I was just wondering what y'all thought would be the advantages and disadvantages of using each of these as a bass preamp. Let's assume the user isn't interested in massive tone shaping, just a clean, direct signal to drive a poweramp. Here's what I've gathered so far (assuming the Demeter is the 1.5 rack space version with a DI, active and passive inputs, bright/deep switches): Avalon U5 - small, light -discrete (I'm guessing it has a more hi-fi and uncolored but also more "sterile" sound.) - sends the same signal to your poweramp as to the PA if you're using one, so you have more control over your sound thru the PA -"tone" filter preset knob (I have no idea what impact this can have on your sound, but I'm guessing not much.) Demeter VTBP201 - A bit larger, may need to rackmount -tube (may have more warmth and presence) -has an effects loop - Tame EQ, bright and deep switches - DI apparently comes before the tube and the EQ, so you don't have any control over the PA sound which may be much worse than the amp's. Which would you prefer and why?
