Bryston first digital amp

Islander · 12th September 2007, 05:03 AM

Hi,
I just stumbled onto this pic of the new Bryston digital amp
do these modules look like the hypex OEM 180 Ucd to anyone?
I am not trying to start rumors or anything , I just thought I' did recognized something familiar in those modules.

I think its not a Class-D amp, its a simple Class-AB amp with CE output stage

here is he schematic link

And the product link

But then, where is the class AB heatsink for eight 75W channels or 4 x 250W bridged operation? That's 1000Wrms...

It does indeed appear that those are the UCD180OEM modules.

I'm not a betting man, but even I would put money on those being Hypex OEM modules!
And if they are, it's good to know that mounting then so close to each other probably doesn't cause any problems with free running oscillator interference, because I'm just about to try the same thing!!

That is not the same amp. Note the huge heatsink area on the top of the 875Z, which is clearly not included in the image linked to by Islander.

I find it a bit funny seeing this, as it reminds me of this atrocity from a while back. I couldn't believe that words could be taken so far out of context until I read that. I guess the article writer for the Bryston website may want to converse a little more with the engineers...

From some "inside" source I know that they ARE Hypex UcD modules...

Some day, everybody will go digital...

...and AB amps will be cherrished like nowadays tube amps!

Cool the UCD's are that good! With a 20 year warranty.

Class-AB - Cherished like home theater enthusiast cherish CRTs.

Well, this Bryston 875 has an exception when it comes to warranty; 5 years only.

My guess, as they are using UcD, they want to cover their a**es if Hypex would cease to exist - because they can't replace/repair it at that moment?

Well, the Tripath Technology TA-2020 was introduced in 1998 ... 12 years ago. That's a long, long time in audio development terms.
