Let's make this interesting. For those with multiple amps, do your amps have 'flavors' and do you mate them with certain speakers/genre of music because of this?

...Not really. I don't try to match the amps to the speakers. To me, they either do their job or they don't, I want my amps to be invisible. The NCores are my preference because they do it the best on whatever is plugged into them. It doesn't hurt that they are the highest power amps I have either. ...And they run cold.
I tend to not listen to things on the PE APA, as I THINK (haven't measured) I hear more distortion on that amp than the others, whether I'm pushing it or not. That's the only amp that has a defined purpose - measuring/testing speakers

No, the Drivecores are not Ncore based. It is a proprietary integrated circuit chip pioneered by Harman International.

To my knowledge, the Purifi, Ncore, Pascal, ICEpower, and Drivecore are the only Class D amps immune to high frequency variance due to load differences.

I can try it that way, dual bridged monos, as I have speakon speaker cables made to do it. I ran them this way at InDIYana 2017. I normally use them as left front/left surround, and right front/right surround. That way the left and right are always separate once they leave the preamp.

Main amp: Home built Nelson Pass, Firstwatt diyAudio F6. Fed by a B1Korg Nutube preamp, or Motu M4.
(If you don't think amps make much of a difference - listen to a good class A amp - some of my friends were astonished. )
Shop amp: 3eAudio TPA3251 board, fed by Khadas Tone Board thru Shitt Vali preamp.

QSC RMX850 for the woofers - lots of power. Used up to 150Hz
Parasound Halo A21 for the mids - lots of power, very clean midrange. Used 150 to 800Hz
First Watt J2 for the horns - Class A, no crossover distortion, only 25W, but who needs power for a horn. Used from 800Hz up
None of the amps have flavors; wasn't what I was going for. It is important to avoid crossover distortion when feeding a horn, it's not a pretty sound.Francis

The ARC D52b sure sounds different than any of my others. It has noticeably more low end punch and is a little warmer/fuller than the others. I've always credited that with the secret Analog Modules they use in many of their products. It may run in Class A up to a point because it sure runs hot even at very low volume. It's great for small monitors that might be a little on the lean side.
I can't wait to get my Pass DIY build running. Just need to hunt down some PS caps and thermistors.Co-conspirator in the development of the "CR Gnarly Fidelity Reduction Unit" - Registered Trademark, Patent Pending.

Re nutube, sounds very good. Mine will ring a little if tapped, but soon quits - my diy enclosure is quite heavy, which I suspect helps.
Re: Cost - I am very good at hiding the cost of my audio projects from myself, could not tell you with any accuracy (: I did replace some of the caps with better ones (per ClaudeG's recommendation in the B1K thread).

I forgot to mention that before I bought my Wyred4Sound ST-500 power amp, I had a Quad 909 for many years and loved it (people who like their tubed amp's midrange would like the 909, too, or its current successor). I thought it had become defective in one channel and replaced it with the ST-500. Turned out the 909 was fine, but I really liked the additional headroom of the ST-500, so I sold the 909.
