My first amp way way back from the 1980s. Recommendation from a friend at university - loved it. Lasted a good decade before the pots got a little crackly and needed cleaning. Soft clipping and tone controls too. Unlike some of the newer NADs (and others - yes you Creek!) you could turn up the volume control to way past 12.
Now in 2019 I'm seriously wondering whether any of my subsequent 'upgrades' Naim, Magnum, and currently Creek were actually any better...
