Ok, lemme see if I can clarify my remarks. The RNP is in fact an excellent preamp with a frequency response that goes from a few Hertz on the low end to a forced roll off at 250kHz. It's full class A operation with a tone that will stack up well against other preamps in the $2500 price class.
The VTB-1 is also a damn nice preamp with a nice neutral tone, less impressive frequency response, more features, and it will also hold up well to many preamps that cost significantly more money. I haven't finished checking out the VTB-1, but at $179, it's pretty much a no-brainer decision so far, if you have a small home studio.
Medium size professional studios with a wider range of microphones are going to want to look at the RNP as a main mic pre, although the VTB-1 ain't too shabby either. As I've said before, I'm getting both.
Since the Really Nice Preamp name was already taken, I said the VTB-1 was a Pretty Nice Preamp. In fact, it's a very nice preamp, too, especially at $179. The fact that Alan just billed me $236.61 for mine doesn't change my opinion of the unit. He just better be willing to let me make payments.
