There also is a better high end driver that is a dipole.  It is an improvement over the Turbo S.

What is it about this dipole driver that makes it better?

So far I haven't read anything compelling enough to make me want to go down that path. I ditched a wonderful SET because it didn't play nice with the Turbo load, and I doubt it would fair any better with the TM load.

The TMs and the Turbos have a 100Ω peak at 30Hz. That aspect alone pretty much rendered my SET useless in the bottom end, meaning very little bass.

The M3 TM high end driver has more detail and refinement than the Turbo S.  Its not a dramatic difference, but it can be heard.  The addition of it being dipole improved the sound stage.

The crossover has better components over the Turbo S.  The lowering of the crossover point from 800Hz  to 700Hz eases the load on the woofers with a subtle improvement in the bass.

I am driving my speakers with 2 Schiit Vidars, so I have plenty of low end with power to spare.

I had my M3TS upgraded to TM, mostly to get the new dipole driver and to mate the speakers better with my 16 Ohm friendly amps.  No huge improvement but overall a greater sense of ease, as if everything was working with less strain.  Better sound when not in sweetspot also a plus.  I recently purchased a First Watt J-2 to try and while I still prefer my Shindo overall, the First Watt definitely brought better bass.  Now I am wondering if there is a good way to bi-amp these speakers.  BTW, I heard the new Spatial Audio speakers at RMAF last week and they were in another league.  Now I have to wait a couple of years and then look for a used pair, because $10K is out of my range.

New to the site.  Grateful for the many comments.  Running a pair of M3TM's (in M1 chassis).  Driving with Bel Canto 3.7 DAC and Ref 600's.  Started with M1's, then upgraded to the "better" dipole, then upgraded to the TM iteration. Originally amping with the BIG Psvane 845's (utterly amazing 50 watt 845 amps). But with original M1 configuration, upper frequencies MIA. Clayton suggested moving to SS.  This was heresy to a tube guy for the last 35 years.  While looking for SS gear to buy, I figured I'd try something light/cheap b/c the Psvane's just weren't "doing it."  Started with Musical Fidelity M1's (class D - $999 - 100 watts).  Thought I'd be underwhelmed, bored and disappointed. WRONG. I was actually astonished at the presentation.  Because the Psvane's weigh 100 lbs./each, I wondered, before upgrading the Spatials, if moving up the class D line might further improve the presentation. Bought a pair of Auralik Meraks.  Really fine sounding amps. More bloom, tonal density and far better upper frequency presence. In the meantime, I had the Spatials upgraded to where they are now the TM's.  All the while I was communicating with Clayton who was helpful and understanding of the issues.  In fact, I suspect that my early conversations with Clayton may have contributed to his decision to design the TM's inasmuch as we discussed my concerns over the lack of upper frequency detail when using tubes.   The Ref 600's sound so open, natural, and "right" that I'm wondering if I'll go back to tubes in this downstairs system.  I agree with the comments re: the dipole "tweeter" is a slightly more relaxed and slightly more refined driver when compared to the M27(?).  I never listen LOUD so it's possible that even after 150 hours or so, listening at no louder than 85dB, there is some break-in still required.  As I'm writing, listening to Illinois Jacquet "Birthday Party" and wondering if it's worth it to spend $1,000's more to buy the X2 (although I admit the tweeter in the X2 is more likely to provide the detail/texture that this M35 driver seems unable to provide).  Bottom line: I don't see myself returning to cones/domes in a box.  As I've aged I find the OB relaxed/open presentation preferable to boxes.  For those who haven't tried class D, remember that's how Clayton had been showing his products. And, again, this endorsement coming for a tubophile for over 3 decades. Who woulda' thought.  Grateful to have been able to read your messages and consider your thoughts. Take care all.

glynn,
what 16 ohm friendly amps did you try?

I have a pair of tubed monos, DIY, 40watt push/pull, AB.
they are set at 4 ohms and not driving the M3TMs very politely, but not adequately.
I can resolder my monos to 16 ohm, then will try them with the M3TMs, and see if it helps.

Using Shindo Montille 6V6 which has 12-15 watts.  Also used a First Watt J-2 which probably had same output into 16 ohms.  But then, I use a pair of the GR Research OB subs. When I first got these speakers as standard Turbo S I compared the 16 ohm loving Shindo against the Red something or other  (I am getting old and my memory is sucko) amps with a jillion watts that Clayton uses at the show and still preferred the Shindo, so power isn't necessarily the answer for me.  Now I can play the system so loud my cat complains, and she is a head banger at heart.  I imagine there is a powerful amp that I would prefer to the Shindo, but doubt if I could afford it.
