Why? Do you work for Hypex? It sounds like you do.

Per the DIY thread owners of:
Atma-Sphere 60W OTL (appropriate speaker load), same user owns Clayton SS pure class A
Another A-S OTL owner (forgot model, ditto appropriate speaker load)
Accuphase
Other nice makes/models
...prefer their new Ncore not by small margins.
Maybe every single new Ncore owner will keep their previous amp(s). It would not be a huge surprise if some new Ncore user sells an amp he used prior.
My closest relationship to Hypex is I'm of Dutch descent as is Bruno Putzeys (he likely higher percentage than myself).
My friend in the Netherlands now just purchased a Dutch Tent Labs amp, single tube input per channel, transformer coupling, earlier Hypex output. In direct A-B he said it's "30-40%" better than the Australian Aksa NAKSA 100 now in my possession, one of the best amps I've heard.
Good designs coming from the Netherlands.
Just to put some focus on the difference an amp makes, which I'm sure most readers already know. My $90 Dynaudio Esotec domes are decent tweeters, though there are definitely better. The only thing between the domes and the amp is a Dueland resistor and a killer paper-in-oil capacitor.
Among other improvements, the NAKSA 100 makes the treble sound more than 100% better than the YBA. The upgrade just sounds like a completely different system.
After bass modes are solved (unless you settle for no deep bass, which is completely fine and often the case) and your source is ironed out, I think many users upgrade speakers way before the preamp/amp should have been replaced. With an inferior amp you have no idea what the speakers are capable of.
My 2c.
