Best interconnects from preamp to amps, within budget

Hi folks. This is my second post to these forums. I’m setting up my equipment again for the first time in decades. A lot has changed since then.

The first thing I did was get new surrounds on my JBL L100t woofers. Then I took one component at a time to the shop for complete inspection, repair and tweaking.

For setup, I bought a bunch of Audioquest Tower interconnects. It was the best I could come up with based upon my little bit of research and budget. I immediately noticed an audible improvement over the 30+ year old generic "patch cords" my equipment came with.

When I hooked up my preamp to the amps (bridged) I discovered I didn’t have any new interconnects that would reach that far. For now I’m using some that are at least a few years old and generic. So, what SHOULD I be using for the preamp/amps connection? I do have to stay within a modest budget, the equipment restoration isn’t cheap. If nobody laughs too hard, I could spend as much as $100-$200 for this connection. They need to be at least 8 feet long, assuming they each need to be the same length.

I have recently read that proper interconnect selection can vary widely depending on the equipment that one uses. For the record, my current system is as follows:

2 Harmon Kardon Citation 22 amplifiers, bridged together

Harman Kardon Citation 25 preamplifier

Harman Kardon Citation 23 tuner

Harman Kardon HD7600 CD player

Harman Kardon HD7400 CD player ( so the same remote doesn’t control 2 CD players)

Harman Kardon EQ8 equlaizer (Not currently in-line, to be used for goofing around with bootlegs etc)

2 Sony TC-K620 cassette decks ( need to be shopped yet )

JBL L100t speakers, until new surrounds are broken in

JBL L100t3 speakers after others are broken in

Thanks for any help with this. As always, it’s appreciated!
