You are throwing around some pretty broad brush condemnations of single-ended triode technology. Not all SETs are created equal. And they certainly aren't bandwidth-limited when done right. And dynamic range??? Again, you have to have the right speakers for those milliwatts. Planars are not it. Horns are.

Put a good SET on the T-1s and you will have all the speed and transparency of 'stats and planars (I owned 'stats for years starting in 1976) and dynamic range any speaker would die to have. If you haven't visited SET topology for a while (and it sounds as if you haven't), a lot of things have changed. Electronic Tonalities, (re)introduction of parallel feed, the use of constant current sources as plate loads, current-regulated DC filaments for hum reduction (my 45s are quieter than the Atmas on the T-1s), permalloy OPTs with wide bandwidth, excellent interstage transformers for driver coupling. And on efficient speakers, all that is needed is milliwatts.

You make an all too common mistake in making the Holy Grail "accuracy". Accuracy is not only unreacable, it's unknowable. You must be privy to minute details about the recording venue and session to determine "accuracy". Accuracy is another one of those audiophile terms (like soundstage and image and air), that we can thank Harry Pearson and his ilk for. The "accuracy" brigade won't listen to mono, because it's not accurate, nor good music recorded in stereo that doesn't do the soundstage trick.

When I hooked up the 45s full range (I had bi-amped) I realized what i was missing in the bottom 800 Hz. Detail was phenomenal. I heard things (yes, it a trite cliche) on my records that I hadn't heard previously.

On the bench, the amp reproduces a clean sine wave up to clipping. Don't have a distortion analyzer (it's on my want list), but I it would do well. suspect.

"SET heads" as you put it, have a different view on music reproduction than audiophiles. All I know is that when Pres cuts loose on "Please Don't Talk About Me when I'm Gone", he ain't - gone, that is. It is the most realistic tenor sax I've ever heard out of a music reproduction system. Ditto on Narcisco Yepes' guitar in Rodrigo's Concierto de Aranjuez (Spanish NO, Argenta).

The Atma-Sphere M-60s are better than 98% of what's out there. They are excellent amps. But that other 2% is made up of well executed SETs and goes where the M-60s haven't.
