Looking for a streaming DAC around 4k

Hi all:

It all started when I decided to upgrade my Bluesound Node 2i to an Eversolo DMP-A6. I loved the sexy touchscreen, internal SSD, etc. of the Eversolo. What I wasn’t prepared for was an immediate and obvious improvement in sound, especially in vocals. Vocals were much easier to understand, more clear. This was even obvious when I hooked it up to my second system, a Marantz HT receiver and a pair of ancient Dynaudio speakers. It was so obvious my wife noticed at once, just walking by.

So I’ve been wondering if upgrading to a better streaming DAC would give me another major improvement. I’m retired so I can’t make any $ystem wide improvements, and my system, by the standards of what I see here, is very modest to begin with. Also, I need my system to fit into a certain cabinet, so I need a one piece DAC/Streamer, I can’t have separates.

Current system:

Integrated Amp: Marantz PS11S1, from their Reference series, about 2007. I like that it has both MM and MC inputs.

CD Player: Marantz SA-15S1, ditto. I like that it will handle SACDs and it has a digital out that I would try and run thru the new DAC.

Current DAC/streamer: Eversolo DMP-A6

Speakers: Dynaudio Focus 220s, the original model.

Turntable: Not really applicable here, but I have a Basis 2000 deck with a Vector 3 arm and an Aria MC cartridge (forgot the exact model).

My budget would be under $5k total, so let’s call it $4k plus sales tax. I have no problem buying used. I would love internal SSD storage. I would also love it I could use my standard .m3u playlists with said internal storage. Love sexy touchscreens even if I mostly use the app on a tablet. Lol. I don’t have Roon and no plans to get it.

What do you think? Thanks!
