Where to take system from here?


Fellow members.  Need some advice on what to do to get the greatest improvement in my system. I have been largely out of this hobby for the past 3 years.  Looking to get back into it and want some recommendations on where to go from here. My room is 19*14 feet with 10 foot ceilings. I like all kinds fo music except heavy metal and rap. My largest preference is for female vocalist, acoustic/electric guitar.    My current system is:

PS AudioDirectStream DAC/Bridge2 - connected to MacMini music server running AmazonHD Audio and JRivers - had 5 years
Thiel 7.2 Speakers - had since 2007 - Had Thiel 6's prior to that
Lamm M1.2 Monoblocks - had 6 years
Kimber Select 3038 Speaker Cables 
Kimber select 1132 Interconnect

My prior system I was running Krell 350MCX monoblocks into a Krell KCT Preamp into my Thiel 7.2s for 10 years.  My system was in my basement which was a very large room (70*28) and handled the Krells into the 7.2s well.  I was using a Sony SCD-1 that was fully modded by Richard Kern, which was a huge upgrade over the standard player.  I wanted more warmth and less bass/slam when I moved to my smaller current room and the Lamm's gave me that.  I considered moving speakers at this time but never got around to it.   I still have the Sony  SCD-1 Player but have not used it in 5 years. I have never connected it to the PS Audio DAC.   Where do I go from here?  What parts of my system would you consider upgrading/what adjustments would you make?  I have considered going to Wilson speakers with the Lamm's, which I believe are a marriage made in heaven. I auditioned multiple B&W's about 5 years ago when I got the Lamm's and did not hear a significant enough upgrade from my Thiels to justify the switch at the time.    Do I keep the Sony SCD-1 or sell it. Will i get any improvement going from the Sony SCD-1 into the PS Audio device. Do I go back to CD's and upgrade my source?   Is digital fully the way to go now, realizing many still have a preference for vinyl.  I do think the PSD Audio DAC is an awesome product.  Given my music preference is it time for tubes?  Appreciate the help.

System looks pretty solid as-is. What do you feel is lacking? I adore your Thiels. Do the Lamms give them enough juice? Have you done anything regarding room treatment?
Start with replacing those metal monsters.I demo'd several Thiels wayyy back,with Mcintosh & A.R.tubes & NEVER heard a pair I could live with...Give me something with an organic sound like Harbeth M40.2 or Sonus Faber...
Thx for the info - The Lamm’s have enough power to drive the thiels - I do notice some  loss at the very lower end compared to the Krell setup but that is ok given room size.  My room was build for soundproofing/diffusion at construction of the house - double walled with sound deadner/diffusion embedded in all the walls and ceiling. I don’t have any other treatments at this time.  Do I dump the Sony scd-1? Anyone compare the 7.2s to some good Wilson’s? I have never heard any sonus Fabre or Harbeth speakers. 
Hi mwthorne: Very nice system you've put together. Myself, I'm looking to buy a dedicated music server. There are many to choose from nowadays.
@mw

What do you mean by "sound deadner/diffusion embedded in all the walls and ceiling". I understand the deadener inside the walls, but not understanding the diffusion. Do you mean inside the walls as well, or something applied to the wall surface?
