What is the best FM tuner with remote tuning?

Check into Creek Audio. They have a new tuner to replace the T43, a great sounding piece . I believe it is T50.

Though I don't know the answer, I have some suggestions; look into the Meridian tuners, I suspect they have remote and also the Linn tuner(s), and I don't necessary mean their current lines, if they are still making them.

Also, I would contact Don Scott and see what current tuner he would suggest with his mods.

Fanfare FT-1A.

Not really the best tuner for DX'ing, but if you're looking
for remote capability then DX'ing is probably not your main
concern.

I have not heard a better tuner on medium/strong signals
than the FT-1A. There are certainly (a few) equals, but none
better.

Well, I have owned the Fanfare FT-1A, I thoroughly enjoyed owning it and the remote is nice, but "none better" is not accurate; I have owned a Sansui TU-717 and curruntly use a Yamaha T-2 and place both above it for performance, but they lack the remote. I do find the Fanfare visually appealing.
