Magico S5 review
I think people's opinion of "driving" a speaker differs dramatically.After hearing the S5s several times (including Vac 450s in a large room), the most successful pairing was on Constellation Centaur- which is 500w into 4ohms. 
Zu Druid & Definition Roundup
I don't have a sub amp upgrade on order, sorry Spirit. I would reach out to Gerrit though. 
Tell us your worst audio dealer or mfr. experience.
Andy Singer proclaming he had the best ears in the world at the Krell Evo 1 introduction back in 2006. 
Isolation Transformers -- Equitech or Torus?
Torus is a much easier company to deal with. 
DeVore Orangutan 96 an upgrade over DeVore 9?
I'm waiting for the Gibbon X to ship so I can finally demo it locally. I would wait to audition both it and the Orangutan.If you only want to use SET amplification, the Orangutan is probably a better fit. 
Ayre AX-5 Integrated Amplifier
Hegel and Ayre are both no feedback designs, yes? 
JC1 upgrade to Lamm M2.2 or dartzeel 108B or Ayre?
I've had the Ayre VX-5 and Dart CTH-8550 in my room and the 8550 was simply a better amp as it was more organic/3D. The Ayre had wonderful flow like the Dart and a very natural top end. But it just seemed like 2D images in a 3D landscape if that m... 
What are the best speakers for 80's hard rock?
Atmasphere- while I tend to agree, many speakers or combos don't exactly rock out.I heard Leben with Harbeth for example at a show that put me to sleep! 
Low heat alternative to FIRSTWATT J2 ?
Just a small correction- the J2 does have negative feedback.OP: Ayre and DarTZeel are the two A/B amps (cooler) that don't use negative feedback. The latter has a new integrated with built-in DAC which might interest you. 
Dartzeel CTH 8550 experience
I'm a big fan of the CTH as well. While expensive, I have not felt a need to upgrade in a year of ownership! I preferred it to many tube alternatives as well. 
Dan D'agostino Momentum Integrated amp
I don't how it sounds, but it costs almost double the Dartzeel and Vitus- almost 50k for an integrated seems excessive, period. 
Acoustic Zen Crescendo Mk2 or Daedalus Ulysses v2
fwiw, Mtrot there are several speakers that do provide the sound you're looking for.First are horns like Avantgarde. Second are Zu Definitions. I'm not trying to toot my own horn, but they are big, open, with great tone and dynamic as hell with se... 
Acoustic Zen Crescendo Mk2 or Daedalus Ulysses v2
I agree with Roscoe that these two speakers aren't ideal with your requirements. Both are more intimate sounding, despite size. 
Single driver speakers without the pitfalls?
Zus with the latest Radian tweeters are quite an accomplished speaker nowadays. Highs are very natural. With active bass on the Definitions, really an ideal compromise. 
Best Integrated, period.
It would be nice to compare the NuVista with the DarTZeel and Vitus SIA-25.
