Best int amp i've ever owned. After upgrading the main caps this amp becomes extremely warm , yet dynamic.



AU-888 - Refurbished Model (December 2017)

I obtained a refurbished AU-888 for a close comparison with an equally refurbished AU-999 I already own. Honestly, the differences are very, very marginal. Both came out of Sansui's 1971-2 product line touting the AU-222 and AU-555, with the AU-555A inserted in between, and continuing with the AU-666 through to AU-888 and terminating with the AU-999. As such the 888 carries the patented designs of the downstream products of the range: the simplicity of what looks like hand-wired circuit boards, the single large E-Core transformer in black square casing and the use of silicon chips. Most of this range also offers the knob for adjusting midrange.

How is the AU-888 different? For starters, it's got 20 Watts more power per channel than the 555 and 555A and that enables it to pair with any modern or vintage speaker out there without showing any strain! Additionally, it still carries the famous Sansui 'loudness' switch meant for enhancing low volume listening. For me, I seldom engage the loudness feature. The 888 never runs hot even after three hours or more of operation and drives both 3-way and 4-way speakers with ease. Match it to PHONO sources and/or CD sources via the Tape sockets and you'll be amazed it reproduces music with precision, 3D realism and what sounded to me as something close to SACD quality sound. I know this because the jazz orchestral tracks delivered the percussion 'live' to the point where I mistook the some of the sounds as coming from my neighbours' apartment - turns out the 888 was reproducing details I'd never noticed before. The familiar Sansui warmth is also evident. It is hard to tell the 888 apart from the 999. The 999 is very marginally superior because it allows ultra-precise tweaking of treble, bass and midrange whereas the 888 offers the same precision only with the midrange. You can't go wrong with either choice! It will come down to a matter of price and quality of restoration.
