Bumping up this old thread as I recently bought an FM-only Kenwood KT-1100SD tuner. This was their TOTL model around 1985-86, and was their first serious high-end digitally synthesised tuner. It has some very nice design features such as a balanced mixer for excellent strong signal handling, an analogue multiplier stereo decoder, 4 IF bandwidth settings (the only Kenwood tuner with this feature AFAIK), and also an optical encoder in the large rotary tuning knob, which means it won't wear out
Mine has been modified with narrower filters in the narrow IF bandwith settings, had 3 NiCad batteries for retention of presets, and a re-alignment.
It really is a superb tuner. The sensitivity of this thing is stunning, and it even beats the famous Sony XDR-F1HD in this respect. It is, I think, the most sensitive tuner I've ever used, and, thanks to those narrower filters has superb selectivity in the 'super narrow' setting. The sound quality is also very good. At first I didn't think it sounded as good as my Yamaha T-85, but I think it just has a bit of a different character. This is my first Kenwood tuner and I am very impressed!
I hope to get further modifications done, with a wider bandwidth in the super wide setting but even sharper selection in the super narrow. There are also quite a lot of mods that can be done to bring the audio quality right up there with the very best tuners out there.
The thought of an audiophile/serious DX tuner in one box sounds very appealing to me...
