Genalex - Gold Lion ECC82 / B749 | Not as good as expected

by -

After reading some good reviews I gave the GL-ECC82 a try and used them in a BHK signature preamp and the VPI 299D integrated. A tonal pleasing presentation however the sound stage deep and width suffered as well as details in the upper region and bass. In comparison the Electro-Harmonix Gold tube does a phenomenal job throughout the entire spectrum with a more neutral tonal presentation, but still engaging. A must try tube for the asking price.

Genalex - Gold Lion ECC82 / B749 | Vocal clarity


Have been wondering about rolling tubes in my PrimaLuna EVO 400 integrated. Figured I would just buy two GL-ECC82 for the gain section, if it was no big deal I can stop spending. Switched out two stock tubes and put on new Chili Peppers record, didn't have to read a single lyric, every word is so clear. Not a small improvement! They only have a few hours of break-in. Driver tubes next lol.

Genalex - Gold Lion ECC82 / B749 | Very Impressed w/ the Sound!

by -

I bought these GL-ECC82 for an xDuoo TA-20 headphone amplifier and these tubes have made it hands down my favorite amp out of multiples, including my beloved THX 789!!

Musical, lots of bass, amazingly subtle distortion that takes the sharp edge out of a lot of harsher albums I'm trying to get into (mostly speed/black/symphonic metal stuff) and makes mellower albums sound so wonderfully retro in the best way possible.

I'm here on this site right now to buy some backup Lions just in case....

Genalex - Gold Lion ECC82 / B749 | Decent current production tube


Compared those GL-ECC82 with various NOS tubes (Philips, Mullard, Brimar) and current production TUNG-SOL 6189 in my phonostage. In my setup these sounded bright and with quite light bass. Soundstage is big and it provides a lot of details, which does not compensate however the lack of sound balance. I also have the GL ECC83 which have similar sound signature. From current production tubes preferred the TUNG_SOLs which provide better bass extension and seem to be more colorful overall.

Genalex - Gold Lion ECC82 / B749 | Unexpected sonic improvement

by -

The tubes arrived today and so being curious I installed them into my Prima Luna Dialogue Premium Integrated. I’ve never upgraded signal tubes before; was not expecting a lot of sonic difference. I’m pretty surprised now after 4 hours how much music I was missing before. Don’t get me wrong, the stock PL tubes get the job done. These GL-ECC82 are quite a bit more forward, resolved and have great stereo imaging. So far so good. I was on the fence to spend hideous money on Cifte, but talking to thetubestore helped me out. Overall a much needed upgrade. Very happy!
