On and off, but it is the SL-1200GR that sits permanently in my system. My feeling is that the KD-990 is possibly a very tiny bit better in terms of musical insight, even if I use the same tonearm to compare both (my Phonomac serviced FR-64S fits both decks). The GR is such a handly little thing that does not demand much space, and it’s quite attractive too - the KD-990 is not exactly ugly, but it’s much bigger.
If we are talking about unmodified decks, the KD-990 would be miles ahead of the new SL-1200G and GR, but only because those decks have pretty indifferent tonearms and the stock Kenwood arm is way better than it looks; however I would point out that the KD-990’s plinth is largely cosmetic and is poorly decoupled from the alloy chassis, and that’s probably why I feel the deck is better run ‘naked’. I think the new Technics decks’ direct drive motors are pretty much on par with the KD-990’s but the KD-990’s exotic cast alloy chassis does make it very stiff and quite special. The Kenwood was an expensive turntable in its day and would cost a small fortune to make now.
