To judge the value and usefulness of my opinion, one must understand where Im coming from. I needed an amplifier which was both affordable (Im cheap that way!) and which would accommodate multiple devices. Specifically, I needed to connect and be able to select among a TEAC reeltoreel tape deck, a Panasonic cassette tape deck, a Thorens turntable (yes, I still play vinyl), and a CD player. These beautiful antiques (well, all but the CD player) have been with me since the 1970s and I was in no way ready to give them up, but my National Panasonic quadraphonic receiver finally gave up its electronic ghost. It had been playing only stereo for years anyway, and no new media come in fourchannel quadraphonic format, so a stereo amplifier was all I needed. Nor did I still use the radio tuner in my old receiver, so the absence of that was not a problem. What did I give up (besides the third and fourth sound channels that no one uses any longer anyway) The old receiver had a beautiful hardwood case the new Pyle Pro amplifier has a fairly thin metal case. The old unit had beautifully chromed metal push buttons and knobs the new one has black plastic ones. The old unit allowed me to adjust the volume on each output channel individually the Pyle Pro does not. The old one had sliding controls to help achieve the best possible sound balance in a given room and with a given speaker configuration the Pyle Pro does not. The old one had a "Loudness" button to enhance sound quality when played at very low levels the Pyle Pro does not. The old one had a knob that could swap channels from one speaker to another (left to right, back to front, etc.) the Pyle Pro does not. For use in a typical living room with a typical listener, however, few of the bells and whistles on the old National Panasonic receiver were ever used. The level of finesse that they were designed to achieve exceeds that of the nonaudiophile, and I dont really miss them. The only adjustment that I wish the Pyle Pro had wo
