Add Apollon to that list. And if stereo only, boXem and March too.Who is a good company to buy a Hypex amp from? Audiophonics?
It's a simple decision process if you follow Hammer's Official Gear-Acquisition Checklist, already updated for your convenience:damn i was just eying down a monolith 7 amp for the new onkyo reciever i preorderd... Now i see this amp!!! WTF do i do!!!
Pretty sure they are cutouts in the case for airflow.Are those heat-sink fins below the PCB_A (nearest MAINS in) and PCB_C, but not under PCB_B?
After my adventure with hiss from a NC502MP amp, I prefer they always be oriented with the PSU towards the front. Much easier to keep signal cabling well away from noisy PSU parts that way.Rotating PCB_C 180degrees will possibly reduce AC wiring length by half.
Nope. They come loose.Wouldn't good quality (highly conductive), tight-fitting (with respect to the hole in the case) sheet metal screws reliably cut through any powder coating or anodization without special washers, rotary grinding, or having to be careful of torque?
Nope. They come loose.
The thermal cycling loosens the sheet metal screws and then a bad ground occurs or even thermal runaway if there are clamped output transistors involved. I've worked in extruded aluminum and in threaded to sheet metal screw conversions and they both never worked out long term. If there is flexing involved I doubt the sheet metal screw will hold up in sheet metal. I think for a chassis a machine screw with locking nut and washers is best or has been mentioned a threaded stud spot welded onto the chassis. It takes seconds to apply with the proper tool.washerless machine screws/nuts would in a static application

Yes. I have read at least one report on here that the problems have been mostly or entirely corrected, but since the manufacturer does not choose to participate in this forum, unlike Buckeye, it is impossible to know for sure. Buckeye and March Audio seem to get the highest marks for quality of workmanship of all the Hypex amps--although there may be some European brands that are just as good and I just have not read the reviews as thoroughly. (And please note that I am simply reporting what I have read. I do not have the necessary knowledge to evaluate the workmanship myself.)Wasn't there a controversy with VTV in the past? Shoddy assembly from someone who bought one ^^^^^
PS capacitors r SusExamining the branding of the capacitors we find that the ones in the amplifier are from Aishi and those in the power supply, Sus'con:
BTW, I am always surprised by the amount of goop hypex puts on their amps. They are good to keep vibrations down and keep failure during shipping low. But I must confess I had not seen them put on transformer in that manner. I wonder if it is there to keep transformer whining down as a post measure. The goop makes repair more of a pain by the way as you can't just desolder and pull the part out.
I believe but could be wrong, that Buckeye does use some type of locknut on the underside of the ground connector. Maybe @Buckeye Amps can confirm or correct me on this?As others have said, there should be a toothed or otherwise locking washer on the connections. I'm 100% with @Doodski on seeing sheet metal screws loosen over thermal cycles and just over time. Not always, probably due to the metals and such, but often enough...
