Upgrade PS Audio DSD Mk1 to?

I've got a bit of upgradeitis.  My current DAC is a PS Audio DSD Mk1 that has had the xfrmrs upgraded and Vcom mod done.  I like it and the music it makes but I've got an itch to upgrade.  My first, and obvious, thought was a DSD Mk2.  I've also been thinking of the LTA Aero and Lampizator Baltic.

What am I looking to improve?  I find the Mk1 a bit noisy and rather long in the tooth.  What do I like about it?  It doesn't sound "digital" and i find that it's pretty even over the frequency range and the.musoc has good flow.  I don't like hyper analytical, dry music that can cause listener fatigue.

Budget is $5k or under and I dont mind buying used.  My main concern is that the dacs listed above will be a slight lateral move and not a real upgrade.

I think my virtual system is up for reference.  If you can't find it please let me know so I can fix that.

Has anyone compared the DACs I'm interested in or have first hand experience with them?

Thanks in advance
