Industry for sure. Yea, audio has been a hobby of mine for over ten years and just last summer I put together my own Hypex amps and figured I could do it for a business to help get more access to Hypex here in the USGreat are thinking to stay in academia or go in Industry! So Audio is a hobby then

Unfortunately, no. I don't do any of the cutouts/CNC machining.
The measured gain was about 25.7 dB. Converting into a ratio, it is 19.28 X (= 10^(25.7/20)).Amir, did you do a sensitivity measurement? How much voltage does it take to drive one of these amps to full power?
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)…….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:
Can you help me decide between the Buckeye Hypex NC252MP and the Buckeye Purifi 1ET400A amplifier, 3-channels? I want an end-game amplifier with tons of power for the most demanding end-game (high-end but not ultra high-end) tower speakers. My budget is $1800.Thank you for the review!
If comparing between those two and your budget is within the range of the 3ch Purifi, I would recommend the Purifi.Can you help me decide between the Buckeye Hypex NC252MP and the Buckeye Purifi 1ET400A amplifier, 3-channels?

I only do even channel counts so it would just be a 4ch NC502MP.Hi @Buckeye Amps
For the Buckeye Hypex NC502MP, is there a SKU for 3 channels or would it fall under a custom order?
I see in the review that these amps have very little headroom, attributed to regulated power supplies. Does this reveal itself in listening tests, compared to Class AB amplifiers for example?
I think I see what you're saying. I had been considering one of Buckeye's NC252MP amps, but maybe I should just go for the NC502MP instead.If you are driving both amplifiers in to clipping then maybe, of course you always have the option of buying an amplifier with sufficient power output that you never need to drive it in to clipping. As Hypex amplifiers are in general much powerful than class AB of the same price range it is very easy to make sure you have an amplifier with enough output that you always avoid clipping.

What impedance and sensitivity are your speakers, how loud do you listen, and how far back do you sit from the LCR?I think I see what you're saying. I had been considering one of Buckeye's NC252MP amps, but maybe I should just go for the NC502MP instead.
My speakers are Polk Audio Monitor 10Bs from 1986. They are rated 8 ohm, 89 dB sensitivity. Peak power handling is 350 watts. They got loud, when I had a harman kardon 700 series amplifier driving them way back in my college days, and I think that amp was rated at 70wpc, burst 90 or something. Now they are in a room about 750 sq.ft. and I typically listen to them at conversation level or slightly more, infrequently louder when I am in a mood or cleaning house.What impedance and sensitivity are your speakers, how loud do you listen, and how far back do you sit from the LCR?
Most of the time the extra power of the 502s is not necessary
The NC252 and NC502 will sound exactly the same within ideal usage....meaning if the NC252 is being used with speakers/scenarios that aren't clipping it, it will sound the same as the NC502. The only obvious benefit to the 502 is in situations where the 252 isn't up to task with power.My speakers are Polk Audio Monitor 10Bs from 1986. They are rated 8 ohm, 89 dB sensitivity.

What I appreciated about the hk amp was its ability to recreate the dynamic qualities of the music. That's why I was asking about headroom. In college, we could listen to some of the direct-to-digital recordings of that time (late 1980s), loud, but still get an appreciation for the dynamic aspects of the recordings. That hk died several years ago, and I have since been using primarily small Topping amps (mostly the TP60), but they distort long before I get to the volume levels the hk used to drive these speakers to.
So I decided to try out one of these Hypex amps. I can't afford a Purifi, but someone in another thread thought the Hypex 502, Purifi Eigentakt and some old hk receiver all sounded very similar. If so, that's the sound I want. You would know better than I would, I guess, if the 252 and 502 have the same sound, but per the above response from mdsimon2, I wanted to ensure I had plenty of power even if I infrequently made use of it.
I welcome your opinion on the matter, though.
