Which tubed pre to "flesh out" my mids???


Hello all...It is finally time to insert a linestage between my Wadia 302 and ASL 1009's. Ultimate priorities are a rich, lush midrange, and a tight bottom end. My preference leans toward the euphonic side, but I can't sacrifice much detail or dynamics to get it. I won't get a chance to audition much stuff prior to purchasing since I'll be buying used off the net...so if anyone has a clue how some linestages will work within my system and to my stated taste, any help would be appreciated...TIA.

Some contenders are the Joule LA-150mk11, Cat Ultimate, Supratek (forgot the model), Hovland (forget the model again), basically anything under $3k used thought that may rule out the Cat.

I replaced a CJ Premier 17LS2 with an Aesthetix Calypso and couldn't be happier.
Any tubed preamp in the Blue Circle line (BC 3, BC3000, etc.). BC preamps really shine in the mids.
Save your money and buy an Eastern Electric Minimax then experiment with different tubes. This thing is a Chameleon.
Audio Note Kits M3 MKII. bellaextreme dot com can assemble one with their own flavor of paasive parts. I'll never part with mine.
Joule-Electra issued, just now, super killer - to be shown at CES 2009 and I would start right there. Their previous preamp received Golden Ear Award from Harry Pearson of TAS last year so I presume this one should be indeed the "killer"
