Oh! Well you learn something new everyday!Just misinformed thats all I guess.Anyway a pair of digital 75 ohm cables are the first thing out of my DAC(first cables RCA) to the pre and so far in they sound much less harsh alomost a tube vs transistor kinda thing happening.It takes ALOT of the digital harshness and REALLY makes the midrange very smooth.So If I was damaging something I wanted to know because if not they are diffinatly staying.I just recently gathered all the pieces I want so I am playing with cables now that everything else is dialed in the way I want it so now im playing with cables until a new piece of equipment comes along (and it will) and I have to have it.Then I have to start all over again with my base cables Ialways use when I get a new piece.So I tried the 75 ohm digital cables and WOW!!! this is one of the single most simple and noticable changes I have made in a long time.Thanks for the knowledge and if you get an itch you want to scratch just try a set of digitals and check out the diffrence it REALLY makes...Have a good one!
