Interconnect Cables for Pre-and Power amp


Hi, I’m searching for a pair of interconnect cables connection my pre-amp (Ayre K-1xe) and power-amps (Pass Labs XA30.5) – both Solid State. FYI, the speakers are a pair of Harbeth C7-es3.

Preferably, I’d get the Balanced interconnect cables to get the full potentials of these amps. What would you recommend for mid-end/used cables (brands, models, etc)? What’s the typical lengths of the cables – 1.5m or 2m?

My choices of music are mostly vocals, jazz, pop songs, symphony, chamber and some blues and rock(no heavy metal or other modern music types). I look for cables that deliver extended highs, natural/full-body mid-range and dynamic bass with excellent imaging and soundstages.

Thank you for your recommendations.

When Silver reaches an all time record high,
who will scrap their beloved cables??
Rodriguez is one of the best cartoonist out there.
He also has a wickedly dark side as well.
I agree with Bo1972, what he writes is right. I use Sky all over and also have Cheetah cables. In a good System you can hear the difference at once (Sky has a wider frequency reproduction with more body overall). silver has the best information transfer possible (AES standards).
Silver gives you simply the most information, when someone does not like it, then the reason for it is somewhere else.
I agree, with some components you can't use silver because it will sound harsh, thin, analytic but that's the sound from the units, not from the transfer medium.
AQ sky also has CARBON-BASED 5-LAYER NOISE-DISSIPATION SYSTEM Cheetah does not.
I had a pair of Sky that Cable Company lent me. I have very revealing equipment but I couldn't hear the difference between the 2. Here's what you get going from 36v Cheetah to Sky (Everything else is identical): 72v dbs, slightly different xlr connectors and 50% more air.
