aidan,
did you see the Salvatore site??

"Trilogy 958 Triode Reference- This was an amplifier from England, which never had distribution in the U.S. Now it is discontinued and unobtainable. It is push-pull and uses EL-34 output tubes. In the recommended triode operation, it has around 60 watts per channel. Listening was done by one of my associates, who was so impressed that he ended up purchasing a pair. He has heard most, but not all of the amplifiers that are recommended in the highest classes. I have not heard them yet.
It has strengths in many areas including; superb highs, speed, dynamic shadings, immediacy, low-level musical retrieval and accurate tonality with body. It doesn’t get that last bit of directness that the best single-ended designs do, but it’s close. It works with a wide range of speaker loads, like the JA-80. The cost in England was around $7,500 for a pair. I have been told that the "secret" of this amplifier is its very unique output transformer.
According to my associate, this amplifier has Class B performance, and it was located there until recently. It still competes with the other Class B models, but it is essentially impossible to find, especially in North America, and no more will ever be made, so it has become more of a dream than a practical choice. For those fortunate enough to stumble on a rare pair of them, take immediate advantage of your luck, and don't let them go without checking them out."
