Ratings & Reviews
Rogue Atlas Magnum tube rolling
I'm tube rolling different tubes in my Rogue Atlas Magnum. I'll keep this short: this is my favorite tube in the 12AU7 position. It is musical!
The other 12AU7 I like is the JJ 12AU7 Gold = cleaner with voices but not as musical.
Sounds great with my headphone amp
I recently purchased a Bravo Audio Ocean headphone amp, which came with a Shu Guang 12AU7 tube. It sounded fine, but I was shocked at how much the EH Gold 12AU7 tube improved the sound coming out of the amp. Before it was a bit muddy, but now it has a clear, warm tone.
Wow! What a difference this tube makes.
Purchased this tube for the Bravo Ocean amp. It is a great match for this little amp which I use with Sony MDR-V6 headphones. I listen to predominately, classical music. I purchased the Genalex - Gold Lion ECC82 a few years ago which was a big improvement over the originally installed tube. However, the Electro-Harmonix is a great match with this amp. Silky smooth strings, piano tones have the higher harmonics and overall the sound is richer than with the the Genalex. Thanks to the previous reviewer for posting their review which led to this purchase. Great investment!
Good price for a nice tube.
Just put these into my Copland CTA 301 and wow they're fantastic. I could not be happier. Perhaps there are better tubes out there but these guys sound great
