Marakanetz, my amp has 47K input impedance and my sony book says 2 Vrms ( at 50 kilohms ) analog out. I have never used a passive pre before. Don't know if it is the speakers or the sony but the amp does not sound bright at all. I will do a search on some of your ideas. I have never heard any Placcette gear.
Help me with preamp choice.
I am breaking up my large hometheater system. I am just about done with a new room I have added on to my home.I have not had a stand alone two channel system in years.I like all kinds of music. The only equipment I will be takeing to the new room will be my amp,cd player and my main speakers. ( krell ksa 250, sony xa777 and vmps supertower R's ) My cables are harmonic tech interconnects and acustic zen on the speakers. My new room is 27 feet wide 25 feet deep with 10 foot height. I would like to buy used around $1500. Any type of preamp would be considered as long as you thought it would mate well with my amp.
