when overdubbing, the placement in time of the audio is not accurate with third party devices in pro tools hd [or le].
the ability of the software to compensate for the hardware's a to d and d to a conversion delays is a significant feature of pro tools hd that does not exist in pro tools le. it only works when using digidesign interfaces. in the i/o setup window, see: "compensate for input delays after record pass", and "compensate for output delays after record pass".
trying to use "high-end" interfaces for tracking and overdubbing is not a good strategy. those types of converters generally have significantly more latency than the digi 192, because they typically rely on a lot of dsp for their various tricks and turns.
likewise, trying to use "high-end" interfaces with pro tools le is subject to the same issues.
logic audio has a feature that allows a "recording delay" parameter to be specified. however, it is in milleseconds, and not sample accurate.
it appears that pro tools hd, using a digidesign interface, may be the only solution that handles converter delays accurately, and that goes to the timing and feel of the music, which is more important than tiny differences in converter quality.
overall, it appears that a lot of people dislike the digidesign converters because it is trendy to talk that way.
in their defense, they are using what is arguably the best chip available, and they have it working with a good clock, and in an array, and with real good latency figures, and they have the hd system designed to correct for what little latency there is.
on the other hand, the fact that digidesign does not allow a user-definable setting to accommodate third-party interfaces would appear to be bad business ethics.
i actually like the 192. i think once you reach the quality of such converters differences are really minimal, especially for musical program that is going to be cut down to 44.1/16 anyways.
i prefer lynx primarily for the value, second factor was the quality. i believe the digi192, apogee adx and lynx aurora are all on the same level. it just so happened that i lucked out and preferred the quality of the lynx over these other 2 units anyways. and i still saved a decent amount of money over the apogee stuff.
to the op: I understand you have a budget but I would use some of that money towards other things rather than going full HD3, especially if you say you're getting alogn fine with a MP toolkit and 002. Get a nice summing box with an HD2 setup and some lynx converters or whichever your tastes prefer. use the rest of the budget to get some TDM plugs, you'll be fine. my .02 !
