Needed: Honest Advice on high-end amps- either mono or stereo

For great Sonics, it’s not just the amplification but rather the entire audio chain matters including a well sorted room.  For instance, @kerrybh  Zellaton Plural Evo speakers are highly transparent and can reveal the nuances of the very best amplification assuming the rest of the chain is also at a highly transparent level- unlike lesser speakers.

For the money (Let’s pretend you and I  can afford them- may of us can) are they transformative? Exceptional? WAYYY better than a lesser mortals out there? 

Typically, we’re not chasing a “transformative” Sonics but rather finding Sonics that “resonates” with us - draws us into the music.  A sound with a lot of WOW moments, touches the heart and soul deeply. It’s definitely worth it.  

I’ve heard the Michi amps and suspect those are hard to beat objectively.  Subjectively, anything is always possible.

Somewhat decent value.....not the best but better than many if not most comparable big, bulky amps.

I strongly considered buying but decided to cheap out and find a more cost effective and more importantly for me a less bulky solution.

The incremental value a $20,000 amp has over a $200 amp is $0 if you yourself can't hear it. 

Having said that, I'd suggest you listen to Luxman, a close sound cousin of D'Agostino even in the integrateds, Ayre and Pass as amps that can sound different enough to you to justify the spend. 

This is particularly important when selecting them to drive specific speakers as they will interact somewhat. 

I own 2 amps I swap between that I consider to be as good as it gets. A single ended class A tube amp from Dennis Had (Inspire Firebottle HO for High Output) bought when it was a month old or so in 2017 for around 1100 bucks, and  a Pass XA-25 that costs around 5 grand...had that for a few years. Does it leave me wanting some other possibly way more expensive amp? Nope.

How many people in this forum can afford German pre, ampli and speakers for $200,000? What are we talking here? Are we discussing audio or just bragging about $$$$$ ? Most of the forum participants would be, in my guess, in a range of $10K-$40K. I guess my place is not here. Sometimes there are real practical discussions, but they seem get less and less common.
