Default 200W IRS2092 Amp for $20

This was moved over from the TDA7492 thread since it was off topic.
********

A little OT, but wanted to let you guys see what just came in the mail from Aliexpress...

These things are pretty compact - a little smaller than YJ blue/black 3116.

Very nicely made, appear to be quality components and very clean soldering work - IRS2092 200w monoblocks for $19ea shipping included. I am using qnty 4 x 19v laptop smps bricks in series for +/-38v supply (4.6amp limited) as the power supply. Testes it with some PA drivers and it is loud and clean. A great deal - easy to hook up and use - just need dual rail supply is the only downside. I may have to buy a Connexelectronic dual rail SMPS for $50 to get the real juice.

Recent price drop now $16

Update (June 19, 2015): I testes this with the $20 Abletec dual rail 53v power supply and it works very well. Clean and loud.

I had a modded IRS 2092 few years ago,
I can be wrong, but as far I remember,
I didn't find any big différences between 3116 and 2092.
For now, I am quite happy with 3116
Maybe I should set up a new test.

That's a good thing that you did not think there was much of a difference because the 3116 is one of the best sounding amps in the sun 40w range. If you need 150+ watts though, the IRS2092 can keep up with the demand. I have not had much time to listen but it sounds very neutral so far. A good amp should not have a sound of its own.

1/ I agree your feeling about the IRS2092. There is something more neutral, and maybe something else. It is a pure class d sound, so after 1 hour of listening , just need to turn off the music.

2/ I have only one 3116 in a big room with 2 big ditton speakers and volume is not at max level.
=> I think there are things I don't understand on amplifiers because I don't understand the run for watt.

That Abletec power supply is a Buyout for $20 at PE and specs show 4.15A capability for 5min and 16A for 10ms for hitting peaks. This is quite the deal as a PS for an IRS2092. Get them while they are still around. Free shipping as usual for $100 orders. Now a $40 200w IRS2092 is a great deal !
