My Ecotec 600W/Ch Monoblocks
These are my Ecotec classs D monoblock amplifiers. Have to say that they are some of the best amps I have heard period.
You can check them out here:

Work in progress with my Sure TC2000/TP2050. Power supply was delivered yesterday, just got it hooked up today. I'm planning on getting/making a small case for the amp PCB itself & housing the power supply seperately on the floor.
And here is my Sure TA2024 powered ghettoblaster. Done 2 field tests now & ironed out a few flaws. Still need to buy a different power switch & drill then mount so it can be switched from the outside.

Rob's TA2020 build
This is my first build: a small amp based on Arjen Helder's TA2020 module. I love this little thing. Changing from my Pioneer HT reciever was like putting glasses on for the first time. So this is what hifi sounds like!
I also built some modest fullrangers based on Zaph's B3S design which I'll post in the FR gallery.
ATM I'm driving it direct from a PC with a Xonar card. Not ideal. Next project is a DAC - prob the gigawork.

I recently finished this 4-channel Amp built with two Class D Audio IRS 2x250 modules (they can be bridged to make a 2 x 500W amp, or a 3-channel 2x250, 1x500). I included a relay for 12V triggering by my receiver. The case is a Hammond 2U aluminum one (with my screws). I built this for use as a sub amp, but it sounds very nice with my Abbeys, driven from my receiver preamp.

Here are my small amps modules - a prototypes to a further project - nearly as small as big stamp so I called them StampAmp 
The modules are based on MPS chip MP7782. Starting them for the first time I was really surprised - the small guys sound really amazing driving my 4 Ohm ELAC 207.2 with JET tweeter.

VERY SMALL! looks like a nice clean layout too, whats the power ?
The chips are rated according datasheet at 50W with 10% THD+N what means definitely clipping in my understanding. I've got exactly the results, see the screen shots below. Continuous power of 40W without any heat sink for 1min - with small heat sink for 15min on 6R on the first screen shot. On the second 50W with clipping - is it 10% ??? hard to say Playing really loud music below clipping level you do not any heat sink!

Arjen MKIII TA2020 fits nicely in a cigar box.
It's been snowing today so I've been busy wacking together a little project. Actually,I am finishing up an Arjen Helder TA2020 T-amp and power supply combo that I started on last weekend. It is still breaking in so the caps are still a little shrill but just today it is starting to smooth out to the point I don't miss my ST-70 with the VTA mod so much.
Pardon the Cuban cigar box. I found it at Goodwill for a dollar (and I'm sticking to that story). The power supply box is an old project box which came in a box full of old 1940's and 50's toy train parts that I have used some of the switches and lights from too.The copper accents are from the back plate of a gutted Akai M-8 reel to reel that was converted into monoblocks last year.
Happy Holidays and enjoy the Snow!
