My M1 fuse has been in my Tambaqui about two weeks now. I am noticing and enjoying more texture and grain to male voices, and a greater sense of realism.
I know I should pull it out and compare, but I just like listening! It arrived quickly, ordered through The Cable Co, and was even discounted based upon previous purchases (some time ago) from them. Recommend you do check 'request price' when ordering. For $270 I think this is a no brainer of a try. Happy Holidays everyone! My good buddy says 'how can a fuse that is made of a cheap strip of metal make a difference?' I said exactly! Ken
