If you love vacuum tube preamps, you'll love this one best, All new with a ground plane shielded mother board and ten active regulators.


The Transcendence Eight+ received The Absolute Sound's Editor's Choice Award for 2008. This great preamp has also received The Absolute Sound's Editors Choice awards for 2009, 2010, 2011 & 2012. Now, it is even better yet!TAS award

Of pure vacuum tube line preamplifiers, our new Transcendence Eight+ is easily the best we have ever heard. It is so musically outstanding, it replaces the Transcendence Five, Transcendence Six, and Transcendence Seven series in our product line. The T8+ circuits are available as upgrades to some of those models.

The preamp has a built-in multi-stage high voltage analog regulated power supply with separate regulators for each half of each tube. This makes a striking improvement in dynamics, transparency, detail, bass power and control, while still retaining all the "tube" virtues of simply smooth and pleasing musicality without stress or grain.

It also has high reliability gold contact pushbutton switches for the front panel functions.

Working from what we had already done so well, my vacuum tube specialist, Dean Kayser, has developed a fresh approach to vacuum tube design. With a huge, open, transparent, and simply lovable sound, the Transcendence Eight+ will get your attention because it is so faithful to the spirit of the music.

We build vacuum tube products because the very high voltage overload capability of a small signal tube, properly used, yields musical performance especially in the midrange that is so natural and relaxing that many purists demand it. Some of us suspect that part of what we like about vacuum tube sound might really be a bit of euphonic coloration. But the tube lover wants what a great tube design provides, and the Transcendence Eight+ makes life (and the music) easy for the vacuum tube lover. The price is nearly an order of magnitude lower than its audio salon-priced competition and the performance is great. If you want to hear what tube sound is all about, this is your best opportunity.

An amazing current buffered phono circuit is now available as a low cost ($199) option. This replaces the previous tube phono section and combined with the tube line stage, provides drastically better phono reproduction than ever.

The power supply is a modern and reliable solid state design with separate active analog high voltage, high current regulator sections for each plate of each tube and separate regulators for the tube heaters and low voltage components.

Our tubes (2 6CG7 type in the line section) are run below their rated plate voltages, are run on very heavily filtered DC heater supplies, are isolated from transformer magnetic fields, are given plenty of cooling space, and are not dynamically stressed with loads or signals they cannot handle. Thus we can expect many years of good service from our tubes and almost never see a unit for service because a tube failed and never because that failure damaged something else.

Unique to vacuum tube preamplifiers, the Transcendence Eight+features an exquisite headphone amplifier built-in at no extra cost. The Transcendence Eight+ features precision-stepped volume and balance controls and a silver contact fiberglass selector switch. It has left mono, right mono, full mono and stereo switches, a tape monitor switch, a tape 1, tape 2 switch, and a lighted power switch on the front panel. It has 20 gold-plated jacks for input and output to handle special, CD, FM, Spare (for VCR or TV), two sets of tape in, two sets of tape out, and two sets of audio outputs.

It is 17" wide, 12" deep, 3.5" high. The shipping weight is 17 pounds. It has our black powder coated steel chassis with black knobs, double-anodized aluminum faceplate with gold lettering.

Optional performance enhancements for the Transcendence Eight+ Preamp:

  • T8+ RIAA Phono Circuits installed in the Special location replacing one set of line level inputs.
  • Buffered Tape Outputs provide a dedicated fast high-current circuit, enhancing tape loop performance.
  • 240 V Wiring. A 120V/240 V 50 Hz/60 Hz international toroid transformer is available at extra cost.
