Re: Oh, really?

Well, i did say *various* reasons (including contractual).

And you should know that i don't necessarily give out data even over private email, since we had an email exchange on this.

But i'm happy to share some types of information, and I can always suggest how that information could be independently derived. For example, I have already suggested to you that you could in fact measure how different transports affect jitter. That's data you can (relatively easily) collect and analyse for yourself. Unfortunately, I can't share data that someone else has collected, partly because i no longer have it with me and it's not my data anyway.

For example, i noticed in one of your replies to Alex you said: "This is exactly why the transport mechanism itself has virtually no impact on jitter. Every CD player ever made has a buffer for the bitstream coming off of the disc. The data is clocked out of this buffer by the master clock (or some derivative thereof)."

What I can suggest is that: if you actually take the trouble to measure jitter of the bitstream prior to the buffer, and after the buffer, you may find that the buffer does reduce jitter, but doesn't eliminate it completely. In fact, there is still significant jitter in the bitstream coming out of the buffer. Why? I think you will find the answer fascinating. In fact, the transport is one the major causes of jitter for many reasons (hence the difficulty for most players to get below 150ps in terms of jitter). The PLL that is used to regulate the spin rate of the disc (CD only - DVD is buffered) is one of the reasons, as it can directly (and indirectly) affect jitter. But there are also other reasons.

I'm sorry that you want to make every conversation between us an adversarial conversation. As I've said before, I am happy to share information with you, if you ask nicely and without malicious intent. What you do with that information is entirely up to you. You can ignore it, disbelieve it, or perhaps you can use it to improve your players. After all, it's the end results that matter - and I've gently pointed to you that at least in terms of jitter there seems to be room for improvement in your players.
