@altx, I’m not really versed in the intergrated market. iIntergrateds do offer value in reducing the significant cost of case work, reduced cabling and shelf space. On the other hand, if you notice the top pres often have separate power supplies, as do the Uber high end power amps. Typically separate power amps offer better isolation of noise and heat and better possible weight distribution. Often one will see higher class A bias, and or better power delivery into lower impedances from a manufacturers separates than from their own comparable intergrateds
Both the Hegel and the Ayre’s have received rave reviews. I haven’t heard the Hegel’s in any sort of serious context. I have no opinion on them. I’ve only heard the early Ayer separates. I found those Ayre’s too rolled off in the top end for my liking. YMMV. The more recent models have been described as sounding quite different. As I posted earlier, the CS 2’s with their 6 Ohm nominal / 5 Ohm minimum super smooth impedance, and fairly easy 88 dB sensitivity are from a technical stand point rather easy to drive. You should have plenty of options to choose from. Just be mindful of the CS 2’s sonic signature.
At these prices have you considered moving up the Thiel line?
