Calling all Marantz Ruby owners
I realize this was posted quite some time ago, but I’ll provide my answer anyway. I use my Ruby pair with Spendor A7 speakers. I think they sound great.   
Audition Spendor D7 and A7 in/near Texas (Houston)
I’ve not hear D7’s but I purchased a pair of new in-the-box A7’s for $3200. I’m very happy with them.  
Best Bookshelf speaker 1300.00 budget
Also suggest used. With a little research and watching audiogon, you can get 2 to 3 times the speaker for the same price. A year ago, I bought a pair of $4000 speakers for $1800. They are as new in all respects - and I'm really glad for the extra ...

TSM MMii..........amp pairing??
I have the TSM MXe speakers. I'm using a Rogue Audio Cronus Magnum and am quite satisfied. I typically play CDs and use a Rega Apollo. Also a Sonos for Apple Lossless. 
Speaker for Rogue Cronus Magnum with high WAF
I have a Cronus Magnum and Merlin TSM MXe speakers. New, these speakers cost about $4k (current Is MXr) but they can be found used in the $1500 to $1800 range. I put mine on Sound Anchor stands and they sound just great with the Magnum.

Has a lot to do with attention to detail and overall user experience, though. 
solid state amp for merlin tsm's ?
I've tried my TSM-MXe's with a Luxman L80-V and Adcom GFA5400 / Adcom GTP-450 and they sounded very good in both cases. The integrated I am using now, and prefer, is the Rogue Cronos Magnum, which is a tube amp. 
Amp suggestion for Merlins?
Just to wrap up my own question - for several reasons, I ended up purchasing a Rogue Cronus Magnum. No complaints. First tube amp. We'll see what the future holds. Thanks to everyone for their excellent input. 
Rogue Cronus Magnum preamp tube
Btw, I must say the Cronus Magnum is quite excellent. 
Rogue Cronus Magnum preamp tube
I'm also not keen on the stock preamp tube. Currently I'm trying a JJ (Tesla) 12au7. I've read good reviews on Psvane so may try that as well. I do think I'll check with Rogue first.
