Just out of interest tonight I went back to my old PCie USB3 card just to remind myself what the sound was like before the Paul Pang card.

I did not listen for long - there is just such a big difference right from top to bottom (and including bass) the Paul Pang card lifts my system to a completely new level. Even my cat (if I had one) could hear the difference.

There is no doubt the bass is much better via Paul Pang - it may just happen in my system (who knows?) but for sure "it don't half sound good".

I heard a really big improvement in Nicks system with the improved NOS1 USB clock upgraded - right now it is hard to believe that I can get that sort of improvement in my system because it is sounding so good now. Anyway a reference grade 24MHz clock is on its way so I should know in a few days.

A mouthwatering prospect I have to say. I can't wait but one thing I will be doing first (before upgrading the NOS1 USB clock) is to remove the clock from my stock PCie USB3 card and try the reference clock in its place just to get compare with the Paul Pang card.

Watch this space!!

Peter I did understand what you meant.

Cheers

Paul

Paul,

Plus two more here, I decided to go for two in the end one at each end of the link. If there is any headroom still in the clock set up these with luck will find it  Happy

Though the PC is a relatively easy place to tweak, the NOS1 usb clock mod is expectedly the most important for sq. I hope Peter will have a report on that (NOS2?!). 
Nick I was wondering: how do you power the NOS1 clock?

Coen hi,

Power with the test set up has been from a LiFePo4 battery with transformer decoupled signal. I'm committed to the mod and want the convenience of mains power with a really high quality clock so orders have been placed for a couple more of the clocks I currently use for my "audio clock" but in a 24mhz output. Paul and I have fingers crossed that they warrent the considerable expence. These clocks have been ordered with their own mains PSUs.

Regards,

Nick.
