Lab12 Melto 2 - tube rolling


Just acquired a well cared for Melto 2. Wanted to give a tube phono stage a try in my system. 
The unit comes with stock 2 Electro Harmonics 6922 and 2 OTK1 Russian military 6n23p EB tubes. 
I’d like to hear from the Melto 2 owners, or owners of phono stages that utilize 6922 tubes, about your experience with replacing EH 6922 with better tubes.

Sound characteristics - what changed, what was the improvement?

Considering current production Gold Lions as I remember liking them in the Rogue line stage…but those were 12AU7 and not 6922. 

Table/cart - VPI Prime X/Hana Umami Blue

Cables - kimber carbon phono from table to Melto2, kimber carbon XLR from phono stage to integrated

Any thoughts?

Gold Lions are what Conrad Johnson uses these days.  I have been happy with them.  I cannot say that I notice much difference due to break in.  I am not saying it doesn't happen, I just have never been convinced.  Call me a hard sell.  Anyway, when I take out an old set and replace them with new ones, if there were a difference I am not trying to recall what they sounded like 100 hours ago.  No it is an immediate, right now difference.  Do I hear any difference?  No I don't.  If you get the chance, try testing that way and determine what you hear.  YRMV.

@billstevenson they might not change. I’m quiet happy with how they sound. Listened to few albums already. 

I am curious if you have played with the capacitance settings with a MM cartridge.  I am interested in the Melto-2 or the new Luxman E-07 because both facilitate doing that.  

@billstevenson no I haven’t - I only have one cartridge, Hana Umami Blue, and it’s a moving coil type.
