana Ultralinear Amplifier). The craftsmanship is as good as anything I have ever owned, and I have owned a LOT of equipment in my time. Thanks again for your great product."--Greg Peyton
"I just wanted to say how happy I am with the system!!! The amp is fantastic, exactly what I was looking and hoping for, very transparent.....as are the speakers."--Chris Munkacsi
"I have been very impressed with the wiring in Audio Nirvana amplifiers. It’s one thing to price them well, but considering the quality of work done inside, which is very important, they are in a league of their own in terms of build at the price point."--Erik Mandaville
