Class D amps,bang for your buck ones

Hello

First off,

I don't know much about class D amps, I did buy a Sonic Impact T-amp from Parts Express once to play with, I returned it because I don't have the speakers for it.

I did manage to hook it up to a pair of BIC Venturi horn speakers, and was floored with the clarity of the amp.

Those speakers had so many problems that I just didn't want to monkey with them, bad x-overs with busted pots,only sometimes could I get them to work right.

So, this leads me to my question.

Whats a high value class D amp with some hp/balls to drive normal speakers?

I'm looking for the Forte 4 of class D's, assuming (class D)is a tripath based/type amp.

Any suggestions or comments welcome.

I have an Accuphase pre and a minimax pre to use.

Thanks
mcgarick

PS Audio GCC series uses ASP ICE modules. Available in 3 ratings and use the PS 'Gain Cell' input. These are integrates.
PS also made basic amps without pre section.

My Maggies seem to be enjoying themselves with the GCC250, which doubles up at 4ohms.

ICE is not a 'chip'.

Yes, Tim, I believe you are right. the GainCell is proprietary.

As a result, methinks, the input impedance of the PSAudio gear differs from that advertised for the ASP modules.

I'll check out the review, but am reluctant to crack a case at this time. It'd be a lot of hassle freeing it up.

I've heard it and repeated it.....that the 'd' amps using the B&O modules have more in common than differences (sound-wise), but is that TRUE?

Has anyone simply lined a bunch of 'em up and gave a reasonable listen?

The case and front panel...not to mention the backpanel layout is so similar to the PSAudio it makes me wonder.

I haven't read EVERY word in this thread, but has anyone mentioned the DIY aspect of the question?

Hypex 'd' amps and power supply parts are available and can turn into quite the nice amp.

International Rectifier makes a 'd' amp....which also needs a PS. I think the are an OEM supplier to a few manufs.

B&O doesn't make modules available to the DIY crowd. I suppose if you were willing to buy hundreds...if not a couple thousand, arrangements could be made.

Has anyone but me noticed that the W4S looks nearly identical to the PSAudio GCC series? I just looked at a backpanel photo from W4S and the differences are tough to spot.
Do (did) these amps come off the same line? Same sub? Did the PSAudio guys sell the 'rights' to the design to Wyred?

I'd like to compare the Wyred to my PSAudio in my system. Wouldn't surprise me to learn the differences could be covered by a single finger.....
