Hey. Still new to audio equipment and amplifiers, as far as actually owning units goes. I recently got my first stand-alone amplifier, a Realistic STA-2150, equipped with equalizer, tape deck, LAB-450 turntable, a CD player and Mach Two speakers for $100 at an estate sale. Add on another $25 for re-foaming the speakers. Have been scouring the internet for information on these components to see how I did. The Mach Twos seem to be highly regarded in certain circles, but I haven't found ANY information on the STA-2150 receiver aside form what was printed in the original Radio Shack catalog in 1989. It was apparently the second most expensive receiver they put out that year, the most expensive being approximately the same thing except with a remote control. I'm assuming that means its at least modestly high quality? I was wondering if anybody owns one of these things and could possibly share opinions on the audio quality compared to other receivers/amplifiers. To my inexperienced ears it sounds decent, yet sterile somehow. Vinyl has less of this, but it is still there. Again, I would love to hear input on this unit. Thanks!
