Interconnect question

I have the same table. Better interconnects (Morrow 1.1) made a big difference for me in clarity.

I THINK I understand your question. So, just remember this: any information lost cannot be retrieved by better gear further upstream. IOW, the quality of cable from table to pre is probably more important than from pre to amp. Although better cable anywhere is a good thing.

I have found the interconnect between a preamp and amp can make a large difference in the sound of a system, and I think that will hold despite your TT maybe having less than optimal leads. You will be changing the nature (and probably quality) of information that is transferred from the preamp to the amp, which is very significant. I would think you'd hear a big difference in changing interconnects between your phono pre and preamp as well (possibly even a bigger difference than changing interconnects downstream), but that's not what you're asking here I guess. Personally, I'd try to change both since I've found the benefits of upgrading interconnects to be additive. The big challenge for you will be to determine what you'd like to improve and then find the interconnect that has those qualities. If you give an idea of what you're looking for, what you currently have, and how much you're looking to spend I'm sure you can get some good recommendations here. Best of luck.

I found totally opposite to Soix. Small signal domain has substantially larger demand in wire quality.
