Umm yes, Ecclesiastes. It seems that a lot of people were using external DACs & the word clock in on the TP back in the day, although no-one seems to have conducted any kind of rigorous testing of the ABX kind. It was interesting to find Sean Adams description of how he derived the quoted measurements for the TP. There didn't appear to be much consensus amongst the earlier posters as to which kind of lab measurements would be useful in the context of external DACs and digital connections... If you follow the relevant scientific argument that a DAC can only have 4 kinds of technical problems, all of which are readily measurable and for whom we know quite a bit about the audible thresholds... I believe that your position on this remains that it shouldn't make an audible difference because the TP's internal jitter is low enough to be inaudible & similarly that its in-built DAC is good enough to be indistinguishable from an external DAC in terms of discernible audible differences in a domestic listening environment with real ears, despite the possibility that minute measurable differences might be detected in lab testing. That's if I've understood your "reliable subjectivist" concept correctly. Please put me right if I've got any of this wrong, I'm not précising your early statements in my own words to irritate you but simply to ensure that I've fully got your drift. Confirmed. The TP's internal DAC was tested pretty comprehensively by Archimago in his blog. If I ever get around to writing that article about understanding technical measurements in terms of sound quality, the executive summary can be expected to say that the TP is vast overkill. Of course people say they sound different, but as you say good listening tests confirming that are harder to find than rooster teeth. There are 400 or more different makes and models of audio DACs, each selling to Audiophiles on the grounds of "Better sound". Technically, there aren't that many significantly different designs. The vast majority are based on less than 20 different DAC chips with just a few using proprietary parts. Almost all of those chips are very good and can't be logically expected to audibly change the sound of music conveyed by the analog signals they output. People hoot and holler about differences in power supplies and buffers, but they are even less likely to affect sound quality. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=71464
