I love your site, Steve. Just got a chance to read the Sytek review, and it was one of the many that contributed to my ordering one (they should be arriving at the beginning of next month).
I should probably PM you about this, but I figured some others might be interested in this as well . . .
NW Soundman and I just got together on a science project recently. The subject was a Bellari Tube preamp. Yea, I know, Bellari isn't exactly synonymous with quality sound. But their tube mic pres are the real deal, from a design standpoint. Their downfall is in all the second-grade parts they use (cheap input transformers, cheap tubes, and cheap opamps at the output).
A few years back, there was a mini-buzz going on at the RAP board about how some simple mods can greatly improve the sound . . . to the point where it is very usable even in a pro / semi-pro situation.
I sent one over to NW Soundman, and he basically swapped all the cheap parts out for some good ones. Not sure what else he did to it, but in a recent email he mentioned something about it being almost too clean for his taste now.
I'm excited to get my hands on it, finally. I will definitely post examples and comparisons.
