??? I used balanced XLR cables as input to it. If you mean output, they use a 4-wire "Kelvin" measurement scheme that route one pair to my dummy load and another to me AP AES filter and then to the balanced input of the AP. It is no different than any other amp with balanced input.So Amir, how did you use unbalanced or balanced in on your AP to measure this amp?

One thing I forgot to mention. The gain is a bit low. Usually I target 29 dB and here it is 25 dB. To get full power, I had to get about 1.6 volts or so. If you pair these up with an AVR, make sure they can produce their optimal output there.

Thanks for these comments.I see that they have a rack mount version and offer speakons. Also i like the protection/longevity the fans can add especially since you can use 4 252 making it 8 channels or 502 doubling power. Well thought out amp.
Never understood why most hypex based amps don't use the features of the module. It provides tempature, clip indicator, power problems from my beginner reading of the spec sheet. Yet most manufacturers stick them in a box and never connect to that info or cool the modules.
A couple things i don't like. 1) wish it was here in us to make shipping faster and cheaper 2) wish the fans were front to back allowing stacking
Also nice is that it uses 2 relatively big fans. Smaller fans and single fans are much louder. I doubt you could hear and with ASR testing they didn't come on.

Isn't it possible to sell them fulfilled by Amazon US? Build a few units and ship to Amazon US, and have them store and ship to the customers? Sure it must be more expensive on the product price, but shipping would be a lot cheaper (and faster) than international + customs, so in the end probably better for the customer. Of course this requires building and sending out a few units of each model in advance (working capital), so maybe just the top selling models? Food for thought.I am afraid I am not moving to the USA sorry
But as the power amp modules the same, aren't you just testing the input buffer modules differences?They don't run the same tests I run so we are stuck having to test them ourselves. Otherwise you can't compare them to others.
