How to DIY yourself very nice Class D monoblocks


If you want to know what the hoopla is about Class D and want to put together a very nice sounding kit I have a starter recommendation for you.

Go to Parts Express and search for "ICEPower ASP"
Next, look online for Ghent Audio. They make many sets of cases.

You'll need a high power soldering iron, and screw skills.
Between those two, you can put together a very nice monoblock for around $500 a piece.

I highly recommend both. I have no financial interest in either. 
You may need wiring kits, so make sure to order appropriately.

My TI tpa3255 evaluation board is the best solid state amp I have ever had.  My references for ss amps are mid-level pieces I have owned such as Belles 150a, Bryston 4BST, B&K, Aragon 8002, NAD units and such.

That is an interesting find! 300W/channel, and uses a very high (relatively) 2.1 MHz switching frequency!

It would be really nice to see frequency vs. phase plots for these amps.

Best,

Erik,

Looks like 500K switching to me.  The oscillator is in the megs.....not the PWM frequency.....maybe I don't know nothin.

George,

Your link to Gan-fet is from 2014 and Purely Emotional Audio is an offshoot of classdaudio.  They have yet to produce anything using that name.

Erik, TI has quite a bit of info on their website with plots for the whole chip family.  Interesting threads about tpa3251/tpa3255 on diyaudio as well.  The TI module is plug and play essentially and the sound is refined with some serious low end grunt.  Best with an active preamp. 
Hi All,
  Has anyone done any comparisons between the Bel Canto e.One REF 600 M and the IcePower ASP kit. I'm currently using a Krell FPB 300 with a PBN 741 speaker kit and a newer model amp is the last item on my improvement list. It would be great if Stereophile did some reviews on some of the kits.

Thanx,                                                                                                                     Frank
