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?

The Gold Lions are in. System was off. Tubes are new. Immediate and initial impressions - very resolving, detailed sound, midrange is super clear without glare, tons of air and very precise. Very nice quiet background and excellent soundstage. 
Now break in begins. Let’s see how they settle with about 100hrs on. 

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.
