Yep to many to mention.
I have a Focusrite Session Pack with the digital
expansion, total price £1400. Is fantastic for vocals, and everything else that goes
through it. Zero noise loads and loads of volume. Also has a compressor for extra zing.
The digital board turns it into a stereo analogue to digital convertor aswell, so
you could add a stereo mixer to your setup and use the preamp at the same time.
I agree with Paul about weak links in a chain, but if you put a quality padlock at the
start of your chain then every thing else will be stronger. Unless one of your links is
made by Behr..... no I wont swear.
