Speaker cables with good timbre

Surely the only goal you should have for cables is that they add as little as possible to the signal and not what they add to the sound.

Cardas is well known for their copper quality. I recently purchased a pair of Clear Sky X4 speaker cables. They are remarkably balanced with no particular emphasis on any frequency range. 

@audiogabby  I must say I find cable threads akin to asking what shade of blue is the sky?  Human nature says most will recommend what they are using themselves.  Then there will be dozens of different cables recommended.  They can't all be the best?  Since I don't have your room, your equipment or your ears, can I really suggest what is right for you?  But for what it's worth, try building your own set using VH Audio CHeLA Speaker cable (in bulk), now available with pure, solid OCC Copper conductors!

The CHeLA OCC speaker cable is made of 48 individually insulated 24 AWG SOLID OCC (Ohno Continuous Cast) copper conductors that are insulated with VH Audio's AirLok� dielectric. VH Audio's AirLok� dielectric is a proprietary form of foamed/cellular Fluoropolymer that has a dielectric constant of LESS than 1.5 and an extremely low dielectric absorption. The 48 OCC copper conductors are braided into VH Audio's Counter Helical Litz Array TM geometry (C.He.L.A.) around a core containing strands of unbleached cotton. This special self-shielding speaker cable geometry results in very low inductance (.011 uH*), reasonable capacitance (230 pF*), and low DCR (1.35 milliohms per foot*). Additionally, the CHeLA geometry results in more symmetrical field interaction between strands vs. conventional braided designs. Aggregate AWG for each grouping of 24 conductors is 11 AWG, and the approximate cable diameter is 3/4"  (cut and pasted).  A final benefit is the joy of building your own cables.  IMHO

  Not surprisingly, I use these in my own system.  As good as any cable I have heard and only $43 per foot.  Cheers.

Cables are so numerous that it gets pretty crazy and confusing. You can't try them all.  I don't pretend to have listened to too many, but I simplified my choice and am very happy with Morrow cables, and you just go up or down the line to suit your budget. They are very helpful and responsive, the cables are very flexible and not so thick (I switched from MIT that are garden hoses with those damn boxes, sound good but what a pain!). They're a great buy with the frequent sales and you can try em and send back if you wish. They have the characteristics you are looking for as far as sound quality is concerned. 

@dickieboy  I can second your opinion on Morrow.  I used them for years but only as interconnects.  Their Christmas sale appears to be the best of the year at 60% off.  Morrow is a bit like the airlines.  Always on sale.  A while back I needed to go to a very long set of XLRs so I drank the Kool-Aid and purchased a new brand at a much higher cost.  I can't honestly say I heard any improvement in sound over the Morrow cables.  They also give a 60 return policy if you're not happy for any reason.
