No need to apologize for loving your gear!

I'd never heard of the amps and always enjoy reading about anything new that's carefully made. Whatever you think about 6moons, you've got to appreciate the concerted effort to show internals and discuss design decisions. At least there's some objective information there to learn from and use to supplement the usual subjective adjectives.
I've been trying out a new pair of Nenuphars for about a week now and I'm mighty impressed

@jollytinker  Congratulations. It's wonderful to hear you are enjoying them paired with your Thoress EHT monos.  Looking forward to hearing more!

Question for Stephen:
IIRC, the Vinnie Rossi integrated has a pre-out. Did you listen to the DHT preamp feeding your SIT amps?

I did listen to the VR L2i SE driving the SIT-1's though its DHT preamp stage with the ELROG 300bs.  It improved the SIT's  soundstage and it's lower mid-range very slightly from the PL XP-32 which I thought was heaven with the SIT-1s. But the L2i-SE straight up beat out the XP-32/SIT-1 combo with more extended and open highs, a more detailed lower mid-range and more powerful and tuneful bass (I took notes.) Overall it sounded more present and dynamic, closer to live music.  It was not a difference you had to A/B to get the gist of.  I was shocked, thinking I was doing my dealer friend a favor by giving the VR a spin with the Nenuphar's.  He was just curious.
I’ve got about 60 hours on the speakers now and I can report that I don’t hear any "lowther shout." The top end was pretty strident at first but it now sounds very natural. The bass at first was MIA but now it’s coming in nicely. I wonder if the youtube videos that seemed to reproduce a ’shouty’ sound were made with newer speakers that weren’t fully broken in?
