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.
Perfect tube for headphone amplifier with very detailed sound
For my headphone amplifier I already tested some tubes. The best are the "Holy-Grail" NOS SIEMENS 12AU7/ECC82 long plates. Disadvantage: very expensive, and it's a matter of luck what you get. The worst ones were the JJ-Gold, they sounds like a gramophone. The PSVANE 12AU7-TII are among the best, super low bass, airy highs, very natural mids. The EH Gold are somewhere in between; Genalex Gold Lion and BTB-4SA Performance are also somewhere in between, but at the top. The SIEMENS have a slightly better kick bass compared to the PSVANE. Then I tested the Northern Electric. Wow!!! Sounds pretty much the same as the SIEMENS!!!! Northern Electric are identical to Sophia Electric, but much cheaper. Northern Electric / Sophia Electric and PSVANE are the only 12AU7 tubes that have a shielding plate between the systems! Whether Northern Electric or PSVANE, that's a matter of taste. The PSVANE sounds a little bit softer, perhaps better suited for vintage music.
