The measured non-linear harmonic and intermodulation distortion produced by the current playback processing tends to be less noticeable on music that sounds nicely spread out and with a good sense of space and dynamics. With dynamic minimal techno, world music, or old funk it’s not as objectionable as, say, with tech trance, shoegazer, industrial, or commercial EDM where it’s pretty noticeable back-to-back with Pioneer gear.
Rather than make this super complicated with some kind of flow chart…
If you 1) play exclusively more dynamic, sparse music, 2) through an analog mixer, 3) and always keep keylock on without intentionally moving back to zero pitch during the track, I think there is a low likelihood you would be dissatisfied by the Prime player sound even as it currently is prior to assumed future firmware improvements.
If you 1) play more dynamically-compressed, dense music or 2) through a hyper-revealing top digital mixer or 3) at least occasionally turn keylock off or often return to zero pitch with it on, then there’s a chance Prime’s sound would be a letdown… especially if you have Pioneer to compare it to.
If you’re in the latter camp, I’d recommend waiting to jump on Prime until updates resolve the sound issues.
If you’re somewhere in between those two camps, it’s hard to say how you’ll feel about it. In that case, you might want to extensively demo first.
Though it would be a smart benchmark to use and goal for InMusic, I don’t think bit-perfect is even necessarily what Prime has to be able to achieve at zero pitch, as VDJ, Deckadance, and Traktor seem to have no issues with decent base audio processing and good key correction and none of them are ever bit-perfect.
Pioneer’s trouble-free & rapid link (with memory of where you were), their consistent functioning (history and next track always work), and their minimalist audio processing are all laudable and unmatched anywhere in the industry right now. And, well, Pioneer also haven’t been dropping prices on their flagships and undermining early adopters with quite-as-grossly-cannibalizing products like InMusic has, either, which might damage Prime’s long-term cred in that regard, too. To be unbiased I need to give Pioneer props on all this when it’s due.
