I can't believe I'm saying this, but I'm strongly considering one of these two companies. As stated before I like to hold onto my equipment for a long time. Seeing how these two companies have such a huge following makes me feel better about considering them. Even if I don't really get a deal on them, it looks like they could perform better than the McIntosh or just as good for a cheaper price. Right now I'm trying to research both companies and their products.I read your earlier post about reading the ASR reviews. If so, did you note the high quality of the Hypex Ncore Class D amps? They have superior bench measurements and tested reliability second to none. They are also much smaller, lighter and run cooler than other amps. Check out Buckeye amps or Nord amps. Very reasonably priced.

If you read through Arcam owner’s forums you will see lots of bugs and iterative firmware fixes over and over.
Also reading through Amir’s reviews you will often see caveats of “likely inaudible” meaning the extremes of SINAD and distortion will be certainly limited by your speakers and human ears. So buy for features and reliability.

Thank you for the post! I read it and was pretty impressed.Yes if the AVR is capable of driving the speakers to the levels the owners listen at there should be no differences.
You may not be able to drive the speakers to their limit either ? But if you don’t use that ....
The difference may show up in a larger room and or higher spl or both .
Figured you did, no worries. Some amps do have pass through, but it’s rareyes sorry
If you go with Nord they have RCA and XLR inputs plus they offer a $10 add on option that takes care of import duty fees and also gives you access to a US repair center for warranty repairs. I also note you can now extend your warranty to five years for a fee as well. This is new. At the time I bought mine the US companies were very backordered hence why I bought overseas. I have only heard and read good things about Buckeye. I do like the option of having both RCA and XLR inputs. I have used both on my multi8 NC252 now that I transitioned to XLR separates. Just flip a switch.I can't believe I'm saying this, but I'm strongly considering one of these two companies. As stated before I like to hold onto my equipment for a long time.

I will be too if I end up doing it. Which, right now I'm very close to saying yes. Can I/should I bi-amp the speakers through the amplifier? Somebody posted a 6-channel amp from Buckeye amps. Or would it not matter at that point? 200 watts is a lot of power for the 702 speakers.I'm really curious to hear how it augments your system.
Power is a cheap increase for a Class D. Just order a bigger amp. Instead of getting a NC252 get a NC502I will be too if I end up doing it. Which, right now I'm very close to saying yes.

I don't recommend bi-amping the Purifi modules, especially at such low impedance. You are already looking at 425 WPC @ 4ohms on the 3-channel Buckeye amp. Gene at Audioholics strongly advised against bi-amping on the NAD M23 unless the speakers were strictly 8ohms.I will be too if I end up doing it. Which, right now I'm very close to saying yes.

Class D are more efficient - therefore they produce less heat...Below link is from Audioholics string started by a knowledgeable member there and here. It is in support of Class D tech and presents a nice summary of attributes. Regarding longevity Class D amps do not produce much heat at all. Heat takes a toll on electronics.

Class D power amplifiers
Last time I shopped for the most transparent speakers I could find in the below $10,000 range I found them in a store in Toronto that powered the speakers with, surprisingly, class D amplifiers. In the end I bought the speakers without requesting them to try driving the speakers with my kind of...forums.audioholics.com
Some Class D come with both RCA and XLR outputs. Nord audio is one of them.
In some cases (from my own experience) Bi Amping is a way to get more out of multiple power constrained amps...I will be too if I end up doing it. Which, right now I'm very close to saying yes.

Your first sentence states a fact. The rest regarding Class D heat and reliability is speculation devoid of any references.Class D are more efficient - therefore they produce less heat...
But as a result designers aren't as particular about heatsinking, which can result in hotspots and unreliability.
Like any amp that heat will be in direct proportion to the load... hence low impedance speakers which require high current, will generate more heat than "standard 8ohm" speakers.
Most people won't have difficult speakers, they tend to be the exception rather than the rule... so the question of reliability, has to also refer to the use of the amps, their design (how thorough the heatsinking / cooling / active cooling is), and the speakers connected to them.
Looking at how most of the Hypex and Purifi modules are made and mounted, my concern with regards to long term reliability remains.
Has anyone taken FLIR photos of something like an ET400 under load (eg: after 1 hr driving 5W into an 8ohm load...)?

The Class D modules typically have an aluminium heatsink plate on one side, which is intended to be screwed to the case base - and that is the be all and end all of their heatsink...Your first sentence states a fact.

Welcome @HifiLover !Hello! Hope everyone is well. We're looking for new receiver for our room. Our budget is a bit over $4000. Unfortunately, it's hard to control the acoustics of the room. We are wanting to do a 5.1.2 setup in a 25x20 room. Our speakers are Bowers and Wilkins 702s2, HTM 72s2, and 706 S2. I'm between Denon, Marantz, or the new Sony line. HDMI 2.1 is important to us for Xbox X. This would obviously be for movies, games, but also 2 channel music as well. I steered far away from Arcam after reading reviews and measurements. Is there any huge benefit to going with a massive receiver with lots of channels when I'm only using it for 7 channels? Another idea I had was purchasing a McIntosh MC8207 (for a fantastic price) and pairing it with a Denon receiver with preouts. Would that be a waste of money? I've gone a little crazy reading lots of reviews from Amir and the rest of you amazing folks and got myself into a rut. I really appreciate any insight. Thank you!
It is worth noting that the FLIR images above, are under extreme conditions - the power supply was just before it shut down to self protect, and the NC500 is running at 200W hard load....I haven't used FLIR on my VTV Purifi but it barely even got more than room temp anywhere on the case at any volume, slightly warmer when idle vs high volume. The 3 ch Buckeye Purifi is slightly warmer at idle but barely wam vs when the amp is off. I can't imagine the Purifi modules suffering from prolonged high heat, based on my 2 amps with these modules.
