Improve sound

I have a pair of martin logan 40i. Blusound node most recent version. Anthem mrx 720. I have the speakers connected with bi wire blue jeans speaker cable. The blu sound via optical cable.  I have about 1000 dollars.  What could I upgrade.  Thought about getting an amp like the parasound 23+ or upgrading the streamer to a cambridge. Please I would love some help/suggestions.

With ESL's the typical weak links are the amplifier and the room.  The ARC should help improve the amplifier performance though.  That leaves the room.

Those aren't ESL's it's their box speaker with the AMT tweeter.

I like the Martin Logans. I think a tube DAC might give them real warm and liquid sound. MHDT Orchid comes to mind.

Although your speakers have a fairly high sensitivity specification, they are a 4 ohm impedance load. Your amp does not provide a spec into a 4 ohm load. My guess is an amp is needed that likes a 4 ohm load or find a speaker with 8 ohm impedance.
