1st time AG'er. Cables ? ?

First off - what a phenomenal site / formum this is. Have spent several months in research to help get over the false starts and blind alleys in educating myself about this hobby (maybe a way of life to some!)

But on to the point. Began my step "over the edge" last year with purchase of Theil 2.3's. Love that sound - but grossly underpowered with a Yamaha something or other.

Just acquired used Krell KSA-250 and KRC-HR pre from Audiogon. I know - "you love 'em or hate 'em Krell" - but those Theils definately needed some kick.

Equipment is just starting to arrive - so I could really use some sage advice on cables. I am really in a knowledge blackhole as where to start. My equipment choices (I hope) will give me very clear / flat / uncompromising sound.

Any suggestions, recommendations, or enlightenment, will be greatly apprecated. Thanks in advance - and thanks to the hundreds of AG'ers that share their experiences & opinons with others.
