Dynaudio C1 vs current speaker-Wilson Benesch ARC

Given you like what you are getting for the most part via the current speakers... and If you seek to lessen the 'fatigue' factor, I'd recommend a couple or at least one power cord change, and or, one pair of interconnects, rather than exchanging your speakers.

I prefer to tweak, massage, or reconfigure and address what's on hand over replacing good stuff with other good stuff and ignoring perhaps some existing issues that won't be addressed by so doing.

Things might be as simple as addressing reflections with some corner treatments or panels at point of first reflection.

MIT gets significantly better in terms of the quality of the signal as you move up... there are however not terribly forgiving.

Maybe something that comes across easier on the source.. or preamp. Voodoo Black Dragon? It'll actually work on anything! Not a lot of money either. An Elrod Sig III on the big ol' CJ SS would help as well, if ya want to buy accordingly to the component.

BTW.. got a power cond in the mix there? that's a thought too. Might just be the power itself.

I've heard the preamp, and got the impression from talking to and reading about the CJ SS that it's mighty revealing as well and can be too articulate up top for some or just hard in the wrong setup. Some nice RCA tubes in the pre could be the deal. I use a mix of them and bugle Boys in my pre.

you've nice gear there.. just look at the peripherals, and accessories before getting rid of anything.
