I have used MIT since the Early 90's and still use them for my Hometheater but for 2 channel, the high end Transparent have made a larger difference(Positive) than any of my components. Both MIT and Transparent do their magic in the box, if you can't hear it then you saved yourself some money, but I tried about 10 brands (Kimber,Cardas,Custom Silver(Bright), Linn,VanDenHul, Taralabs, etc) and imaging, vocals and imaging were leaps and bound better in my system with Transparent (and good with MIT).
Transparent doesn't believe in bi-wire to much, so unless your speakers really require it, make the next step up in cable and go single wire. I upgraded to Transparent Ref Jumpers for my NHT 3.3's and the difference was a minimal (not worth the cost). I have bought/used Super (stop here if you don't have the highest resolving front end otherwise you will not gain a big benifit,Ultra,Reference and now Reference XL.
The Reason I still use MIT on my hometheater is you can get unbelievable prices on high end cables new from AudioAdvisor Closeouts and the used market. But Transparent are still much better for 2 channel critical listening in the lower cables than T2,M330 of MIT.
Make you speaker cables as short as possible. Make sure the Transparent cables are used the correct direction!!!
Actually the number one tweak on my system was adding ASC Studio Traps and generic diffusers on the side.
Either Buy used and try it (make sure to do transparent from front to back) or use an excellent dealer to try the cables as this will end up saving you money and time. Also if you buy Transparent Super and up, you can always upgrade to the next level and for the retail difference of the upgraded cable!
