PS Audio BHK M600 Power Amplifier Lab Report

Lab Report BHK's swansong is not simply a 'doubled-up' Signature 300 monoblock [HFN Jul '16] for although the latter is (still) rated at 300W/8ohm and 600W/4ohm, and the M600 specified at 600W/8ohm and 1kW/4ohm, the new M600 is more cautiously protected into lower impedance loads. So, while the...

For a hybrid design that has tubes in the signal path, I am impressed by the measurments knowing that PS Audio has historically done pretty poorly under the measurement lens.

PS Audio BHK M600 Power Amplifier

PS Audio grows its hybrid tube/MOSFET amplifier range with a new flagship that's the crowning achievement of the late and hugely respected designer Bascom H King Until this year, the flagship power amplifier in PS Audio's stable was the BHK Signature 300 [HFN Jul '16].

Well, yes, that's true. It's not bad as these things go. I'm not sure why I would pay 30,000 pounds for it, but maybe that's just me.

Yeah, it's hi-fi jewelry for sure. But you can say the same thing about luxury cars versus utilitarian cars.

Compared to the NAD M23 (Purifi) measured by the same protocols, the BHK M600 has better SNR!

Well, it should for the price difference. And being a staid, boring engineer, I don't need hi-fi jewelry

Horrified by the standby power consumption though...114 W. Surely there must be another "deep standby" mode to meet modern regulations in various places? It would seem not, only truly off via the back switch, then "idle" and "play" mode via the front panel button. Manual quotes 75W for the "idle" mode.

To be clear, I wouldn't buy or recommend this based upon price alone, but I was just pointing out that their high-end products actually measure well. I have my Yamaha MX-A5000 powering my home theater, a Marantz PM-10 powering my office system, and a pair of JBL 708P's in my studio. I am amplifiered-out with a collection of vintage amps that I enjoy bringing out from time to time.

Apparently the 75W standby is to keep it at optimal performance.

PS Audio BHK M600 Power Amplifier Are You Warm Yet?

Are You Warm Yet? With a host of power MOSFETs, and a PSU to match, each BHK M600 boasts over 600W/8ohm on tap, and some 25A in reserve to support over 1kW into low 2ohm loads. Each mono chassis pulls 277W from the wall at idle, a portion of this soaked up by the triode tube stage but most is...

"... a 'cold' M600 already shows a low 0.0055-0.006% distortion but after several hours of running this reduces still further to 0.00095%"

I think if you are one of the people who can afford a BHK M600, you probably can also afford a nice solar+battery home energy production/storage system.

Both of those figures are vastly below audibility.
