Vfet / SIT Amplifiers

The "bias" must be lowered to 45mv for the ta-4650 and 55mv for the ta-5650.

You meant the ta-E88, not the N88 ?
I speak the preamp E88, i preferred my old 700c, that's a question of preference...
But i prefer again the valve preamp with Sony V-fet, this combo is fantastic!

Enjoying the SIT3 with my Daedalus Athena 95.5DB sensitive speakers. Currently using the Pass XP22 preamp which is kept at the upper range of the volume. I have no issues with low level listening and can crank it up with volume to spare.
Still always listening below unity gain

@sonetduo,

Cheers for that, but I have a bloke who serviced my B-3s and he seems very capable. He's going to enjoy working on the Sansui as well :)

BTW, there is also Yamaha C-1 on my wishlist, do you have any experience with that?

It seems to me the C-1 is the only V-fet preamp, it's exact?
