Preamp with tone control.


Hello guys,
I need help to choose preamp. I'm building my system now and I will use Pro-Ject Xpression III turn table, Dynaco ST70 tube amp and B&WCM5 speakers. My question is, what kind preamp you can recommend for ST70 tube amp and, also I prefer to have tone control.
Found few preamps:
1. NAD C 165BEE ($899)
2. NAD 114 ($280)
3. AUDIO RESEARCH SP-4 ($550)
May be some one can recommend better choice.
Thanks!

Cool...and if you don't like it you can blame me. Weird thing...when listening to an ipod pluged into the "aux" input, I noticed sound bleeding into other inputs (like the CD input if I wasn't yet playing a CD and the pod was on). I assumed there was some design flaw in the preamp as I also assumed the ipod cable was OK. WRONG. I bought a Squeezebox Touch and some new Audioquest interconnects for it and the issue was solved...must have been crappy shielding on the other cables. Lesson learned.
