We have just received the feedback below from Greg K from Germany! Greg owns a ‘Feliks Euforia headphone amplifier’ which came with Psvane CV181-TII as driver tubes.

Read about his first impression after swapping to [Linlai™ Global] E-6SN7 for 26hrs – it might help those who wish to know how the E-6SN7 compared to Psvane tubes: (note: Linlai tubes full burn-in will take approximately 100hrs)

“I have now burned in the tubes for a good 26 hours so far.And on the Feliks Euforia, where the Psvane CV181-TII were before, a lot has happened. I listened with the Audeze Lcd 2 C headphones which are quite neutral. And relabelled 6080 Sylvania power tubes which also arrived on Saturday.

Compared to the Linlai Global E-6SN7, the Psvane are quite neutral in sound. I noticed this immediately after the exchange. This is no longer the case with the Lin Lai, they play much warmer.

The bass has increased considerably where before they were bloodless in direct comparison to the Psvane CV181-TII. The good thing about the Linlai is that the mids and highs are relatively unchanged compared to the Psvane CV181-TII. I didn’t notice any loss there, they seem to have gained a bit of sparkle.

They are also more accurate, closer to the music and go a bit deeper in the highs and a bit longer in the low end. Detail resolution is also very good, I like it better than the Psvane tubes.

Vocals are a bit more distant and more central than with the Psvane, or less voice accentuated, which I personally find better.

All in all, they are definitely worth the money and improve the sound of the Feliks Euforia dramatically. Before I was always getting disturbed by something, but that has gone since the first hour since the Linlai have been in. I don’t regret buying them. Much more the Psvane that you can book at Feliks.

It makes the Feliks neutral but cold, with the Linlai it’s just the opposite.

That was my first impression and I know they still need a little time to burn in. But they are getting better by the hour. Linlai has done a really good job. It also shows that after such a short time they are already so open and show the direction they are going in.

I am enthusiastic about the tubes. And I wanted to tell you that much about how good they are in the first hour.

With Kind regards
Greg”
