Warm and Wet cables?

Nothing Dirty....sorry.

I've got a system that is analytical with neutral to slightly hot treble but with deep tight bass.

On great smooth recordings (Chesky) I'm in heaven, on rolled off recordings I'm happy, on bright recordings... ouch .. A little to much.

I want to try and go for a more forgiving sound with a cable change. I think what I'm looking for is a warmer but also wetter sound without losing the tight bass.

I need 1m RCA, one 3m XLR, and an 8ft Biwire speaker cable.

I've seen mention of Harmonic Tech Truthlinks and NBS monitor series.

Any thing else?

Thanks.
