How close dynaudio s1.4 to c1

A friend of mine has the 1.4S and I had the opportunity of listening to it a lot of times, even on my own set up, and I can assure that in general the 1.3 SE is better.
As the C1, the Special Twenty Five is in another league too...it was the one I chose to replace my 1.3SE, however, once more I emphasize that the 1.4S is an amazing speaker...no doubt about that.

Extravaganza : thanks for the info! I like the sound but not the style is to boxy looking:)
hba:thank u for comparison, spesial 25 is good but no luck,
found the C1 but overpriced:(
still waiting

Having owned 3 different Dynaudios including their studio monitor BM6 and listening to almost all their speakers in different demo rooms (excluding the Master and Consequence), it was clear that 1.3SE was their best monitor this side of C1. It was better than 1.4 and some people think it is more musical than Special 25 (I have not heard S25). BTW, my last Dynaudio was a 1.3SE which I used for about 2 years. When I was upgrading, I looked at C1, no doubt it was more transparent and a more exotic sounding speaker. The Esotar2 tweeter is the best I have ever heard, better than any Scanspeak revealetor or ring-radiators. But I still thought the 1.3SE had a more neutral tone. The C1 had more of the "Dynaudio" house sound which to my taste was too much of a signature. Having said all that please do not compare the 1.4 to the C1, they are at different levels especially when you feed the C1 with quality electronics.

Enjoying the discussion, also looking at some C1’s.  Can anyone summarize power source choices and/or ohm - impedance choice?

I’m listening to jazz, piano, acoustic, vocal music these days. The room is 20 X 25’ open architecture fairly lively. Seating for dedicated listening will be available for 1-5 people of course. Simple TIDAL streaming via Sonos and CD.

time flies with music faster,passed 9years:)well the real contender to c1 is  discontinued  s1.4LE. It has new capacitors from mundorf.May be it is the reason why separation between  instruments in soundstage is very good in acoustic music
