Hey Coen, I'd very much like to hear your impressions. You could p.m. your thoughts if you'd rather not post them on the form. Thanks.

Michael, looks like a really interesting build. Will your PSU run off a 12 volt battery or some sort of a wall wart? Just wondering.

Tried W8 yesterday with my bnc interconnects. The sound was good but not as  tonally balanced as W7. With W8, kick drums sounded incredible but voices had a bit too much mid range emphasis, or were a bit congested compared to W7. If this is the result of W7 distortion, then I guess I'm a distortion freak, or perhaps a distorted freak.....maybe a little bit of both. 

I'll give the Lindy a try but am wondering about the adapter you tried that was harsh. Was it plated with nickel, silver or both? Most are just nickel plated. The ones I've been using have silver plated contact with a nickel plated body. They have no harshness and provide a "wall of sound" too.

Whoa! My bad. I just assumed such a crazy spelling had to be an Indian word. Thanks for the deep analysis, learn something new every day.

 After my above post this morning I went for my 6 mile jog along the Shuylkill (American Indian name--no one really knows how to say it) River. As I ran, it occurred to me that I really shouldn't be offering your equipment for others to borrow! By your reply I see you didn't take offence.  Thanks!

Given Joachim and Mani's reports on their RG 223 coax (solid copper, silver coated center conductor)I ordered a pair too from Pasternak here in the US. The sound is very "nice and polite,"  no HF hash and a big detailed soundstage, but it doesn't come close to the sound of "real music in the room" that I get with the L-Com RG 142 (solid copper, silver coated center conductor). The L-Com cable is quite remarkable regarding  realism and musicality: pretty much everything I play sounds like a live performance. Last night Amad Jamal, Rossiter Road, came to life as soon as I swapped the 223 out for the 142. Listened to the entire album which I rarely do. Compared to the 223's the 142's provide about 25% more information in every frequency range.

Joachim or Mani you should ask to borrow Peters L-Com RG 142's, the ones he listened too for a few minutes and thought they could never sound good, let them burn in for no less than a hundred hours, and compare them to your 223's. Let me know if I've lost my mind.

Perhaps one reason why the 142's sound so good here is that I am using W7. Given my experience with W8-- HF's are just too much and out of control--I cannot imagine the the 142's would sound very good on W8. Maybe this weekend I'll give it a try. Lastly, I also ordered some military spec, solid copper, silver-coated center conductor, RG 142's from Amphenal. They sound very similar to the L-Comm cable but they lack the realism of the L-Com's.

Hey VJ, I assume a US tour too? I have a 6' YFS v4 data only. Would love to see if there is a difference with about a 3' "reference" version of the YFS cable.  Let me know and thanks so much for putting this together!

Hey Juan here's a bundh of bnc/xlr adapters: http://www.fullcompass.com/category/BNC-To-XLR-Adapters.html

Right now I'm using a bnc/rca adapter and it's worked well.

This is why I keep asking you guys about your cable impressions. Adding the bnc cable to my system revolutionized the sound. I had no idea how much upper mid and higher frequencies I was loosing with my prior solid core silver RCA cable. The sound here, for my modest system, is so good now I'm having a hard time imagining that the NOS1a upgrade will be a significant change. However, the consensus here is so clear that the "a" upgrade is significantly better that I'll be sending my dac to Peter relatively soon. Now, being a bit of a PITA I'm trying to gauge whether I should include the "75b" in the upgrade. Thanks for your patience, especially you Peter. 

Joachim, am wondering what your impression of Peter's cable, the Blaxius, has been compared to your RG 223? Did you upgrade to the "75b"version of the NOS1a? I received a RG 223 cable yesterday and "out of the box" it sounded as good as my RG 142. Am letting it burn in a few days before any serious listening. Thanks

Brian

For further reading on USB cables in this forum, and the YFS data only cable in particular, look here, page 4. Not everyone who tried to replicate a data only cable had good results:

Thanks Mani for taking the time to do this and for giving us your impressions.

Okay, thanks guys. Sorry if I'm being a PITA!

Thanks Mani. I assume the center conductor of your H & S cable is the solid silver-coated copper version. Given the change in the NOS1a-75b version of the NOS1, would it be possible for you to compare your H & S cable using your "standard" NOS1a DAC to your Blaxius cable using the 75b version of the NOS1a? Hope that's not too much trouble!
