Ratings & Reviews
Rogue Audio Sphinx
I am not an audiophile or tube expert. But I love experimenting and thought, why not try a tube rolling. I ordered this pair and replaced the stock JJ ECC802s (not gold) ones in the new Sphinx v2. Even my "un-trained" ears can sense a difference and improvement in sound. It is more natural but packed with strength now. Imaging is improved and the air between vocals and instruments are much more lively. I would recommend these, though I have no comparison with any other tubes than the OEM ones I replaced.
