8. Audio Nirvana 300B Single Ended Triode Vacuum Tube Stereo Amplifier
Audio Nirvana 300B Single Ended Triode Vacuum Tube Amplifier. 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 in our 50 years in audio. 8 watts per channel, but with enormous reserves for transients. 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 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. This is a ‘straight power amplifier with a volume control’. There is NO preamplifier inside, just a passive line stage. A $10,000 preamplifier can’t sound better than no preamplifier at all. No separate preamp is needed. Just connect any ‘line level’ source, like CD, DAC, Tuner, Tape directly to the A, B, or C inputs. If you do want to use phono, you will need an ‘outboard’ phono stage. We can tell you where to get a great one for under $200. Combined with Audio Nirvana single driver full-range speakers (25 models from 3 to 15 inches) you will have the best sounding audio system ever made. Average listening level of our speakers is 1/10 of a watt. More than 20,000 pairs sold, with 100% money back guarantee. In 15 years, we’ve had only 8 returns.
