Magic in "flat earth" amplifiers (Naim, Exposure)

[alspe]

Is there any magic or different design mathod in so called flat earth amplifiers like Naim Audio and Exposure? If yes they have some oddities, what it is?

I have had many of them (british hifi) and it feels like they are little different than say Japanese / American power monsters. Sounds like they play music with groove, like it would be more fun to listen with them.

The Naim 110, 160 and 250 circuits were very conventional with quasi-complementary output stages even when they were introduced. About all that set them apart were somewhat unusual frequency compensation (for stability) and generous power supplies. AFAIK the newer Naim amps haven't deviated from that philosophy.

Naim always made a point of doing power supplies and grounding properly. This obsession does seem to make a difference, because their amps always sounded great to me.

Hello

Naim do also closely matche the input LTP transistors for VBE and HFE, this give a lower thd and also the sound do have a better soundstage.

Absolutely - put an unmatched parts clone with even better quality parts and larger PSU and it will still be an ordinary amplifier.
The matching and careful attention to details like placement of parts and wiring is the key. You don't maintain a reputation like
theirs by just topology or boutiquel parts, that should be obvious.
