Another cable question

Hard to be positive of the outcome without trying, but some rules of thumb probably apply. How is your tonal balance? Do you think you are on the cusp of having the sound become a bit analytical? Would a cooler presentation be bad?… not being as warm and musical? Most likely in two steps your system will more detailed but slightly less fleshed out… but cu/ag and more so ag would likely improve detail and imaging a bit. 
 

Best to try. Have you experimented with power cords? They can make a difference as well… typically to the same sonic characteristics as interconnects.

OP, Thank you for your response. This is really helpful. 
 

Wire changes are a very important part of tuning a system. But it is the last nuance. It is critical that the components get you 95% there. So, I recommend looking carefully at your vinyl signal chain: cartridge, arm, turntable, and phonostage. Let me take a bit of a side trip.

Vinyl and digital can sound the same. In my system, I achieved parody two or three years ago (finally!). If you had infinite budget, vinyl wins… in detail, natural sound and musicality. In general, in systems less than $50K it is easier to have vinyl exceed sound quality than digital. Above this, parody for about the same money, above $200K vinyl pulls ahead again.

So, your analog side has a problem. This is where I would look. I’ll have to go back and look at your system. It is most likely your cartridge or phono stage. Likely the second. Phono stages are critical and need to be of the highest caliber to get the most out of your analog rig. I would not do major investments in interconnects until your signal chain is perfect… then look at wires.
