Cable for vintage Rotel tuner

Radio has about 12 dB dynamic range due to the multiband compression, limiting, and clipping done at the station. Not equal to even vinyl, though might be more enoyable due to the extra processing. Can't see the value in pricey cables here.

I agree with Steve unless you are in Europe or have a Day Sequera Tuner. The Transparent cable that is the biggest jump in quality is the Ultra Link which is in the middle of the line. Nobius starts at $800 for a meter pair.

In Europe you can hear the difference between turntable on FM but hear the FCC limits a lot and as Steve says, most stations need to compress a lot due to how far they are trying to blast the waves and conserve power.

I live in Flanders (belgium) in Europe and reception through cable isn't bad at all. I just need a cable that keeps the 'crispy' sound but adds warmth and a tad more smoothness.

Is Transparent a copper cable? Other 'copper' suggestions?

Transparent is copper but will not have sparkle or crispness. They are a little laid back in the highs. They don't cover anything up but present a concert like you are in the audience and not the director on stage.
The Nobius and FMS will do everything you are asking for in a large amount. They are hard to find because no one ever sells them unless going up in the line or getting kicked out of their house. Stay away from Nordost, they are very bright. Upper end Audioquest will be a safe choice too.
There are other good cables I am sure but am not able to think of them at the moment. Try Synergistic as well.
