Class-D Audio USA have just released their new GaN amp at the CES

Thanks for the 'insider's view', George. If the development of D-amps continues at the current pace, the 60 lb.blocks can finally stop heating listening rooms....

Not to mention the spinal damage every time we have to move or clean them.
I want to see a GaN Class-d amp like Technics SE-R1 with it's 1.5mhz switching frequency for around $1500, it's not out of the question, just needs a different component change and little heatsinking. 

Cheers George 

My uncle is a Audiophile as well as myself and designs in pro audio, class D has made its mark the Gan circuits can be good but 
the design circuit also has to be created and voiced also properly around it.
it will progress over time ,but still in its early stages .in many cases the good old Vacuum tube which was called obsolete back in the 80s still in many areas still is the standard for realism and naturalness.being part of the audio circuit in a Power amp, preamp, or in digital there is a magic hard to ignore.

Never trusted Class D since Bob Carver's original brute circa 1980. So now Carver is doing tubes and Class D is high fashion. Stand long enough in the same place . . .

@hickamore....*L* Yup, and the landscape changes beneath your feet.

I'm a SS person myself, but having grown up with tubes and lived through the  transistor>chip>integrated circuit>MB 'eras', the 'new' is all I've known....*G*

I can appreciate the 'romance of tubes', and their 'sound'.  But 'smaller/faster/lighter' and eventually 'better' is the march we live with.

Of course, the 'better' issue is one that's still up to one to define and decide for one's self.  And I'm good with that...*S*
