I thought I was going to upgrade my audio/video equipment last year. I’m happy with the video part but I still prefer listening to my old stereo from 1972. It is – Pioneer Sx-727 receiver, Pioneer CSA-700 speakers, Dual 1218 turntable. When I crank my new stuff up it doesn’t come close to the old stuff that drives the music right into you and fills you up with it without distorting. I want to achieve that with my new stuff if it’s possible and maybe you folks can tell me what I did wrong and how I can fix it. Here’s a list of the new stuff and some of the specs which have little meaning to me -
A/V Receiver - Onkyo TX-NR3007
Power Output -
Front L/R 140 W + 140 W (8 ohms, 20 Hz–20 kHz, 0.05%, 2 channels driven, FTC)

I’d rather not start all over and hope there is a simple not to expensive solution. Any criticism, advice and suggestions will be immensely appreciated.
Thanks…Stu
