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!
