    since the 700 I've got to admit I've just been accepting what I got, & haven't really considered other options, as much as I love my h700 optical setup, I do think my systems were warmer & more natural when I used to run a f1 status head, line driven into a pair of eqt's....

    I always felt a slightly less rich & true sound was the tradeoff for the convienience of the h700... up until now it's been an acceptable tradeoff, for the convinences I get, but I'm thinking that the solution your looking at is more akin to what I'm more used to in real high end car audio..

    what are you looking to use for eq tunning?

    I just talked to him a bit more and he's going to switch out the cap with some blackgate caps. so that should just make it all the better! :-D

    the usb v. optical comparison. the usb dac uses a non oversampled signal, there is no upconversion or anything like that so it should be a pure signal. the usb dac that douglas has designed probably will have a higher output voltage then the h701 as well.


    as far as the tests and tunning, i will start another thread on how to set up this comparison. please chime in

    it's on its way! douglas sent me a confirmation email that the dac was shipped out today. i'll give you initial impressions hopefully this weekend or next and then later when i get the install completed i'll give some in car feedback

    ahhhh, that's always the BEST reference... I usually advise wanna be tuners to spend some time listening to there source material with a high quality set of headphones on a high quality reference system, to know what there ideally shooting for to begin with.....

    also anxiously awaiting these results, I've been kicking around the idea of getting the newer f1 status processor, like the 700, but much more advanced & computer intergration too, but I'm afraid this may still suffer compared to what your talking about, this is very dependant on what your going to use for 1/3 octave tunning though.....

    yeah any help with the eq'ing and setup of the test would be great. i think i may have to load up winamp and look into the tuning plug-ins

    let us know what you find on the plug ins.

    Re the F1 piece: My only reason for not going that route now turbo is that you must use the cd player with it, correct?

    honestly, I'm not to sure.. I have a whole alpine system in my car, so I've never been to concerned with that... I know the 900 would work for me, the new new one I'm not to sure...



    as far as the eq, yeah, see that's what I would expect to be an issue, if you clean up the audio signal to the point of a perfect clean unprocessed signal, that's all well & good, but in a car, the car itself just adds so much in the way of ruining the sound, by reflections, absorbsions & other artifacts that are introduced, that 1/3 octave tunning is 100% necissary really.... how that is handled is what will determine the actual final results.....

    I'm guessing if you ran this directly into a pair of eqt's or maybe even a pair of other high end eq's like a pair of rane's the problem would be solved, but that's so 1980's

    I did see a few threads about software eq's, never paid much attention to them though..... until now anyway....

    I am not sure that the eq'ing will be critical in this review. i'm thinking maybe raw output into the headphones to just compare what we would be working with. then after that it would be off to the car where eq'ing would be a must, but i'm not sure if that would be a fair comparison since each card would most likely need a different eq setting. hmmm maybe we could collaborate on a way to do this test scientificly.
