Speaker cables with good timbre

Indeed a lot of choices out there. I used the Morrow cables from the 3 to the 7, very good cables. I've also used Silnote, Siltech 330 and 550, Bogdan Ghost, transparent Plus, MAC Cu , some Chinese clones and even the Micca cables recommended by Mr. Hoffman. I'm sure i'm forgetting some of them. I will be trying some new cables after i come back from a Thanksgiving trip. I'll post my experiences then.   

Silversmith Fideliums are excellent. And affordable.

I replaced $6K cables that are now relatively junk.

Truth of timbre?  Cables have no timbre, truthful or otherwise.  All dependent on cable synergy with source component and loudspeakers.

+1 on the Acoustic Zen Hologram. They don't add or take away anything from the soundstage. I'm also using Acoustic Zen speakers so they make all the more sense.

Cable preferences are like assholes -- everyone has one!  Throwing my hat into the ring here, I have used a full loom of Morrow "7" cables, MA-7 IC,s SP-Speaker cables.  I liked them and they were a good value for the money.  However, I then went to Shunyata Alpha v1 speaker cables and then Shunyata Sigma v.1 speaker cables, and they are just fantastic in my system.  I have a full loom of Shunyata power cables, Sigma IC's and a Shunyata Everest power conditioner, so I am a fan boy.  In my system and to my ears, they are exactly what you are looking for.  Of course, cables are dependent on a lot of different factors relating to your components, so YMMV.  But for me, Shunyata is great and highly recommended, as is the Everest!
