IsoClean Focus SC-101 and SuperFocus speaker cable

Well, I finally ordered them. It seems that the cables were used/burned by the dealer. Sound excellent and have more midrange body as compared to the Purenote Cerulean, while the latter cables have more HF extension.

That would be a good rule of thumb.

I understand. Then they won't match my speakers with rolled-off highs!

I have owned both. They are excellent, particularly the SuperFocus and can generally be found at very attractive prices on the used market. I would note that both are warm and full with significant bloom and both have somewhat truncated top ends.
