Man, don't log on for a day and a lot of new posts! My comment/complaint about digital/pre-dac volume control stands. The Burr-Brown/TI PGA2310/2311 were exactly the devices I was thinking of. My Sonic Frontiers Line3 uses the Crystal Semi version, and sounds pretty good to my ears! I -have- heard and experimented with pre-dac digital volume controls, and unless you're only using them for small attenuations, they do tend to add distortion (They don't add noise per se, I don't know where that idea came from). These devices aren't dirt cheap, but they aren't unobtainium either.
As others commented, I could indeed disable the internal volume control, and use an external one, but "simpler is better". I would prefer to just run the Transporters output directly to a power amp. Why add more boxes if you don't really need them?! And given that most people feel pre-dac volume control isn't high end, why would a device claiming to be the first real high end networked audio solution employ this technique? (insert your own cynical comments here!) My hope had been to use both the transporters better DAC, and it's internal volume control, to be the center of a killer small remote system. If I have to add an external preamp for volume control, it becomes less attractive. I hadn't intended to use the Transporter to drive an external DAC, although it's ultra low jitter spec does tend to make you want to give it a try! Maybe a DAC'less Transporter? By the way, neither BNC, nor EAC/EBU connections reduce jitter significantly. It's much more to do with the drive and recovery circuitry (not to mention the jitter inherent in the SPDIF/EAC/EBU transmission format). Word clock, on the other hand, does help. -- DCtoDaylight ------------------------------------------------------------------------ DCtoDaylight's Profile: http://forums.slimdevices.com/member.php?userid=7284 View this thread: http://forums.slimdevices.com/showthread.php?t=27158 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
