Thanks for the great reply ! Unfortunately I have no chance to test the both systems, let alone testing one. I am not super knowledable about hi-fi system but being a musician have it's perks.
1- I'll benefit from nearly all aspects of the M39: FM radio, CD player and of course the built in DAC by supplying the system both with USB drives & digital input. But for now it seems I'll mainly be using AUX and USB MP3 function.
2- I maily listen studio music and those genres: jazz, blues, modern jazz, progressive rock, instrumental and some metal.
3- My main problem is: I don't know if there is a huge difference between Dali's and Denon stock speakers. Most probably I'll be upgrading those in the future anyways.
P.S: Also a friend of mine recommended me audioengine a5+. Reviews sounds cool. Any ideas?
