recording from the TTM gives very good quality as there is no D/A conversion or A/D conversion.

Matt you will hear a difference. Im recording through ortofons before you ask. I left pretty much everything in the middle. I did try to bump up a little bit on the highs. (I didn't push it because I didn't want it to clip, digital distortion sounds really bad) The main difference is it sounds a little "muddy". There isnt anything you can do about that because you are recording from vinyl which has its own artificats. Will most people notice, probably not. But it will sound more "bassy" and more like vinyl. Overall the quality is good. The only way to make it sparkle is to tweak in a program such as pro tools. You have to remember beatport gets its track from the label as a digital file. No artificats added, such as the vinyl process. The song has to be or should be re-mixed before pressing vinyl.... artifacts related to sounds is hatever"sound" is added by the media. What I mean, if your old enough to remember is like trying to record that NWA tape in 5th grade and recording it over your sisters Debbie Gibson tape and then taking that tape and recording another copy for your pal whos parents wont buy him NWA. Everytime it is record a little something is added, in this case probably hiss.
Sorry for the long answer, I'm a gear freak.....

OK, I misunderstood the question. You will hear a difference but it would be the same difference you will hear playing beatport tracks along side vinyl.

you will hear the difference between the two. You'll have to mess with the eq to get the sound you are looking for, experiment snd play them back.
