Good cables for Rega Planet/Mira combo??

Look at www.interlinkhouse.com for Stealth cables, and buy as high up the line as you can. Don't assume that silver is necessarily better than copper: my present cross-wrapped copper cables beat Fineline Reference in my system. Don't assume that your Rega/Miro combo needs something special to it. A great cable will be just fine, and Stealth has them. (Sorry if this sounds arrogantly positive: I'm just trying to be relatively brief.)

I suggest some Kimber Silver streak. I had the Rega Brio and it's midrange was wonderful but somewhat a soft presentation overall. The Kimber will flesh out some of that and should make it sound very airy and detailed with good quick tight bass. IMHO.
