class d

I want to hear from people who has had experience with these that did not work out and why,all you hear is the positive.I'm not wanting to bash them whatsoever, its just there are people that dont like them,im curious why.Yes ive had a couple,they didnt actually sound bad,but they didnt draw me into the music at all either.

More conversation with nuforce. They gave me directions to open the pre and move a jumper to cut the gain by 1/2. So I gave it a shot but when I opened it up it didnt really look like he picture. Turns out that the demo version i was sent has an old board without the jumper. But they offered to switch it out and if thatw as not enough of a reduction, the offered to add resistance if I wanted. Not bad from a service standpoint.

I actually had a different issue with the NuForce V2 SE and my Supratek Chenin tube preamp. The RF emitted by the Nuforce fed back through the tubes in my pre, producing a contant buzz/hum through the speakers, and a very glaring type of sound - rather unpleasant. Be careful matching the NuForce with tube preamps, especially Suprateks. The Supras are very sensitive to RF - I can't have a cell phone in the same room with them, or I hear every ping of the cell tower loud and clear. No such problem with the Gilmores, however.

No guarantees, but the Rowland chassis is designed with containing RFI in mind. Some of the worst of Class D or ICEPower impressions comes from these kind of issues. It cannot be ignored. Besides interacting with pre-amps, setting your CDP and ICEPower amp side by side can be disappointing. With my Rowland Continuum 500 and Playback Designs MPS-5 it's not an issue at all, either in unbalanced or balanced mode.

I had not looked at it from that angle, but can't really argue with you either. The p9 demo was not part of their usuall demo process though.
On their web site, they offer auditions for the monos. So I called the to arrange a demo. While on the phone, I asked about the p9. The guy said that they didn't have a demo program for it, but that he had one handy and wouldn't mind sending it along.
So I can give them a "pass" on not knowing that the pre wasn't current because they weren't planning on sending it out.
That says nothing about the rapid rate that they upgrade the amps.
I am really fond of the solidity of the imaging that I get from the pre/mono combo. Plus the pre suits my quirky functionality needs (ht bypass, balanced input and output) and they are cheap.
If anyone has an alternate to consider, let me know!
