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.
Also, some of the Van Alstine preamps have bass/treble controls which are defeatable. Used they could be within your price range. Of course, there's always an old Dynaco preamp, which can be had cheaply and fully restored here on Audiogon fairly often.
