Class D amps


I know Class D power amps are used in car audio applications. Why not for home audio power amps? Thanks.

Dob, I just finished my NCores yesterday. They are clearly better than my UCD400 monoblocks and I loved my UCD400s.

The NCores are more transparent, bass is tighter and there is simply more information presented. Without a doubt instruments and voices are more nuanced and the soundstage appears more defined. In complex passages everything remains sorted our, not that it was congested with the UCDs, but the NCores are simply better.

I was afraid they were going to be analytical or sterile based on some reports I read, but not in my system. I built my UCDs unbalanced and the NCores balanced. My front-end is the PS Audio PerfectWave combo with the upgraded DAC so balanced seemed like the obvious choice.

I did use upgraded Furutech XLR and IEC parts, Cardas Patented binding posts and Neotech wire for my internal speaker connections. But I used the same combo in the UCD400s. The only difference in my setup is the NCores and a balanced configuration.

If I had to say how much better I think the NCores are using a percentage, I would just take a stab at it by saying the NCores are at least 20-30% better except the soundstage. My UCDs threw a huge soundstage and the NCores are at least even, just more defined and nuanced.

I know my UCDs improved over time and if the NCores improve they will exceed the UCDs by a rather large margin.
Fiddler, did you build your NCores in chassis? If so, did you make your own or source from somewhere?
Drubin - Have you seen this thread?

These guys are way ahead on parts acquisition.
Drubin,

I used this chassis in all aluminum - 330mm x 280mm.

I was very pleased with the result.

Fiddler, I had a chance to hear the Ncore in my system and I use the PS Audio setup like you. I agree with you on how well they sound.
I have a friend who is looking to build a pair of Ncore and he was considering using the Cardas Patented binding posts but he had concerns that with heavy speaker wire and/or spades there might not be enough room to fit properly. Seeing how you have used it before how do you rate it.
