Rogue RP-7 vs. New RP-9 - What's the Difference?

I just got an RP-7 recently and I went to their site to look up the manual as I was setting it up and I see they now have an upgraded RP-9 model with different tubes (Russian 6H30P vs 12AU7 in the 7).  I can't seem to make out any other differences.

I thought this might warrant a discussion from those who know more than I do. Thoughts?

I have and love the RP-5. I always thought the RP-7 was a balanced version of the RP-5 without the phono. I'm sure there was more to it than that. I'll be curious how the RP-9 compares to the RP-7 AND Rp-5.

Talked to Mark the owner of Rogue Audio. He said the RP-9 is build for the Russian 6H30P tubes with some different, more expensive parts. He did not quantify the improvement over RP-7. You could upgrade RP-7 to RP-9 for about $3K (with a different circuit board etc.). The real questions for me are (1) how much improvement over RP-7 and (2) how it compares with other pre-amps of similar prices (say $7K-10K). In my experience, may not be worthwhile to upgrade (e.g., I upgraded Schiit Yggy DAC to Analog 2 - but sold it at a loss when I compared the upgraded DAC to Metrum Adagio - the latter is much better).
