Hi all....I just upgraded from a NAD C320BEE integrated amp to a Sunfire Symphonic Reference amp/pre amp stack. I kept the NAD C521BEE cdp and am looking for a tuner to go with the system. The unit is powering a pair of Energy Audissey 5+2's. I guess the logical tuner would be the NAD C422, but the more I read about other tuners, the more confused I get. I'd like to keep the price at or below $500 and am looking for advice from you much more informed guys and gals. I have access to a few "hi-end" audio stores and at home tryouts are probably within my reach, but am looking to narrow the field a bit. I truly don't know much (if anything) about tuners and that's why I'm asking for help. I have a '77 Pioneer SX 1250 receiver that pulls in alot of stations with just a passive indoor antenna, and a Yamaha 5540 receiver (for HT) that gets very few stations with the same antenna, so I guess I'm looking for a tuner able to pull in weak signals (whatever that may be called). I also have a powered indoor antenna that I used with the Pioneer, but it didn't seem to work any better than the passive one, so it sits on a closet shelf (ready to be used if needed). Any opinions and/or suggestions would be greatly appreciated. Please pardon my ignorance and thank you in advance....Jack
