NC502MP should be similar as NC252MP below.@amirm
Hi Amir,
This type of measurement does not seem to be in this review. Any chance the measurements could still be performed?

If you also consider power, a single NC502MP goes up to 600W, which is more than a pair of AHB2 running in mono... for 6k usd! So you can buy NINE stereo NC502MP based amps from Buckeye for less than a pair of Benchmark AHB2!Look at the Power/Price ratio of the NC502MP in the "Amplifier SINAD List". When you compare the NC502MP entry to each amplifier higher up on the list it's a significant value/performance winner! You could purchase FIVE NC502MP stereo amps from Buckeye for the cost of a SINGLE Benchmark AHB2. Does the AHB2 sound 5x better or even twice as good? I would certainly like to try that comparison.

As long as you are not a pipe organ aficionado (needing those notes down to ?HZ), the results mostly look golden.If you also consider power, a single NC502MP goes up to 600W, which is more than a pair of AHB2 running in mono... for 6k usd!

Buckeye Nc502mp Review (6 Channel Amplifer)
This is a review and detailed measurements of the Buckeye Hypex NC502MP based, 6-channel amplifier. It was kindly purchased and drop shipped to me by our dear moderator, @AdamG247. I don't know what it costs. Not sure what there is to say about the case: Or the back panel: Other than...www.audiosciencereview.com
Buckeye 6 Channel Amplifier Review
This is a review and detailed measurements of the Buckeye Hypex NC252MP based, 6-channel amplifier. It costs US $1149 as of this writing. The owner/builder is @Buckeye Amps on our forum. The looks are fine for a well-priced build: The unit is quite light courtesy of rather thin sheet...www.audiosciencereview.com
@amirm probably forgot to run power x THD+N x frequency.It would be nice to see the actual measurements for the product under test. These measurements are very useful and almost almost always included.
Why are these measurements omitted for this product?
He does not test this for every amp. While I would also like to see this for the NC502MP, there is no point in doing it for more than one amp that uses the same module--this is not something that will vary by assembler/brand.It would be nice to see the actual measurements for the product under test.

Ok. YMMV. I have one dedicated 15A circuit for the HT. I have never had a breaker trip, even before the Buckeyes when I was using the B&K 200.5, and even when powering on after a 5 month absence.
I use a pair of stout UPS units that have a voltage drop setting with all my stereo equipment hooked to them (triamped, 2 TT's, 2 RTRs, 2 cassette decks, a tuner, an oppo 205 UHD, a CD recording system & various other things). When the voltage drops to my setting, the battery circuits kick in & stabilize the voltage to the 120V that it should be. I have never tripped a breaker since using these UPS units (on islands with intermittent power & all kinds of other weird conditions).
That is why a person should test & replace the UPS battery every couple of years. It is part of my maintenance do list. After the first time I had one die, I put it on my annual check list, just like the fire alarm & carbon monoxide sensor. I do not have a UPS that use a Lithium battery yet, But I have at least a small UPS in every room, with at the very least, an LED lamp plugged into them.The problem with UPS power conditioning is they begin to decline in power handling capability overtime. Customers with 5 to 10 drive RAID arrays would call me wanting to know why the RAID would no longer power up. My 1st question was are they plugged into a UPS. 80% of the time that was the case and it was 2+ years old. The UPS would loose it's power capability and did not have enough power to allow all 5 to 10 drives to spin up to start the RAID. The test for customers to determine if this was the issue was to simply plug the RAID(s) directly into the wall. Most of the time that corrected the issue. At that point, it was time for a new UPS or forget about it and simply unplug the RAID when not in use.
Bottom line, it will be hard to detect when a UPS is reducing your amps capability but it's pretty much guaranteed that overtime it's power handling will be reduced and your peaks will be rounded.

The same test was done on my NC252MP amp last year by Amir and as for as was noted it did not go into protection at 20HzThe NC252MP went into protection mode during the test. This means that the the assumption, absent measurements, is that MC502MP fails as well.
The power amplifier channels of most AVR's tested on ASR haven't gone into protection mode on this test, so clearly entering protection mode is a fail. That's unfortunate.
Any active preamplifier (or DAC that has a preamp mode) will take 1-2 V line level inputs and amplify it to 4+ volts for going into the power amp.Dylan has been tolerating me my email a bit... I'm a newbie
I've got a onkyo txrz that's supposedly 1v out... I'm thinking of going mini dsp to bump the voltage say the 10x10hd
Mini dsp say the hd boxes have a 12db boost which... Should get me (hopefully) ~1v boost without clipping... I'm pretty sure I'm going to order one as i went to process the signal. I'm not opposed to something like a drv134 to go RCA to xlr
Going off the hypex specs for the nc502 350w @ 8 ohms it needs ~2.7x volts to hit ~350w...?
Does anybody have some suggestions for bumping the voltage? I'm just trying to make a build of materials. Thanks in advance.

What's your AVR model? and most importantly the room size? , 350W @ 8ohms is max ... and that's not a good way to go about it, as per my understanding.Dylan has been tolerating me my email a bit... I'm a newbie
