?!?
@maty,
What's the point to talk about the Denon 800NE here? Apples and oranges...
If THD+N appears to be wrong, how is it relevant to know about the performance of the Denon?... What are the calculations you made?
This is an important review due to the many products using these modules. The Emotiva PA-1 monoblocks use the same modules (I believe) but without the additional gain stage. I would imagine they measure the same or better. $630 per pair including freight in the USA, sales tax may be added depending on where you live.
Why on earth does anyone think negative feedback is bad?
Some designers said that traditional NFB more than 29 dB is a bad idea. Class A and class AB. With a lot of NFB you have very good specs, numbers but at the cost of musicality, a subjective paramenter.
Class D is other world.
As I said on others threads, I'm waiting for this one to be delivered this week (at least, I hope so...)Although this amp is ok, the 1200AS based Apollon has better specs, more power, better construction and is cheaper. Why would anyone choose the PS Audio??

the PS Audio seems to have a better industrial design/build.
Those are valid "emotional" reasons, but not very rational I suppose.Because it matches other PS Audio gear they have, perhaps they like the brand and like the 'info' they put out there, perhaps they like the looks ?
iiiìiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii...silenceBecause it's negative, obviously. Perhaps it would help if it were renamed positive feedback.
If I remember right this has been debunked, at least partially, and yes "musicality" is often used in a subjective way..

That these two trends exist among designers is a reality, with traditional amps.
To my knowledge it is not proven that much NFB is not counterproductive or the best. Links? Class A and AB.
Sorry if this is OT but the PA-1 really does seem too good to be true <https://hometheaterhifi.com/reviews...pa-1-balanced-class-d-power-amplifier-review/>. Can someone get one to Amir?This is an important review due to the many products using these modules.

Why the huge case? Literally a waste of space.Although this amp is ok, the 1200AS based Apollon has better specs, more power, better construction and is cheaper. Why would anyone choose the PS Audio??

Actually, it is not. Apollon choose to put it in a deeper case on purpose. The one on the picture is 292mm deep without binding post. Many customers want this size to stack with their others gears.Why the huge case? Literally a waste of space.
