I am very curious about this board as I would like to make the transition to
class D operation. I have just finished a pair of MurphyBlaster Usher 2 ways and am very
happy with the sound. I am currently using a Behringer A500, which I think is a very good
amp for the money but I would like something even better!(For less, if possible).

Can anyone comment on the sound compared to the Behringer or an equivalent class AB amp? I have owned the original Sonic Impact T amp and performed the mods as per Panomaniac's recommendations. I thought it was quite good in the upper registers but lacked, ahem, Sonic Impact.

Another motivator for me is that I listen to music almost all day and would like something that
consumes as little energy as possible.

"2 x 100w would be perfect. "

These are 100W/4R at 10% distortion.

See the data sheet, the max is about 40W/8R and 70W/4R before the distortion climbs (clip).

I'd be happy with 40W/8R if the 1st watt doesn't hiss.

It is silent...
This is the Sonic Impact with impact!
This to me beats the Gainclones that I have built, fantastic detail with slightly less warmth than the GC's. Large soundstage..

I've ordered a second.

Default Arrived!

My board arrived yesterday evening. I have been listening to it the whole night

I am powering it with a 12V 3A laptop adaptor as I am still waiting for the 24V 6A Mean Well PSU to arrive.

Definitely I have to listen to it a lot more before I can say anything about it, but here is the first impression.

This amp has definitely got enough (actually a lot of) power. Mine is rated at 2*50W only with a single TP2050 chip yet it seems it's capable of generating good dynamic bass. It certainly has a lot more power compared to TA2020 and I think it can drive even "not efficient" speakers. And note that mine has got only one TP2050 and is currently being driven by a 12V 3A PSU. I wonder how it will perform when driven by 24V 6A and if yours are rated at 2*100W it should be even more powerful!

The heat sink does get a little hot even when powering it through 12V 3A and I wonder if it's going to get very hot when powered by 24V 6A PSU. It's not sizzling hot by any means, but if I keep my fingers on the heat sink for more than 5 seconds, I begin to feel a little uncomfortable.

The lows, mids, and highs sound well balanced and I like that highs do not sound harsh. Having said that, I do wish it had better separation and soundstage. How do I say this....? The sound is easy to listen but it feels like they are all *mingled* together and I don't know but *something* seems to be missing... maybe minute details in the highs and mids? But then considering the price, probably it's the greatest bargain I have ever had!

Can good input caps improve the soundstage?

Hi swkbkk,

Did your board come with caps across the input. These roll the treble off above 3.5kHz.
I removed these.

I simply added a couple of pieces of bent ally to the fins of the heat-sink. This lowered the temp by 10 degrees C..

Gentlemen; Don't mean to "but in"---but the Winsome Mouse that I own uses the same chipset and runs quite warm under all conditions. The design uses the case bottom as a heatsink.

Yes, the board comes with two small rectangular plastic thingy at the very same locations as your picture shows. To be honest, I don't know if they are capacitors but they have "BJ 6CA" written on them.

BTW, the back side of mine is not shiny like yours! Actually, mine is coloured in black including those plastics labelled "BJ 6CA".

Anyway, should I remove them?
