Hi! I am a new member of the forum looking for advice. I am considering a pair of Definitive Technology StudioMonitor 45 to upgrade my old Polk Audio R15s. Main use is for listening to music (mostly jazz, but also blues and rock, and sometimes classical) in my office, which is about 11' by 11'.

Another choice would be the Audioengine A2+. These are smaller, include amplification and DAC. But according to what I have been able to find in the web the DF SM 45 seems to be a better speaker.

Thanks!

Manuel
