1,000+ hours in and I'm still loving it! I've been running Linlai 6sn7s and KT170s. That combo hits the sweet spot for my tastes.
For a few months I was experimenting with tubes in the TRP and in the STR for rectification. The Transcend did a wonderful job of passing along the input. Changing tubes and cables the change was clear and obvious.
Is there any thing specific you are looking for?
