Whats the tubiest sounding preap?

Thanks for the info.Sean.
I did mention however I was looking for a pre w/an open design.(exposed tubes)
Your comments on the Connie J's interests me a bit.
I do want a pre that is very sweet sounding and maybe with a hint of maple syrup but I dont want the detail mucked up either.

P.S. does anyone like the sound of syrup? Wouldnt it be very smooth and sweet?
I would be interested to hear from people in the 'syrup camp'(if any)

David if you want syrup you won't find anything better than a Conrad Johnson PV-5. 500-600.00, right in your price range. It has a midrange rich and thick enough to sink in, real lusssh.

David,
Either a Conrad Johnson PV-5 (around $500) or a CJ PV-ll (around $700) would fit your requirements perfectly. I have used both. They're both great tube preamps with a beautiful, lush, warm midrange; great on vocals. I think that the PV-ll is a little better on the dynamics (zippier?), while the PV-5 is a little more laid back. I'm talking a very minor perceived difference. You probably would be happy with either.
