I own the Quarttro. I started with the original box. That was a joke;don't buy one. The cable would fall out of the box and fry the module inside. I sent mine in at least 3 times and got bad advice. They upgraded me to their second gen. box (called X);free. Still the same problem. Fastforward to about a year ago,they allowed me to purchase the Quattro for 300, (I think it retails for 1200). Finally a better mouse trap.This box has bnc's and tight fitting connector pins. I feel the sound isn't quite as good---but, it could be because the box required burn-in.On each ocasion I tried the "with, and without" I could hear no dif.---On the older boxes the with and without were dramatic to say the least.
In the end if I had to start all over I would never bought these cables. I have 10k in SR cables. I feel there is as good, without the hassle. I have only read that their box is better than their mpc's.---I have also read about the older boxes being better than the Quattro---But, Mom said don't believe every thing you read.
One more thing: When I changed power cords on the box from the master coupler to the Ref master cord BIG DIF. as well.
To recap, more money, counting the box and a great cord for it, more complication with the extra wires going to the box--- I guess you can tell I don't work for S.R..
