Linlai E 6sn7 tubes

When I rolled, all the combo's where w/Linlai's. I just found that the bottom end was a not a clear as my other tube combo. I did notice that they made a stronger impression in the volume. They just don't do it for me, but neither does McIntosh, which I find warm.

The tubes from Viva also had the ringed base as the ones from Grant Fidelity. The lettering was different & the sound from the Viva’s were not as refined (open) & were base shy.

Hi @danmar123, my point was that the ones you bought from Grant Fidelity has the ringed base, but the one that is pictured on the Grand Fidelity doesn't.   The fact the base of the tubes you got from GF look identical to the ones sold by Viva might suggest that they are both manufactured by Linlai but with different letterings.  But as I mentioned earlier, Linlai would not acknowledge the ones with the horizontal letterings.

It's good to know that you do hear differences between the ones from Viva and Grand Fidelity.  I wonder if the ones sold by Viva and other Chinese retailers are rejects that didn't meet the tight QC requirement, and hence sold at a lower price.  Just another guess.  The mystery continues...

Thanks, @danmar123, I appreciate your response!

It would be interesting to hear any other feedback on the Linlai Global Es - especially comparisons with other tubes - and perhaps including thoughts on the bass region.

The tubes that’s are being sold at Grant Fidelity are very high quality.
