Opinions on Nuprime vs D-sonic vs Red Dragon vs Class D Audio

Hello all,

I have over 500 hrs on my S-500 and thought I might comment a little about it.I think it's a step up in Sound vs nc400 and ref600m,these are the 3 class d amps that I own and I have access to more through a local audio club where we lend and or borrow equipment or occasionally listen to each other's systems.

I have been using a bel canto pre3 with all the diff. amps just to make a even playing field,the pre 3 is a pure water no coloration preamp.

The S-500 is the best class d amp I have had in my system and it has the warmest most engaging midrange with very sweet nicely extended top end that has more air and separation with the individual instruments making the entire frequency range very coherent.The bass is equally as good maybe better than my other class d amps listed.

I borrowed a Nuprime st10 to try out and found it too be a very close match to the S-500,with the nod to the S-500 for the best overall sound especially the midrange.

Offcourse this is in my system with my ears and judging the musical presentation that I prefer.

The next test will be comparison with a modwright kwa100se that I have owned for a few years but I haven't used it in about 3 years,I have loaned it out to club members though.I know it's a very good amp but can it equal or beat the S-500,only time will tell.

So many very good choices out there nowadays,


Kenny.

Thanks Kenny,  nice to hear that someone has done some comparisons firsthand. Even though its through your ears, its very helpful information.  If you ever hear of someone wanting to let go of their  Red Dragon Stereo amp, please let me know!  Have you listened to any of the other Nuprime amps?  Theres quite a bi price jump from their other models to the ST10, so I;m wondering if the sound is that much of a jump too.

Had the IDA-16 in for a trial and found it to be unlistenable during break in period and still harsh and dry treble after break in.   

Also got a chance to go head to head with some class AB amps vs. my NAD M12/M22 combo that I thought sounded pretty good and the class AB amps all sounded better.  They made M12 sound dry and analytical by comparison.  This was in a well damped dealer showroom that really lets you hear minute differences in gear.

I'm done with Class D.

Pick one with a 30 day return policy and don't buy in to the break in talk. If they needed to be broken in the amp maker would do this in advance. 

My Primare I32 integrated won out over an older Creek Classic 5350SE that was very well reviewed, a Belles Aria, and a Belles Soloist.

I realize that my humble integrated is not in the same echelon as high-end separates; however I believe that Primare is a company whose products employ some unique engineering and perform very well with about 24 hours of breakin. Notes just seem to appear out of nowhere and music is so enjoyable. On some of my better recordings it's like hearing a different, better version. (I won't say 'hearing them for the for the time.' That's bullshit.)

So you might want to add something like the Primare A60 to your list. I know how a list can grow and become paralysing; but I'm glad I took the time to listen to this product from a manufacturer I had never even heard of before.
