32-bit 3200+ amd pc running xp Sonic Foundry Acid 6.0 M-Audio fasttrack USB interface ART MP studio preamp Logitech 2.1 speaker system MXL condenser and Blue Encore 200 mic (oh man I love that mic) I'm looking at upgrading two elements right now - my speakers and my preamp. I could use a new interface too, but that's another post. Anyway, here's my question- I've heard good things about the ART preamp, but I know most people recommend to switch out the preamp tubes. Knowing only a fair amount about tube types and having little experience, could anyone recommend some good general-purpose tubes for recording? I play a lot of acoustic stuff, with synths, lots of vocals which will need to be rich but not overly saturated, and I also will be laying down mic'ed clean to distorted guitar tracks. I'd like to stay on somewhat of a budget, so I won't be getting TELEFUNKEN tubes or anything like that. Any suggestions will be welcome, so long as they'll help me improve my studio. Thanks!
