Arrow IRS2092 amplifier up and running

After long time I finally built and tested class D amp using IRS2092.
Last night I did some basic testings and measurements.So far so good....Amplifier works on +/-45V...I am using IRS2092 and FDP2552 output FET's.
Design I used is very similar to reference IR design with some adds.
Currently working on new PCB that will have more Pout and some new mechanical details.
I will post some PCB pics and Scope pics soon...

Default Congrats!

Sounds very nice. Definitely interested to see more info.
And to find out your impressions on how it sounds!

I was thinking of something like this myself, but it'll be a while before I find the time.

this ic works very fine.
In the beggining i had some trouble with protection,but the fault was mine.I had to rebuilt the pcb.The best way to avoid problems is to follow all ir rules with this ic.
The sound is really great.
