Looking For 90% of the performane of the super expensive cables for much less money

Most agreed in another thread that tonearm cable is the most important cable in the entire system. With such equipment level you might want something really good.
What do you call " mega dollars " ? For some it is $15k pair and for others it is $1500 pair.
So I would start with tonearm cable and leave the rest as it is right now, then rewire everything. One brand approach is not always the best but it is the simplest and often a good one.
I use Purist Audio Neptune and Tchernov Audio Reference interconnects. You can read my review here. They are not inexpensive but not outrageously expensive either. This doesn't mean it would be the best choice for you, but I think you should try a few brands. Kubala Sosna is another company that comes to mind. All three that I mentioned are used or used to be used by Lamm and many Lamm owners. This tells me something.

As far as cheap cables go, Monster Cable, more length than three systems need, $20-30 per spool at the end of the previous century, still work just fine. If you do not obsess over it. They may do just fine when compared to more expensive cables, too, but I have not had a chance. It helps to have low expectations.

The new paradigm - The Anti Audiophile. Ah, the eternal quest for mediocrity. 😛

Hmmmm, could there be a recessive audiophile gene? 🤔
