Cable advice

Start with the fact that good cabling is rather expensive.

Going one brand is easier and you get a house sound if you want that.

Going mixed will get you there but that will happen with more effort and probably more money.

Whatever you do (copper, silver, stranded or solid core) experimentation is required plus a good time for the things to settle down.

At the moment I use four different brands, even by mixing metals, silver for turntable, phono and speakers, copper for all the rest and I am happy with the result.

This is particularly true if you liked the house sound of your components and therefore bought all of your components from the same manufacture. 

I personally don't think it's that important to have all cables from the same manufacturer (a "loom").  In several of my rooms I have Synergistic Research, Acoustic Zen, Wireworld, Lavricables, Nordost.  All of my systems sound great. All my powercords are Shunyata except for one which is a VooDoo.  All my power conditioners are Shunyata except for one which is Synergistic Research. My choices are driven by price - almost all of it is purchased used from Audiogon or Audiomart (US & Canada) I don't have the inclination (or budget) to  try different cables for a given piece of eqiupment.  I couldn't really really tell a difference between them anyway.  The one exception is that I like silver conductors (with an occasionalmix as in Nordost) in preference to copper - I can hear a difference there and I don't perceive them as too bright.  So, don't fret about whether you have a loom or not. 

The Kama Sutra approach is more fun.

About 25 years ago, I asked a gentleman who sells NOS tubes (an individual who most on A'Gon seem to have a lot of respect for) about mixing tube brands in a certain application.  He told me it wasn't his favorite thing, but not as bad as mixing cables.  I asked him what was wrong with that, & he told me (and I am paraphrasing) that if Cable Brand A did one sonic aspect well, but was upstream of Cable Brand B which fell short on that attribute of Cable Brand A, but did a different sonic aspect well, the positive aspect of Cable Brand A was being negated by Cable Brand B's failure to pass it on.

Anyway, that was his logic; he sells tubes so I guess he doesn't have any skin in the cable game.
