Fair enough, pardon the cranky attitude of the originl post.  Now, about "the courage to change the things I can"...
Would any upgrade available increase the available output on the T6 phono only pre?  What may be at work here is the fact that, due to a move, I've had to go with much longer pre-to-amp interconnects (but then again, they're a VERY low cap/low resistance design, so...?).
The cart is a high output (4.mv?) moving iron from Grados Reference line, so it ain't like I've suddenly swapped in a micro-micro volt MC or something.  And I don't think the tubes come into play here (NOS Mazdas), or do they?
Thanks
(the real issue may be simply that I HATE shipping stuff away 

 )
