Krell CAST cables...which to buy?


I want to buy new CAST cables for my all EVO system (202/402/505). I think I currently have the original type.....purchased just over 3 years ago....about 1/4" diameter?
I have read many different opinions regarding the various choices available and would like to hear the up to date buzz on what is best. Unfortunately I cannot audition any so I have to make a god faith call on this.
My feelings on the sound of my gear right now is that it lacks a certain sparkle eg...cymbals seem muted and not metallic enough. Pianos don't have that percussiveness that they really have. Sound stage seems recessed. Not that I am looking for anything too bright.
I've read some posts that suggest the Nordost MMF is to fast and thin?
Any insight would be most appreciated.
Aloha.....

Cheers...I saw your posts on the subject.
I was wondering how the Nordost cables stacked up against those?
Reading some conflicting reports.
But that's hifi right ;-)
A friend here in the UK had a set of Cast cables specially made by Synergistic Research. This replaced the the Nordost and Transparent versions. I think it was a special order. He has Krell Evo system.

SR does make a custom CAST cable with their magnetic Tricon they sayed the price was $1450 US for one meter. However not too many opinions out there on it. I only know the one person in the UK David that has the cable and all he said was that he sold the Nordost for me I'm still sitting on the fence thinking of jumping in as I'm also using the original first Krell CAST cable between 202/700cx
I have been curious about this myself. Does anyone actually know the chronological mfg. order of the CAST cables? I've seen, original, thick, thin, silver, Nordst, MMF, etc...
Which came first etc...? Anyone noticed any significant upgrade with a newer version?

I do know the order is Original Thick, Thin Silver, Nordost MMF.
Not sure when the change was made to Thin Silver as I purchased mine late 2006.
I have a call into Krell so hope to answer that question soon.
Seems like there are quite a few of us wondering about this issue.
I did call Tara and they said they would make me a set using The One cable for about $3000/meter. Way to expensive for me especially as CAST is supposed to end the need for these super high priced cables.
I'd jump into the MMF if it were not for a few posts suggesting that Nordost is not the best wire to use with Krell gear, despite that fact that it is Krell's and Dan D'Agostinos personal recommendation.
