Oh I know larger monitors have better stereo imaging than the M50s. Once of the draw backs of having the sub fill in the mids.
I just did not have space for larger ones and the bass is better then 2.0s like MkII.
He ran the spitter from the dac so when he used the DACs volume control both the speakers and the sub would increase in volume.
For 300.00 I could not find anything better that had decent bass.
The trouble with the other 2.1s I tested is they had no midrange, big hole in the music. The swans fill that gap better but do sacrifice some imaging due to the sub producing some of the directional sounds.
Also I like having 1 on/off volume control vs reaching to the speakers to change the volume. Did not want to get an external DAC for that as I already have a decent enough internal one, and I borrowed a usb external and the sound was about the same, so that saved me 150.00.
Speakers are all subjective anyway. Some people love boomy bass, compressed sound etc.
The swans just sound full with much better midrange than the other 2.1s. Most of them did not have enough midrange and the subs were sort of a 1 note boomy sub.
They not going to be as good as larger monitors but again for the size/space/price not much out there better. if there is one name it.
