I'm curious as to how people think the Hypex modules stack up against pieces like the Bryston B-100, or Classe ca-2100. Those two seem to be the most recommended pieces, but I'm very interested in Hypex. Concerns being fidelity first, and even frequency balance 20-20k. Specs on all units are like .000000000001/2% THD, so not too much concern there.
Still waiting on the box I ordered from Modu to arrive. During the meantime I decided to rush right down to the local electronic supply house and pick up a cheap box so I could put this thing together just to hear for myself what all this Hypex talk is all about.
After I put it all together and pushed the on off button I hear this click sound. Must be a good thing because no other sound is heard and then those red and blue LEDs on the regulators began to glow so something must be good. I put my ear up close to the tweeter and nothing, woofer nothing, no hums buzzes just nothing. I set the router to play a CD and popped in the latest release from Christian McBride and mastered by Mark Wilder and slowly turned up the level controller on the Avocet. Pure clean sound is what I heard. After a few minutes I was curious about how hot the amplifier modules would get and to touch they started getting rather warm. After playing for about a 1/2 hour I checked the temperature on the heat sinks and at that point they were to hot to touch, right at 140 deg. f so I shut it down. Just putting it in the box is not enough, heat sinks are a must so after adding that it runs cool so far.
It's been up and running about 1 1/2 hours since I put the heat sinks on and still just warm to the touch after playing various source material at normal to moderate listening levels. So far it sounds good, clean and transparent.
I've been using a Bryston 4B SST for several years now and this is the first time the power to it has ever been cut off other than power outages. Before that it was a Bryston 4B ST that was on for 12 years. This Hypex amp may just replace that SST version. Now if those fine folks there at Modu could rush the box to me that would be great.
