Who is the No.1 in Class-D after Tripath?

diyroger · 3rd October 2011, 03:55 PM

Tripath was no doubt the King of class-D before it's bankcrupt. But who is the new king now?

Still have several TA0105A modules. Don't know wether there's any other new semiconductor companies that can beat Tripath in this field.

Define #1. Is this in terms of units shipped, revenue, company profitability, highest sonic performance...?

In this board, the most reputed (and for good reasons) Class-D amps would be Hypex. Do note that they don't come cheap. Hypex is about to launch a new product, the Ncore. Supposed to be a game changer, so we have new things to look forward to for 2012.

Do not bet on games of 2012. the surprise is always around the corner!

I mean those semiconductor companies who manufacture high performances class D amplifier ICs (like TA2022. Amp makers and those small chips used in mobile phones are not included.

IRS2092 with output FETs to suit your power need.

Populated boards are available from several vendors, "kits" (bare board and parts) are available from at least one. Sound is excellent, price is *low*. "Tripath" parts still seem to be available (made, apparently, someplace in China), but mostly for low power stuff. I lost interest in Tripath after working with the 2092 . . .

Aha, I just ordered a TA3020 board from siliconray.com, It's 600Wx2, not bad at all! I have several TA0105 module, which can used to build 500With easily. This is a very rare part

That would probably be TI, as they make the Crown Drivecore...
Not that you or I could buy that custom chip without the whole Crown amp.

I don't know how much Crown technology bleeds into their own Class D devices?
I've auditioned a few recently (as I have to test the EVMs) that impressed me.
Some of the earlier ones, lets just say I couldn't wait to get home and listen to
my vacuum tubes. I think TI must have learned something along the way...

If it was any good why did it go bankrupt ??

Technical excellence and marketing clout are orthogonal. Just look at Bose.

Tripath has inevitable high-frequency noise.

I turn even more IR. From technological IR has the best in the industry MOSFET technology.
