Not sure if you'll see this but hope you do. I've been on my audiophile journey and seem to always run into your posts...actually on stuff you've posted in the past on YouTube!  I'm not sure if it's because we have similar tastes in equipment or we're both in Seattle but there's a weird kinship for lack of a better term.  Through some threads you were on, I ended up getting the LM 508ia too with a PS Audio DSD Jr.  Love it!  I'm looking for a SS integrated amp now to round out the LM.  By coincidence I was looking at the Hegel H390, Luxman 509x, Luxman 590axii, and Diablo 300.  I think you ended up buying the Diablo 300?  How do you like it?  Is it enjoyable but different enough from the LM to support having both?  

Nice system @freesole. Nicely put system, especially the Spendor and tube combination. Is the amp able to drive the Spendors properly?

Also, did the Gaia make any noticeable difference on the Spendors? Would love to see a pic of the Spendor+Gaia. How far apart are the loudspeakers? That audio stand gives your system a modern-retro look! Goes very well with the loudspeaker finish.
