New DAC or New Speakers?


I’m planning to blow some money on my system and can’t decide if I should upgrade my DAC or my speakers. I’m going all in on one or the other, not both. 

I have ethernet and fiber optic switches feeding a Lumin U2 mini modded with an external power supply. Two USB reclockers going into an LTA Aero DAC. Running a VAC Sigma 170 tube amp to Harbeth SHL 5+ XD speakers with a sub. 

Everything sounds great, and I recommend all said equipment, but I have a chance to make an upgrade. I’m considering swapping the Harbeths for some Devore O96s or swapping the Aero for either a Totaldac, or maybe a used Aries Cerat Helene. 

I can’t decide which route to take....

Oh lots of AB testing. One DDC (LHY UIP) adds warmth and density, the 2nd (Gieseler Reinigen) expanded the soundstage by a huge amount, all while keeping the benefits of the first DDC. 
System sounds excellent and I find no faults. I just have an opportunity to improve it further and am treating myself. 
I’m probably going to demo some floorstanders, Acora MRC 3, but the wife I know ain’t gonna like those. Much safer with the Devores. Thanks 
 

Interesting.  This is first time I have ever seen people doing that.  Money wise, it is on par, if not over, with Denafrips Gaia.  Wonder how that stacks up with your combo.  Very interesting.

@lanx0003 From lots of head-fi discussions based around the LHY UIP, my 2 DDC's supposedly sit above the Gaia and up there with the Phoenix. Can’t know for sure without testing but I believe it. Lots of Head-fi peeps are running DDCs in serial.
