Yes, I have ! :-)
I use to use DNM interconnects, those were fast and clean on my all tube system which is what I needed, when I went to the MG Planus I interconnects, I preferred it and thought I'd find Audio Nirvana, in fact, I was so happy with the synergy and 3D soundstage the the MG cables offered that I didn't think I would ever need to change them, but boy was I wrong?! I ordered a set of the CT1, and to my surprise, the difference was as huge as swapping a component like changing the DAC or amp for instance, the bass became solid with incredible gravity and solidity, the mids more airy and open, the top-end was also more natural yet more pristine and crystal clear, then I made the mistake to try the CT-1 Enhanced, that was even more unbelievable, what was so great about the CT-1 just got way more airy, way more clean and way more articulate with a precision that was almost sick! Let me assure you, your MG's although good, will sound like cheap and nasty cables when you get your hands on the HF cables, the price is of course way more, but the payback is ridiculous. If you can afford them, I believe your search will end there. Anything else will warrant upgrading except for the CT-1/E. I am about to upgrade my MG speaker cables and saving big time for the CT-1's, I'm suffering from what I'd like to call, PWS (premature withdrawal symptoms), believe me :-)
