FWIW, TAS just posted a review on one of the StromTank units yesterday. I haven’t yet read it myself but it’s on my list to get through today. You might find it interesting.
Ok, editing this post, I did read the review. While the reviewer mentions having experience with many other power solutions, he doesn’t make any comparisons against the StromTank. I wish he did! Looking past that, his experience is mimicking mine.
Perhaps what he mentions towards the end in terms of the plusher sound is where the PowerCell 14 is improving upon in terms of dynamics and current delivery. Regardless, being fortunate enough to have both on my floor is a blessing, and I don’t think I can live without either of them.
