RME ADI-2 DAC FS is it "All That", especially for under $2,000?

I am upgrading my main system with a Mark Levinson No 532H and pair of Tekton MOABs, arriving in the next few weeks. I decided my Music Hall 25.3 DAC should probably be upgraded as well, I have a PS Audio preamp I was planning on still using.

I am getting a lot of recommendations for the RME ADI-2 DAC FS, and some are saying replace my PS Audio preamp with it also. Pretty much every review or even mention of it I can find, comes with descriptions like "End Game product regardless of price" and "State of the art".

I am not an owner of this DAC neither I have tried it but I have read
I’m tempted to try a Sbooster or Pardo PS to hear if this thing can get any better.
That an LPS provides some enhancements, I am following this thread because I have been wanting to get one, very split between the DAC and the FS cause I would like to possibly record vinyl

Just to be clear I’m not saying one has to throw on LPS to get great sound out of the RME as it is an outstanding DAC regardless of the price. What I am implying is I’m curious if an LPS will take it to another level and if so I’d spend the $400. I have an email into Teddy Pardo on his thoughts and if he has or will build a LPS for the RME. If I don’t hear anything back then I’ll explore the Sbooster.
Agreed, most people report excellent results with the stock Dac.I would also look into John Kenny's (Ciunas Audio) super caps LPS, 3A nominal and good cost possibly under $400Anyone here using the ADC to record vinyl? Good results?
I just ordered this DAC.... can't wait !    I'm using a NAD M51 which is a fine DAC so the comparison should be interesting.    

One of the reasons I bought this DAC is to use its crossfeed circuit with my Quicksilver headphone amp.  That along with its feature set.  I rarely buy anything sight unseen or unheard but hopefully it's as great as everyone says it is.

I actually found the ADI-2 FS to be too much on the high frequencies for my liking and ended up keeping the NAD M51. The ADI-2 is definitely more detailed than the M51, but who cares about detail if you can’t actually enjoy listening. Compared to the ADI-2 FS, the M51 is rolled off on the high end. And that’s even with the ADI-2 FS using the NOS filter. I realize the ADI-2 FS has a parametric EQ, but what’s the point in eq’ing the thing to sound rolled off on the high end? With EQ adjustments it lost the edge in detail that it had over the M51.

Just my $0.02. I had high hopes for the ADI-2 FS but it ended up being too ’studio’ sounding for my tastes. I find the M51 to be more musical whereas the RME was more analytical.
