Hypex

Just searching around the internet and found
Hypex - doing a similar thing to the B&O ICE Power amps. Full digital amps. However the difference is that they sell the stuff DIY. I could be persuaded to have a go for these prices.

However, I would warn that the LC Audio stuff seems very fussy to noise on the line and grounding. I blew mine up because there was some noise on the line out of the audio-band :S

 

Neither Hypex nor ICEpower are "full digital" amplifiers. Neither claim to be. Both are analogue-input variations upon class D.

 

I've had a series of 5 new regulator boards from lc audio that have all died from purchasing an original two. After the last on expired I've asked for a refund ...I've one unit that is still boxed ...I can't use it as it will probably die like the rest. Thouigh theres not been a problem getting them swapped it seems they don't like to power a nos dacx or a dab board !

 

I have a pair of the Hypex UCD modules and also a little 41hZ Amp6,
I've listened to a few other Tripath based amps too.

I like the UCD technology, its reliable and does not seem fussy regarding speaker loads, the only thing I don't lke about the UCD is its input stage which uses AD8620, next thing I want to do is build a suitable discrete circuit (if I can find one) and feed the modulator direct.

I've got a pile of other popular diy class A and A/B amps for comparison
