Teardown just posted: https://www.audiosciencereview.com/...ckeye-hypex-nc252mp-amplifier-teardown.18614/
It's always nice to see a room where the TV is mounted at the correct height. Becoming rare these days.Thanks for doing this review. I am considering HypeX Ncore 502MP vs 252MP.
Advice sought: My system:
I currently have 7.2.4 system primarily used for multichannel music listening (SACD, DVD Audio, Blu-ray Audio, R2R etc).
I currently use a Denon AVR-X7200WA for decoding/preamp via 5 analog outs to an Arcam AVR600 AVR used as a 5 channel amp for my main 5 speakers (B&W 802D, B&W HTM1 fronts, B&W 804D2 sides). The Denon drives my 6 focal speakers (2 x rears and 4 x in-ceiling). I have also two subs.
The 5 x B&W speakers all go down to 3 ohms around 100Hz to around 1kHz. The Arcam gives better bass and mids over the Denon. It was my old AVR prior the the Denon and I used it when I added the 4 ceiling channels a year ago.
I recently purchased 2 x HypeX NC1200 based amps. One stereo (2 x SMPS) and one 3 channel to replace the Arcam. This was based on a user’s experience with same B&W speakers as a stereo pair. NC1200 was the recommendation after user had tried many amp combos, from high end to HypeX. These have are not yet shipped so no comment yet on performance but I’m expecting an improvement with the new amps (less THD, better power/dynamics, better handling of low impedance speakers and better power supplies, user experience).
I‘m thinking if all goes as planned my next upgrade would be to replace the Denon amplification with 6 channels of HypeX NCore, but due to budget using the mains powered MP series, I‘m thinking probably NC502MPs. Then longer term, get a new AV processor then sell the Denon.
My 5 main B&Ws are all rated between 500W, 250W & 200W (fronts, centre & sides). My rear pair & 4 ceilings are rated 150W. (Actually all these ‘ratings’ are recommended amplifier power).
The question is: Should I get a NC502 or NC252 Ncore amplifiers?
Edit: The room:
I certainly was not talking about fraudulently claiming conformance, I'm saying that with a very high level of confort claim that this product is compliant. You are not legally obliged, for CE, not FCC, to hire a test lab. The high cost of the CE marking, really, is to get the certificates from all the part manufacturers, In this case it should have already been done. then make sure that cabling and soldering is ROHS compliant. The triggers are part of the Hypex design.
Again, it's a self declaration, of course don't stick this sticker if you are not certain it comply.
Great improvements. There were screws in the bottom plate already. I would just use those. If there are not enough, you can use a mix of the stick on and screwed clamps. That way even if the stick on fails, the rest will hold the wires down.Still looking for best way for securing cables without needing to worry about drilling more holes (but if it is necessary will go that route)
Do any AVRs allow you to use pre-outs for a subset of channels and use the internal amps for the rest?
Just to clarify, all modern AVR's (that I have owned or read the user manuals on), allow the use of any subset of preouts as needed.My Denon x3600 so far has allowed every combination i have tried using the internal and outboard amps as well.
This magnificent home theater deserves the NC502MP.Thanks for doing this review. I am considering HypeX Ncore 502MP vs 252MP.

Edit: The room:
Ouch the price is around four times higher per channel than Buckeye 502 offering . Nice amps though.This magnificent home theater deserves at least the NC502MP. In my opinion 5 channels of Purifi even better.

speakON's are available for all channel configurations. I am using 4 pole speakON's with cutouts for every XLR, so you can use one speakON for every input or one speakON for every two inputs/channels. Whichever the buyer wants at time of purchase, I can wire it either way.Very Nice!! Definitely pushing me toward the buy button. Will those be available for all channel selections? Hope to see a picture.
Do you also have a picture of the bottom side? Maybe a picture of an empty enclosure? I am concerned with venting and heat in general and would like to get a better idea of air flow.
I understand these are very efficient but with 6 - 8 channels per enclosure and no personal experience, I am skeptical. Especially when put in a rack with a total of 19 channels of amplification. I suspect space and external fans will be needed but I don't know if air would be drawn through the enclosure to cool.
Your amplifiers look very appealing, especially with speakons.
My point is that its shortcomings as a Class D amp has been lipsticked over by comparison to an AVR in the narrative. It is a red herring that misses the point that it is mediocre.
I've been thinking about this the last two days as I have gotten a good amount of orders recently. I have a good idea right now of how many I can fill with a 2wk lead time if only doing work for a few hours a night and on the weekends. It works well for me as I am at a point of my PhD where all my work is done in the morning....once my dissertation comes onto the radar in about 18 months that'll be a different story but a lot of time until then.
Since this isn't a business/living, worst case is I will have to have a longer lead time if orders pile-up. I understand this may drive away some buyers who are hoping to have an amp quickly. But for those who are planning an A/V setup or can wait, it works out.
Of course the lead time is an average. If I got (5) 2-channel orders all at once, those are pretty easy to complete in one night if I have all inventory necessary.
I'm being as fluid as I can be with this while being upfront to all those who contact me with interest regarding timelines, etc.
ImmunologyWhat field is your PhD in?
