I have tried Transp Ref MM2 it was really good but price wise ı could not conclude a deal with the dealer :)
how was QX4 changed ref Iso?
prior to MBL s I had also antileon signature, I have tried a lot of preamps one of the best ones that it really pleased me was Ref3 so I will assume that Ref5 will be a very good match. I ghave very recently listened to all Ref system driving magico, ıt was magical, CJ is good but only SE connection makes a lttle bit shorter on using the full scale of antileon.
