Ultra SL Preamplifier

Our original Transcendence Seven preamplifiers have astonished nearly everyone who has heard them. Now be prepared to be astonished all over again. New for 2006, the Ultra SL preamp is better than ever. The secret: a new active ten stage high current, wide band, analog regulated power supply section, with separate regulator sections for each section of each circuit. For even more stablity and wide band low noise performance, the new circuits are all contained on a shielded ground plane mother board.

This extends the range, dynamic range, transient response, and clarity even further, with an absolutly grain free presentation and a huge three dimensional wall to wall and beyond sound stage. If absolute faithfullness to the music with nothing added or glossed over is your goal, you can likely do no better at any price.

We started with our basic patented design ideas that have worked so well, and provided even better power supply isolation between tube sections and mos-fet section with a much higher capability MOSFET buffer/driver circuit, all running Class A, and came out with simply astonishing results; the new Ultra SL preamplifier.

The Ultra SL preamp tells us that simpler is best if you can make it work to perfection, and we have. Our famous patented Fet Valve transimpedance gain cell just loves the high current drive of the 6N1P line tube and the much higher current gain of our power MOSFET design in the loop isolator circuit. The circuit simply comes alive with pure musicality, dynamic range, transient attacks, and range extension we had not thought possible.

Not stopping there, we designed a new headphone driver circuit to match the performance of the line stage. Now you don’t even need a power amp or speakers to hear music as never before, just high quality headphones.

To provide even higher quality performance and satisfaction, all SL chassis preamps now come in a new larger and more attractive chassis with higher quality gold contact pushbutton switches.

If you require more control options than the Ultra SL preamplifier offers and/or tone controls, be sure to check out the Ultra EC preamplifier. (Compare chassis features here.)

Available factory-wired in the SL chassis.

The Ultra SL circuits are available as factory upgrades to all existing Fet Valve and Transcendence SL preamplifiers. We always strive to support our existing customers with the most modern and musical circuits possible, retaining the quality hardware that does not wear out and need not be replaced.
