LinLai WE 300B or the LinLai Global Elite Permaloy 300B tubes ?

The 5 year warranty for the WE-300b is crazy. Not even the Japanese offer anything close. 

Tinear123...  Can you tell me a little more about the sonic differences you're hearing  between the LinLai E-series 300B and their WE 300B ?  
How long of a break-in of each before they stabilized ?  

@david_ten

Just to make things clear my WA5-LE is a fully upgraded (standard attenuator, not Alps, etc) Mk 1. Whether the upgraded version was worth the money (~$1K), I honestly don't know as this is the only one I've heard! But I do enjoy it and find it suits my tastes.

My recent dealings (last year) with Woo Audio, were not great. I had an issue with the anodising on part of the power supply unit changing from black, to a burnished brown. Woo basically said tough luck, that's what happens, especially if you have any sunlight on your equipment!!! My gear is kept in a rack well away from direct light.

I found the person I was dealing with a little obnoxious, in that he was more interested in upselling (a new WA amp and more expensive tubes) rather than dealing with what I wanted fixed.

Electrically/electronically the amp has been reliable, with no issues to date.

Though I'd owned tube amps before, I'm surprised at just how much I've spent over the last few years on tubes for this beast. It's at least 3 time the cost of the amp!

The headphones I used with it are:
Senheisser:    HD600, HD650, HD800S
Focal:             Elear
Audeze:          LCD-X
Meze:             Empyrean with their silver cable

My outright favorites are the Meze Empyrean's and yes the silver cable upgrade is worthwhile.

All the best from NZ - Peter

@peterh_nz  Peter, thanks for the detailed response and the information you shared. Very helpful. 

I have Focal Utopias and the HiFiMan HE1000 and HE560. HeadAmp GSX-Mk2 for amplification. DanaCable leashes.

@liquidsound  Will you be bringing in the WE-300B for comparison purposes?
