Kimber Kable 8tc V.S. 12tc

I have used Rhodium plating on Loudspeaker terminals as well as power cord plugs, I would much rather used Gold plating,the Rhodium tilts up
The frequency and has a bit of glare or edge IMO. The Silver,or Gold
WBT next gen ,or other WBT model is far better in every way then Kimbers post master connections.

I never really had a problem with the physical design of the Postmasters. My concern was more that the rhodium plating or "kimber ultraplate" that they use on them was contributing in a negative way to sound quality and possibly responsible for the slight edge and glare that I experienced. I thought they actually made very good contact, at least in my system, and I'm not a fan of overtightening any connections. I used them for 20 years with no problems.

My only experience with WBT connectors is with their locking RCA's and I was not a fan of those either. In RCA's my preference would be for the higher quality Vampires followed by Eichmann Bullet Plugs, although the latter is a bit of a finicky product.

I've run Kimber 8TC for about 20 years and, on a lark at the beginning of the year bought some Mogami 3103 to experiment with. It can be purchased for about $2.50 ft. and I had it terminated with high quality Vampire copper based spades. The 8TC was terminated with Kimber Postmaster spades and I always had my doubts about them sonically, although I think the physical design is quite good.

In any event, I ended up selling the 8TC and pocketing about $175 overall. The Mogami sounded more natural overall, less hi-fi, the 8TC exhibiting a bit of "glare" and edge by comparison, although some might argue it had the upper hand in terms of "air" and imaging.

The Mogami is very good and a bargain.

Both sets of cables were cryoed and burned in on a Nordost cable cooker.

I just spoke to Kimber about this very subject. I was told unless a person has speakers with large woofers which need the control that heavy gauge speaker cable brings to bass frequencies, the two will sound the same.
