Trying to find/identify a very specific step up transformer

Hi Everyone,
A few months ago there was a review in Stereophile for a very affordable, punch-above-its-weight SUT that was made somewhere in (Western?) Europe. I bookmarked the article on my phone but then my phone died soon after and I lost the link. I'm now trying to rediscover the company and thought that this community would be the ideal place for me to ask.
Along those lines, once it's been identified, if any of you fine people have any actual experience with the product, I would love your thoughts.
Thanks!
