Class D is just Dandy!

I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.

That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.

For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.

Please share your experiences with class D amps!

Following on, at 200 Hz the output impedance is 10x better with nCore, but the absolute figures are tiny. The difference in output between a high and low impedance speaker is less than 0.01 dB.

Most "normal" speakers get very difficult to drive in the bass, not the treble, so for these owners, I think nCore and ICEPower are equivalent and subject to personal preference.

If you have an ESL though, I would really expect the nCore to over perform.

I am with you Erik, I have not experienced yet an amp based on ICEpower technology as mesmerizing as NCore NC1200.... THis includes my old beloved Rowland M312 based on ICEpower 1000ASP. See my review of Merrill Veritas on PFO:


http://positive-feedback.com/Issue68/merrill_audio.htm

On the other hand, not wanting to mortgage the future.... I have hardly heard heard all ICepower amps on the market, nor I can venture what ICEpower might do in the future.


For one thing, I have heard very good things about the little Rowland M125.... I It is based on a current generation ICEpower, and delivers 125W per channel in stereo mode, and 500W bridged.... Apparently super sweet... But I have not heard it yet.


Best, G.

Hi Erik,

     I just started reading your last post and clicked on your 1st link.  I took me to this Audiogon forum page instead of the diyclassd page I think you intended.

Thanks,
  Tim

Hi Tim,

I just tested it. It actually is a PDF download, so check your download files. :)

Hi @guidocorona

I wish I had a way to listen to an nCore pair without spending money. :) I would be better able to discuss the sound quality honestly.

What I can repeat, is that compared to Parasound Halo A23's which are heavily class A biased, I cannot hear a difference.

Best,

E
