    1. Educational review. Well done. Questions: 1. Are product model names typically consistent between EU and US? On their US site, I do not see the Syncro or Synchro either as active or retired. Today only Gemini / Nova / Titan One in increasing order of performance; 2. Can one anticipate that a tool like this will improve sound qualities regardless of size or cost? If so, when would you make the purchase: anytime or after you have some post-setup time listening? 3. Would you ever place this upstream from the amp? I am guessing it depends on the amp and the impact, right? 4. With a Class D amp in play, what would be the impact on the need for one of these?
      And for Gene, for what it’s worth, I see IsoTek includes their Premier Power cable with all units. Thx in advance.

    2. This sounds like a good addition. However, something not mentioned in the review is the need for an additional power cord for each Uni used. That can easily add up to a lot of money for anyone using decent or better quality aftermarket power cords, who wants to maintain the same level.

      • Isotek sells those cables from very affordable prices on. But you can grab one lying at home if you like. We did use an EVO3 Initial (their entry level cable) between the wall socket and the Syncro and a no name power block from a DIY shop (nothing ‘audio’ grade) out of the Syncro and plugged the power cables from the Rega Planet and the Weiss into that power block.
