bgross, we’re living mirror lives! I, too, purchased the Nikko stack from Tech Hifi the same year. It was advertised in Tech Hifi’s beautiful color catalog as one of their high-end solutions. It took a while to trade up to the Nikko stack (Alpha 220, Beta 20, Gamma 20), but I got there. I began a couple years prior with a Marantz 2216b (still collectible). I demoed the Nikko stack several times in the high-end sound room -- almost always with Klipsch Cornwalls. I was hooked with one listen. The Cornwalls were too expensive and too huge to fit in my childhood bedroom, so I settled for their soul brothers -- Cerwin Vega’s (HED-3000, 3-way, w/12 " woofers and horn tweeters). Teenage heaven. Led Zeppelin, The Who, AC/DC, Van Halen could all crack plaster with that setup. I still have the Philips turntable. My poor parents.
I picked up a second Alpha 220 to bi-amp a set of Snell D’s for several years. Wow. Tight, deep bass and crystal clear vocals. The imaging was second-to-none.
Eventually I also picked up the Beta 40 and Gamma 40. I must say, the Beta 40 is audibly better than the Beta 20.
About 5 years ago I finally bought a set of 1984 Klipsch Cornwalls via eBay. One owner, oiled walnut finish & mint condition. I’m living the dream. Concert hall sound in my living room.
My system is basically 35 years old and I’ve never heard a better setup. The Nikko amps are amazing -- warm, clear and quick. Apparently, they are also built to last.
If I can find nice Alpha 440, I’d pick that up for a try, too.
