Sean, I do realize that methods of measurements may vary, and that single number can't represent a jitter spectrum in any way. But thinking this way you indeed cannot compare anything. Usually all the available measurements information is pk-pk number, rarely RMS, this is all we have, and yes, we don't usually have spectrum data, but I don't think it's a good reason for eliminating comparison and evaluation, although I agree they have to be done carefully. Frankly, I would like to see SB jitter measurements as close to high-end CD transports as possible, but if we don't measure and compare how can we get there?

Exactly! seanadams Wrote: > btw if anyone has a very high-end CD player that they'd like to loan me > for a week in exchange for a free SB3, I can do some head-to-head tests > using the same measurement setup. It's important to keep in mind how many ultra expensive CD players don't measure well, so if you are to pick one for comparison, just make sure it's at least known for "low jitter level" measured this or that way. Stereophile publishes JA measurements taken on Miller jitter analyzer regularly, and it's quite interesting how pk-pk number vary between different CD transports with little correlation to price. -- 325xi ------------------------------------------------------------------------ 325xi's Profile: http://forums.slimdevices.com/member.php?userid=5661 View this thread: http://forums.slimdevices.com/showthread.php?t=25188 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
