My favorite integrated amp has so much sentimental value to it that it became special, perhaps just because of its sentimental circumstances. It was the amp given me by a very close, long time friend of mine just before he died (40 years is a long time). I was in the store when he bought it, I heard him get cussed mad when it 'misbehaved,' and he longlingly passed it on to me when he knew his time was up. It was the Marantz 1180DC. What a heavy, DC coupled, extra powered amp --- I would say one of the best Marantz ever put out, excepting its tendency to unexpectedly crap out on one channel --- then, into the shop, repaired, back home, only to have it return to the shop a few months later. But when it was perfect, it was perfect. That's my favorite ---- for many reasons --- hooked up to a pair of 1980 Klipsch Heresys.
