Definitely my Realistic SA-1001 35 wpc Integrated Amp. I bought this on a whim from a blowout table at a Radio Shack in about 1991. Well under 100 bucks. I was going to put it in the garage and forget about it. As time went on, I realized what a great amplifier this really is. The amp is built like a tank with a great wooden case. Easy to service, well designed circuitry and well structured. I have recapped it about 5 years ago and have it set up in my living room with a Pioneer PL-514 table and Optimus 10 Speakers. I am currently using an old Technics Tuner but randomly check Fleabay for a matching Realistic Tuner. In other residences I have a Yamaha CA-810 system and a McIntosh MA6900 System, but I have to tell you, the Realistic SA-1001 System holds its own very nicely. I'm super impressed. I really am amazed at this amplifier. It has definitely surprised me the most of any gear I have ever purchased.
