best budget pre used


Hi all...

i'm looking for advice on which pre might sound best w/my setup consisting of:

b&k st-140 > maggie MMG / mirage sfx-8 sub

I plan (eventualy) on getting a benchmark DAC-1 as my front end and bypassing a preamp entirely, but I need something to get me through for a while. anything at all will be an upgrade from what i'm coming off of.

so, anything in the sub $300 range will do. I see plenty of cheap rotels going for under $150, but i have to wonder.

thoughts?
would a b&k pre be best suited to the ST-140?
a tube pre? I'm eyeing a few within my pricre range. I love the tube sound, but I hear this ST-140 is warm sounding on its own and would rather have something clean and clear ahead of it.

thanks...
I apprecaite all of the great advice given to me over the last month or so.

There is a Cambridge Audio C500 that someone is selling here for $155 including the optional remote control which cost $50 by itself. The C500 is one of the nicest sounding super low cost preamps I've heard, that is modern in features like a remote control, etc.

If you can find an old Superfon preamp, it would do nicely also.
Try an FT Audio or Another Passive Pre .The only way you'll do better is if you get into the $1500+ range.

Creek,Channel Island and a few others also make Passives ,but you'll have to match them for gain with your system.

I have a B&K ST-202 and was using a pair of Maggie 1.4 before moving on so I have some idea of what will work.

Happy Hunting!
great ideas...i'll look into all of the suggestions.
