Upgrade Interconnects/Cables or…?

Your setup is fine.

I would seek the best available  pressing of your preferred music and avoid audio forums.

No cable/tweaky add on will magically  transform it like having a dedicated room.

Firstly the MSRP of your system is irrelevant here, I just like this expression “You can’t make a silk purse out of a sows ear” Another favourite “Some tweaks for twits”  Think diminishing return, placebo, a little returnable experimenting will enlighten you not lighten your wallet. 

@kennythekey It is pleasing to see you have the idea if producing a Build Your Own Cable as an option. Substantial monies are to be saved, even when using Connectors that are known to be an upgrade to how the signal passes through them.

@kennythekey "I’m sure I can get him to suggest what to use for the whole package and maybe this might be a loom of cables."

I’d recommend trying one component cable set at a time -vs- jumping over to a full loom all at once or you really won’t know where the weak links were prior. And remember, each of your components have different wiring inside so what really constitutes an end-to-end full loom anyhow.

Btw, I run Cross, Clear, and Clear Reflections in my Cardas sets of cables and the Cross work great for speakers as long as the upstream cables are decent. If your source, pre/amp cables are limited, the downstream Cross speaker cables may seem limiting at first. I don’t find that to be the case with good upstream cables.

You can move different type cables up/down the loom to experiment and realize differences. Maybe your contact friend can kindly let you borrow & demo some cables to try on loan, and this can be super helpful in finding a right mix for you and your ears in your system. What works in one system may not work well in another fwiw.

I appreciate all the positive comments from the community, and I’m not a stranger to the vast numbers of opinions in here and out there. So far, I have not spent a dime, and my system has a fresh sound with specific improvements that I was looking for. I know my room is not perfect, so what I just gained in one area slightly took away from another. Finding a balance that suits me best is what I’m doing right now and it’s free.

At this point of my life, I’m not in experimental mode, so those types of options are out. I have monoblocks, but my speaker cables are 12’ long due to previous amplification and a different imperfect room. Yea, I can cut them down and re-terminate them. My phono cable has a loose connector that I have to keep screwing with. It’s old! So, my system isn’t quite fine in all areas. If my choice was to upgrade my line stage, I would still have to deal with those cables or live with them. I have decided to deal with them, and get a fresh set. I have a fixed budget and I’m pretty sure my dealer will work with me to get there. After all that has been said and done here, this is my most comfortable option.

Thanks, everyone. Later.
