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?

Thanks Al. Interesting (though a bit overly technical for a non-techie like me, lol). Couple of observations: clearly I like the power/current paradigm better on my B&Ws, but I doubt these speakers were designed with p/c paradigm in mind. Also, I think that Bob Carver and this Sunfire design proves again that you can design a ss amp to resemble tube amps.

As I don't have a true tube amp to compare, is it possible that a tube-like ss amp offers the best combination/compromise for someone like me who wants that tube-like liquidity and bloom, but also wants ss bass impact and low heat/low maintenance? What ss amps possess these qualities? Based on Karsten's article and my ears, it seems McIntosh amps fit this profile: 1)they fit Karsten's power/current paradigm profile of having stable output regardless of impedance, and 2)everytime I've heard them I've felt the same way I do now with the Sunfire.
What other amps?

Tvad, what sayest thou?

Jeff - You have wasted enough time on Rowland and Nuforce. Get rid of that stuff before the word gets out about Sunfire. Once that happens, the separates won't be worth a plugged nickel. However, gambler that I am, I'll take them off your hands for an even $1000, if you pay the freight to 81521.
Do you have the boxes?

Jeffkad; You will notice a further remarkable difference if you do the following:

1. Get another Sunfire amp and run one channel through each of them. You'll notice a much better sense of channel separation and imaging.

2. Contact Marigo Audio and ask them to audition a pair of Ultra 5 power cords, one for each amp. You will notice a great improvement in how real, natural and detailed the music will sound.
