And on that note, I have some updates for those interested.
I spent all last evening playing around and swapping tons of stuff in my system. I tried my kingrex preamp I just sold this morning, even hooked up my Onix SP3 using a special cable to be able to use it as a preamp. I swapped the Ampino back in and then back out. I made sure the amps had all been on and at idle for a while, so I wasn't comparing a cold amp to a warm one. I swapped interconnects and even played with which wall outlets which components were using.
Conclusions:
The Onix is really noisy as a preamp

The Ampino is not even close to the same league as the Ncore. It has a warmth and a liveness in the midrange, but it also accentuates the high frequencies, an overall uneven up frequency response and way more distortion. Ncore just destroyed it in overall smoothness, micro and macro detail, imaging and soundstage, balanced frequency response and all.
But Ncore still didn't have that magic midrange or quite the high frequency "sparkle". I was back where I started...
Then I swapped my copper interconnects made by Tuan here on AC (called Sweet Spot Reveal I think) over to Morrow MA2's. Keep in mind that I had bought these last fall and did extensive comparisons with the SSR's. With the Ampino, the Morrows had a tipped up frequency response and a thin sound compared to the SSR'S, which had more body and also much more micro dynamic nuance and subtlety. They were key to getting that "magic" performance in the midrange and live energy from the Ampino. Morrows just didn't have that magic, we're more analytical and thin, despite having more air to them.
Well, things have certainly changed now with the Ncores. That live energy and magic is back, with benefit of all the awesomeness of the Ncores.
Just goes to show that system synergies can be everything. Seemingly small changes can make a surprising differences. And components that you had discounted in thorough previous comparisons can suddenly completely change what they offer give other changes in the system. I have learned these lessons in the past, and they're what led me to keep the Morrow cables despite not really liking them. I'm really glad I did and that I had them on hand to try now.
Now, I'm not saying my search is over. I still might be interested in the right tube preamp eventually, or maybe going up the line in Morrow or even something else. But my toe is tapping again for the first time in a while, and that's plenty enough for today
