What's wrong? Nuforce/Capri no better than Sunfire


Preface: this is regarding 2 channel analogue SQ.
OK. I know it's very early in the comparison process, and I've "only" critically listened for 2-3 hours. But whereas listening to speakers has shown clear differences (to a point), and the move up the B&W ladder from 9NTs to N803s was SIGNIFICANT, I'm at a loss on the amp/preamp. The jump from my old $4k Pioneer flagship HT rcvr to the Sunfire TGA5200 was very significant. Less significant but noticeable was the jump from the Pio as preamp to the Sunfire TGP5 as pre. I then read a lot about how a good 2 channel pre would crush an HT pre/pro. So I got the Jeff Rowland Capri. Have listened for quite some time and struggled mightily to justify the Capri, but I just don't hear ANY major improvement. Maybe some VERY subtle things, but I can't even be sure of that. I also read that a good 2 channel amp would crush a multi-channel amp. So I just picked up the Nuforce ref 9SEv2, and I've gone back and forth with the TGA5200, unscientifically, but again, I don't hear any major difference, whether through the Capri or the Sunfire TGP5. Am I just missing "golden ears" and reached the audio equivalent of the Peter Principal" (rising to my level of incompetence)? Is the Sunfire stuff just that good? Is the old claim that all good amps/preamps should sound similar true? It just strikes me as odd that so many people on these audio boards hear huge differences and I don't. What's wrong?

Hi Tvad: I orginally paired the NuForce 9SE's with a Counterpoint HC818 preamp. This was a very nice improvement over the Counterpoint Solid 1 amp I was using. After 6 months , I had the NuForces's upgraded to the V2 version. Major improvement. After a month or so, a friend of mine loaned me his Cary SPL 98 for a week. The improvement in presentation was more lifelike (but the bass response wasn't so great). I then, after a couple of months, bought a deHavilland Mercury II preamp here on Audiogon. This is where I am to this day. I had the output coupling caps upgraded to Mundorf Silver/Oil ones. Thanks for asking. Jeff
Yoby, I realize I incorrectly read your post. I thought your wrote, "NuForce 9SE V2 amps [are] really like tube amps", hence my question.

Thanks for your explanation.
The NuForces really do need a tubed pre IMO. I'm using a Cary SLP-98 and really, enjoy this combo.

Prior was an ARC LS26 which was also very good but I prefer the additional tube character the Cary brings.
Jim/Yoby:I asked in my previous post if anyone in NYC/LI area wanted to swap. A fellow agoner who lives here on Long Island emailed me(he's interested in hearing the Nuforce and the Capri) and he has the Dodd tube preamp, so maybe I'll get the chance to listen to the Nuforce with a tube pre. Maybe this is simply a case of system synergy. I read Yoby's response on the changes he's heard with the Nuforce and I wonder why I don't hear those things when swapping in and out the Nuforce and/or the Capri vs the Sunfire stuff.
