Memory Player64S or YFS music servers


Anybody heard or own either of these two servers- Memory Player64S or the YFS Reference-3?
They appear to have superior attributes- especially ultra low jitter.
Both are fairly pricey but can be configured as required by custom order.

Two good friends and audiophiles that I respect very much have the Memory Player; I've heard the units and they are extremely impressive in terms of usability, flexibility and the output audio quality.....send me a mail message via Audiogon and we can discuss more details regarding what I heard.
Zephyr! Thanks for the response. Very interested in knowing more about the Memory Player 64.
