Preamp upgrade

I’m a fan of ARC as well. Pairs well with your Treo for sure. I own a pair. You might ask the same question on the Vandy owners forum. Are you running some isolation under your LS ? i strongly advise HRS Nimbus at a minimum…. 

Best to you in your search

It wasn't on your list, but you might consider a Linear Tube Audio MicroZOTL preamp.  I upgraded from two different conrad-johnson preamps.  I was worried that I would miss some of the warmth that the older c-j preamps are known for, but I didn't. I'm using mine with a Coda solid state amp. 

Tubes make a big difference in the LTA preamp.  Telefunken and Siemens work best for me.  

You're already in some pretty thin air, and it looks like your streamer is the next thing I'd consider upgrading. Judging from the sales on the Node I'm seeing all over, there's a new model in the Wings. So you might want to wait and see, or jump.to an Arender or something such. Much more likely to get a bump in SQ there, rather than by swapping preamps.

Consider a McIntosh C22 MK V, synergy with your phono preamp plus the benefits of high resale value and a solid level of customer service.
