What are the other preamps that you have used with the stratos amplfier ? I mean other than the candela ?
I would appreciate any firsthand experiences 
I have seen people liking the Balanced audio technology and modright. Any others ?
technically I don't qualify as I have mono blocs, but here's what I've used in the past in one form or another:
* Quicksilver linestage...not bad but no where close to a Candella, but still has a couple of pluses
* Conrad Johnson PV10AL...quieter than most, but kinda thin
* ASL 2004 with upgraded caps....not as good as the other two, and not as quiet. Over was somewhat dull
* B&K something or another that I use to break in equipment
* Sonograph (?) ... hated it from the start, but had a very good phonostage (was too bright and a lot of CD like
glare)
* Conrad Johnson PV14 or maybe 16....really liked this one, but the Candella still have more presence and bass
in my system (I never heard this one with my glass ceiling amps as well as the B&K and the PV10AL)
What the Candella does right; the others will fall by the way side trying to do. But I think the candella would benifit from an external power supply and an isolated phono input (tape loop would also be a plus here as well).
I think our friend Alex should give us an SE upgrade path with four inputs (one being very discrete), or maybe add the tempest phonostage to the mix
