Rather than jumping ship, why not stick with AudioNote for the favorable reasons you mentioned in your post. My local 56-year-in-business audio dealer demos all models of the AudioNote speakers and amplifiers, sources, etc. He also offers electrostatic speakers along with lots of trade-in units to compare to. All fun to listen to yes. Better?, hard to say, maybe not.
The all AudioNote matched systems, speakers, amps, sources, are some of the most enjoyable and engaging to listen to every time I go in there. If you are more into musicality and engaging sound, there is more to be realized imo. Jumping ship just to try different technology, while this can be fun - it’s a bunch of different rabbit holes to explore. Geez, it takes a ton of time to get it right, or never get there. A well designed (matched) system can be end-game for many. I see a lot of very nice trade-ins at this dealer, and what their next AN end-game system looks like.
How much have you listened and experimented with AudioNote amplifiers to pair up with your AN speakers? Have you jumped up the line with true AN amps and sources? I’m not referring to the AN-kits. I’m asking about the AN amps made at AudioNote with the most choice parts used. Go to one of the audio shows if you can. Lots of fancy rooms, and often times a simple AudioNote room down at one end somewhere at the show. Sit, listen, and decide for yourself how it sounds for you. Ignore the hype at these shows, and compare to all of the other fancy and overly-technical gadget rooms. What's more "musically engaging" to you?.
Stepping up on the AN amps with your current AN speakers is another chapter or two yet to go - if you’ve not tried this yet. Trying this first, and then jumping up the line in AN speakers might be something else to try before jumping ship to another batch of mixed technologies that may not work as well together. How much do you enjoy exploring new technology -vs- simply buying and listening and enjoying "music" with a well integrated system is what I’m getting at. Best of Luck on your decision.
