Jbl Project Array 1400 vs dynaudio c1 speakers

C1 are great speakers.  My suggestion is to change the Mc 601 out to a Plinius, better dynamics/transients.   Not to say Mac gears are not great;  your mc601 and Dynaudio is not a good match.  You definitely need more dynamic headroom & lots of damping factor for All Dynaudio Speakers. 

JBL Array has much more realistic and pleasent sound , and dynamic is step above Dynaudio .
No contest JBL is so much better

Draw your own conclusions from some reasonably objective measurements?

I wouldn't consider the jbl array an upgrade in the midrange and highs department, I think a better option would be to keep the c1 and add a pair of subs for more attack and scale.

IMO..as stated above..the new signature C1..

I used to own the Dynaudio C1, wonderful speaker. I also heard the 1400, I think you would be moving a step down. I did not care for the 1400 and the dealer who had it sent them back. Now, in the right room and with the right taste they may be very nice, the horn was very colored and seemed to come out and slap you in the face. You have a really nice system. If you are looking to "upgrade" maybe the new signature C1, I am also wondering what a pair of YG Carmel's would sound like in your room. Your room might be a little small for the C2. I love my verity parsifal's but would worry about being a big boomy in your room. A trial of the new Magico Q1 would also be very interesting. In order to really upgrade I think these are some realistic directions. but that's my ears opinion based on my days with the C1.
