I'll agree somewhat Bret, that yes, McIntosh perhaps is still in the
stone age, with their Class B Amps, their big ole potted, clunky, boxy
Transformers (Seems all have switched to Torroidal), VU Meters galore,
in which not too many amps I've ever seen other than them have them
anymore (Except maybe for the Audio Research Reference 600 if I can
recall)

Many of them you needed a fork lift to move, but I can think of a few
other personal fav amps that are basically no different when it comes to
weight (Levinson #33, Krell FPB-600, and 650)

I don't know if I'd call many of the Macs PA Amps, :-) but if you threw
$30-50K in my hands, I could probably think of a good 1/2 dozen Amps I'd
prefer over any the Macs, past, or present.

Same with the Klipschorns. If you gave me a pair, I don't think I'd be
throwing them in the alley, lol, and I'll agree that they were a
timeless design, one in which even JBL somewhat "copied" with Speakers
like their old Heartfield, and Paragon.

I've heard some Threshold Amps if I remember correctly, about 5 years
ago, at Audio Consultants in Chicago (T400 was one of the models I
think?). They were driving a pair of now discontinued Wilson Witt
Speakers. Very nice indeed.
