A question for fans of Threshold amplifiers

I'm very lucky to be able to hear numerous highly regarded solid state amplifiers in my home because I do professional reviewing.  In the last year I have been able to acquire three pristine re-capped E-series Threshold amplifiers.  These are a S/350e, S/550e, and a SA/4e.  When compared to some of the most highly regarded/high price amplifiers on today's market, not only did they hold there own, but particularly the S/550e/SA/4e, I found to be superior in my system.

It has been a long time since any threads have discussed any Threshold amplifiers at all.  So, I'm curious if there are any GON members who use any of the Threshold E-series amps and what your experience has been at comparing them to current production amplifiers.

Hey jsautter,

Here's your list that you didn't expect to get: Pass Labs, Bricasti, Boulder, Arye, D'agostino, among a few others.

Again, I no difficulties with you, just want to hear from present owners of Threshold E-series amplifiers to have a fun discussion about what their experience is with comparing these with current market amplifiers.

@Ping7507, Are you sure you have a 550 “e”? The earlier 500 non-e versions had only one. The later new owner’s made in China “5000e” might only have one as well.

Perhaps, I can add a request as well: can any one post the Stereophile measurements for the Threshold S550e?

It must be the model S550e. I don't know why the former owner did these things. I just hope that the original specifications of the transformer information can be retrieved.
