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, 8 watts per channel, 52 lbs (25 kg)--$1550 with free shipping
Finally, someone has made 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 handwound in our own factory. The amplifier weighs over 52 lbs (24 kilos). 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 6V6 Ultralinear, 12 watts per channel, 30 lbs (14 kg)--$995 with free shipping
45 years of experience tells us that the best sounding 'push-pull' amplifiers use 'ultralinear' output transformers. Our 6V6 Ultralinear is based on several 'classic' circuits, but refined by our audio engineer of many years experience. Powerful, quick, deep, solid state type bass. Extended highs, smooth tube midrange. Why the 6V6? This is basically the ancestor of the EL84/6BQ5, but with a much larger glass envelope. As such, it runs cooler, lasts longer, and has less microphonics. 6SN7 and 12AX7 small signal tubes (the best sounding for each role). Handles three sets of inputs. 12 watts per channel, but with enormous reserves. If your speakers need more power than this, then you're not using quality speakers. High efficiency speakers use large magnets. You can't have great sounding speakers with small magnets. The amplifier uses an enormously powerful toroidal power supply, protected in a real potted case (not a dummy one as many companies use). Output transformers are massive and feature the extra set of windings that ultralinear circuits require--and are handwound in our own factory. 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. Beautiful polished stainless steel chassis--not cheap chrome over pressed steel that will chip and rust. Gold plated solid metal binding posts--not cheap plastic ones that most modern tube amps have. Quality Alps volume pot. 115/230 volt selector. The only amplifier designed with the best sounding speakers in the world--Audio Nirvana Full-Range.

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.

Big Joe II Class D, 20 watts per channel--$199 with free shipping
We spent a lot of time looking for a high quality, low cost amplifier for our customers. We listened to many inexpensive Class A-B, T amps, and Class D amps. Highly recommended by one of our distributors in Japan, the Big Joe II was the best sounding of them all. About the size of an I-Phone, it's rated at 20 watts RMS, but makes super low distortion up to about 14 watts. Considering that average listening level of Audio Nirvana speakers is only 1/10 of a watt, this is many times what's required.
We sell our Big Joe II with two sets of speaker wires: one 6 foot (2 meter) pair ending in male banana plugs and an adaptor pair that allows you to use any speaker wires you choose. The Big Joe II 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.

About the size of an I-Phone, the Living Amp is rated at 20 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 Living Amp has a passive line stage, internally, so no preamp is required. Just plug in your source, hook up your speaker 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.

"Out of the box, the amp is so good I can't stop smiling!"--Benjamin de Castro
"My Dad's comments, on the phone, was on how good the sound was with the new 6V6 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 6V6 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 6V6 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 6V6 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
