Tenor 75Wp monos & Amati Homage

You need to be very sure that they provide sufficient power for your listening level. The higher powered Tenors might be more suitable.

Andrew,

As a Tenor/Amati owner, I recommend you put the rig on a 20AMP circuit, with power cords suitable for 750W loads, such as the Elrod EPS-3S, Synergistic Des Ref Squared, or the Anacondas. Those Tenors love big cords ;)

Look forward to hear what you think.

BWhite to answer your question they are power transformers not output transformers. The Berning in contrast uses a sophisticated high speed switching power supply, no transformer. Two entirely different designs top to bottom to be sure.

Sonically, the Berning is the most transparent "non OTL", tube amp I have ever heard. At least in the traditional sense of the term OTL which is direct coupled from the output tube of the amp to the input of the speaker which on occasion only has a coupling cap. A point to be made is that the ZOTL design of the zh270 is a stepping stone enabling technology without the typical drawbacks of iron which can introduce hysterisis and core saturation limiting performance at the frequency extremes and can be a source of "fatness" in bass performance. With a proper load, nothing can beat a well designed true Class A SET OTL top to bottom. It gets music right, at least to my ears. The Tenor is acknowledged by many to be "the" best of this group although I haven't heard it in a familiar system. I have little doubt about a product when it is so well received by so many. The important factor is not the efficiency of the speaker but its impedance characteristics. 4 ohms is at the bottom end of what an OTL will drive without getting into trouble regardless of how well it is designed.

The Berning is an extraordinary product that can only be appreciated when realized what its design parameters and accomplishments achieve especially in its target price range and the variety of loads it can drive. It is really a tough amp to beat top to bottom under 5K and is quite agreeable to upgrades to enhance its performance well beyond its stock performance. This is NOT a hype product but a true breakthrough in tube amp design. Too bad many maninstreamers won't acknowledge it. The truth is in the listening.
