Dynaudio 1.3mkII Vs Proac 1SC

I don't want to confuse you, but I have owned both, I now own a pair of Tyler's ref monitor which I like much better, the drivers in the Tyler's are better in detail and have the best vocals, of the 2 you mentioned I would lean towards the proac, good luck to you

Don't forget about effeciency and matching. ProAc will be much easier to drive and would work well with SE tubes. Dyaaudio is rather tough to drive and generally sound better with solid state. Good luck

For $550 look into the Magnepan MMG, if you have enough power (above 25 excellent watts). Needs some room to breathe but nothing stand mounted can touch it in my opinion. You can really 'see into' the recording with this speaker. Imposing physically, about 48 inches high, 16 inches wide, but only two inches thick.

I agree with Flying, what amp are you going to use? beefy SS will be better of with the Dynaudio and the ProAC sounds awesome on tube gears.
