which tube mono blocks?

Jman,
I agree but had trouble with their reliability when I owned them. One of the Monos was faulty right out of the box.
Spectron,
my Atmas together with my Sound Labs are indeed a match made in heaven- as long as you are reasonable with your SPLs. If not, Siegfrieds are the way to go. A tad better bass control, but though not bad there either, not quite the delicacy or the uncanny closeness to a live event of the Atmas in softer passages.

I have sailed a long journey of amps, which sometimes makes me wonder if I should write a book on this topic:)

But the summary of the book would end up with summary of my amps (here I mention tubed or hybrid amps only even though I have had several solid state amps as well).

I have owned Conrad Johnsons, Audio Valve Challenger, Jadis JA-500, Lamm M2.1, Llano, and have also tried out a few other tubed amps for short while. My speakers have included Avalon Ascent, McIntosh, Legacy Focus, and various Apogees (Fullrange, Diva, Scintilla, Duetta, Stage).

My current Speaker is a modified Apogee Fullrange.

Out of all the amps I have owned or listened, nothing compares to Tube Research Labs GT-400 or GT-800. These
amps stand head and shoulder above anything else in terms of transparency, details, delicacy, balance, control, power, liquidity, or any other performance measure.

The next best amp was the Jadis JA-500 even though the Audio Valve was good too.

My current TRL GT-800 (weighing over 1000 lbs) is easily the final frontier in amps for me.

I wouldn't doubt that, but for $10,000 speakers, it seems a bit unrealistic to go with $140,000 amps even if it might be (remotely)possible to find them for $70k used.

Rodman9...- The Hurricanes surely pack a punch and a sweet one at that. They are a dream match for my Alon's which like a bit of power to shine. Someday I will take the plunge

Gallant diva, hm interesting: I've owned the JA-500, actually preferred the JA 200 for delicacy, used them both with stators, but they do not, for my ears at least, even come close to the performance of the OTLs I own. Just goes to show how tastes are different!
