Yes, we need 3Vrms at the input for full output (about 2*60Vrms), but I mentioned 2Vrms like "desirable" input sensitivity (max. CD output). We`ll definitely need a preamp... something like "Guinevere"? P.S. how you guys solved input switching, (cheap) volume pot problems, etc.? I looked at the some commercial stepped attenuators and input switches, but the price...
