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?

Understood.  I have more cartridges than good sense.  Because I acquired a large estate collection last year and many of the records are not in the greatest shape I have been playing a lot of them with MM cartridges.  I have two TTs set up so it is easy to switch.  The best MM are extraordinary and your Melto-2 would allow optimization if you ever want to experiment.  On an unrelated topic earlier in this tread there was discussion about Dexter Gordon, I am a big fan, but I wanted to mention the latest Tone Poet release of Fred Jackson.  Anyone who likes Dex would probably like Fred.

@billstevenson thank you for the music recommendation. I’ll give that album a listen. 

Sounds like you’re busy going through that vinyl collection :)

As to MM and Melto 2, in the stereophile review they were pretty thrilled with the sound of the 2M Black LBV with this phono stage. So I would assume they were able to dial that Ortofone cartridge in. It’s unlikely that Herb Reichert would listen without optimizing the setup. 

@audphile1 Just came across this thread. Thank you for starting it! Coincidentally I have a Melto 2 + VPI Prime with fatboy gimbal arm and Hana umami blue cartridge. Very similar to you. I haven’t tried tube rolling yet. So far what are your favorites? I listen to jazz also.

The latest Tone Poet, Dexter Calling, showed up yesterday.  Recorded in 1961, Dex was in good shape, Kenny Drew, piano; Paul Chambers, bass; Philly Joe Jones, drums.  Unusual for Tone Poet it is Stereo.  In my youth, I wanted to be a jazz drummer.  When this was made I was studying with George Stone in Boston, later attended Berkley and then went into the Navy Band.  The best day I ever lived, I couldn't turn pages for guys like Philly Joe, and he just kills it on this record.  It is good for me that I was smart enough to go to college and learn something I could do well. 

@pbecker128 nice! 
I was about to post an update on tubes. Long story slim, the Gold Lions are just OK, nothing special after they broke in. I would characterize them as slightly dry and solid state sounding, not much going on as far as tube magic in the mids. They’re quiet and neutral but dry and even slightly dull musically. 
I prefer the standard stock EH. Will probably sell the Lions. 
My favorite are the 1976 Siemens. Fantastic tube. Midrange bloom, clarity, texture and great soundstage. I yanked the GLs out yesterday and put back the Siemens. 
I also tried and liked the NOS Russian 6H23N EB and they’re very good. Better than the GL but slightly reserved up top. 
 

What gain and load settings are you using?
