Two comments:
1. Check the comments in this thread on tubes and use of feedback in a phono preamp.
2. I do not have a generalized conclusion valid beyond the unit's I have heard. In a recent review comparison between the tubed Atmasphere MP-1 preamp and the solid-state Esoteric C-03 preamp, both using an ARC PH7 phono stage, I heard less surface noise through the former combo, though the latter was quieter overall with no music playing. (Both excellent units.) Likewise in a comparison between three phono stages (the tubed ARC PH7, the tubed A-S MP-1 and the solid-state ZYX Artisan,) using the same linestage, I found the PH7 the quietest of the three in terms of surface noise. I suggest comparing specific units rather than making a decision from a general conclusion about tubes vs solid-state. Wrt to needing tubes throughout the chain, I'd say no.
