re: STR-AV720

I bought this receiver new in 1991 to replace a Pioneer that had gotten fried by a lightening strike. Almost 30 years later, I still use this receiver and the Jensen loudspeakers I had before getting the Sony, and they still sound good to me. I have seldom used the surround sound feature, as I only use it for music and not for watching movies. After all these years, I have wondered if the electronics are in need of a freshening, but everything still works, I don’t hear any static or scratchiness from the controls, and the sound seems clean to me. I was surprised to find that the going price now for this model is about $100, more or less, so it might not make financial sense to even have the thing restored. By the way, the actual power rating for this receiver is 80 watts per channel RMS from two main L-R channels, from 20 Hz to 20,000 Hz and at noted THD, not the 110 watts listed above.

Older, less powerful receivers fetch higher prices than this Sony. I read that one knock against this vintage of equipment is that the faceplates, knobs and buttons are made of plastic rather than metal. Also, the cabinet of my Sony is thin metal instead of something heavier or a wood cabinet such as walnut. I agree that some older equipment looks very nice. But to me the receiver is it’s guts rather than it’s appearance, and I have been satisfied with the sound performance all these years. I don’t have HDMI, WiFi or Bluetooth, which would be nice, but I have read that some audiophiles think the old stereo equipment has better sound than the new AV receivers. I can still play my large flat panel television through my stereo system via an optical cable from the TV plugged into a small converter that allows the sound to be delivered to the receiver’s RCA auxiliary jacks. I don’t use it much, but it is there if I want it. I have read that I can use the TV features to stream on-line music through my stereo. I haven’t tried that yet.

If someone wanted a nice stereo receiver for little money, I would recommend that they get this Sony receiver and let other people worry about chasing snob appeal or making an investment. It even has a remote control, if you can find one with it. Then, you have money left to spend to upgrade your speakers, which have the most impact upon the sound quality anyway (I was thinking of upgrading my speakers to Magnipan or B & W). My humble opinion.
