My first excursion into tube rolling. Today I took delivery of a set of Miniwatt Dario 7308's, plugged 'em into my Isabella/DAC. I also have a standard pair of 70.2's driving Zu Definition 2 speakers.
I admit I was a little skeptical that new tubes would make much difference, but I am blown away. From the very first track, it is a night and day difference over the stock JJ tubes. Far better bass response, much more "alive" mid-range, the sound just leaps out and fills the room very satisfyingly. All parts of the spectrum (that my ears can hear) are represented clearly, cleanly, fully, deeply.
Fortunately I got an extra pair of these, waiting in the wings for my LFP upgrade for the 70.2's. I can't wait!
Thank you Red Wine.
