@Mijo--In my experience all drive system represent trade-offs--none are perfect but some better than others. The TE-2 approach is to extract the best of what belt, direct, and idler systems have to offer while minimizing the downsides. I think the TE-2 achieves this goal as per speed stability, accuracy and quietness of operation. The proof is in both listening and measurements. As for dodging wow and flutter if you dig a little deeper you will see that Paulo at Sempersonus has developed a very sophisticated devise called the "Shaknspin" which Michael Fremer reviewed very positively on Analogue Planet. This clearly attests to the designers commitment to strong measured performance. You can read the review here:
