Eric D. from France is an industry pro specialized in ultra high end cabling. His audition skills are professional and field proven, and here is what he said about after owning a pair of [Linlai™ Global] E-845 top grade tubes:

“The Linlai E-845s are very nicely built. You can tell by looking inside
the glass tube that they are manufactured with care. When brand new,
they performed nicely, but it was after about 120 to 150 hours that they
really came alive. They really need that burn-in time to reveal their
full potential. I’m not the patient type, but this time I was glad I
waited.

All the qualities the best 845s are renowned for are there. Let’s talk about dynamics first : a bit timid during the burn-in time, dynamics become quite exceptional after 100hrs and when tubes and amp reach their optimal operating temperature. They are extremely fast, with lots of impact and speed, speed and more speed. Extension in the bass is quite impressive and treble is exactly what you expect : not a trace of harshness but lots of details. Midrange is just exceptional, voices come alive to a point that I’ve very rarely experienced before. The timbres of acoustic instrument are very real, and that is quite obvious on violin or cello.

Soundstaging is outstanding, both in depth, width and accuracy. And there’s air between the instruments, something you can only hear when you are in the presence of real high-end gear. Pitch-black silence is another telltale sign of that.

On rock or blues, you can easily identify what guitar or amp is being played. A Strat sounds like a Strat, and there’s no mistaking a Les Paul or a Tele for anything else.

Comparing them to a pair of RCAs a friend brought around, the Linlai E-845s did at least as good as them in all fields, but they have a greater sense of immediacy, something that makes you feel more connected to the music….

Thanks a lot Rachel, those tubes are real keepers!

Cheers,

Eric”
