Hi Ozzy
I have tried the Transparent line up to the Reference XL MM2, They are a nice cable deep base, solid imagining. The mm2 line is now discontinued with Gen. 5 being the new line. You are right the different line are very confusing. In the Gen. 5 line they eliminated a level to try and cut down on some of the confusion. In the mm2 line it went Reference- Reference XL-Another Reference level-then Opus. In the newer gen. 5 cables they eliminated the Reference right below the Opus. So now in the gen.5 line the Reference XL is right below the Opus. I like Transparent cables, but the big draw back for me on them , from the Ref. line up
each time you change a component you must get the cable recalibrate for that component to get the best out of it. If you have a local Transparent dealer then it makes it a little easier. If not, then you get your cable to the closes dealer to get it shipped to Transparent for recalibration. Transparent will not let you send the cable direct to them for recalibration.
Transparent makes a good cable in the Reference line or higher, but under the Reference line i think their are lots of cables that compete with them on a smaller price line.
Enjoy Pete
