1987 Sansui AU-X701 "Vintage Series" (100W RMS).
This amp is one super fine sounding amplifier. Saw one for sale about 6 months ago for $94! That won't happen again...usual price in USA would be $200-$250, but it's worth more. I was watching the auction but didn't watch the end. My mistake. $94 was a give-a-way. I would of bought it for $150.
The X701 is really a fine sounding and quality build amp. They don't come up for sale very often so you do have to be patient and wait for one to pop-up. It's big brother is the AU-X901 (130W RMS) and these rarely ever come up for sale in USA and when they do they sell for about $700. Even more. In Europe they sell for $1300-$1500 (+).
You sure could do a lot worse than an X701! It would be a fine amp for anyone. It's really a rebadged Sansui domestic alpha. So that should give you some idea of what I'm talking about.
I have the X901 and it's really nice. It's ended my amp search, I'm done, this is the amp for me. I'm sure the X701 would 'fit the bill' nicely. Note: there were other amps in this series like the X-501 (which folks like), X-301, X201, etc...but the X901 and X701 are the only real 'alpha' amps, I believe.
The other nice thing is these amps were made in 1987! They are not that old...yet. And they were quality builds so no restoration is required. Caps are fine.
Don't laugh but...Sony made some really nice amps too in 1987-1989 too, very heavy amplifiers, the real thing. Not the quality of build of the X701, and don't sound as wonderful, but they still sounded really good and are bulletproof. Bought one new for my wife back in 1989. It functions and sounds as good as the day I bought it. It's a nice Mid-Fi amp. I know I'd never sell it. Think it cost me $400 back in '89. Model STR-DE305. It's nice. Listened to it for 9 months waiting to find a X901.
Good Luck!
