for what it is worth, i will share my experiences with a bricasti m3 and m1, along with my weiss 501
couple years back i first tried a m3 and found it to be a very nice, clear and smooth sounding unit... at the same time an m1se popped up and i snapped that up too, so as to be able compare side by side .. m1se was a clear notch better to my ear, better separation of instruments/depth, better bass slam/solidity and better defined image outlines... thus sold the m3, that wasn’t hard
then a few months later i got the weiss, and it took me quite a good while to determine a preference between the two... finally decided that using my favorite filter (amongst an absolutely bewildering array of them available) on the m1, sound wise they were identical to my ear -- i could not confidently hear a difference... both are outstandingly smooth silky yet utterly resolving, with excellent imaging height width depth, and very very black/quiet, yet highly dynamic when called for... but for me the weiss then clearly won out on ergonomics, features (sophisticated dsp, simple yet effective room bass correction, small form factor, hp socket, better streaming) ,,, the bricasti also had its rather cumbersome stone-age ir pigtail remote setup ... so i kept the weiss (to this day still have it, upgraded to 4ch thereafter) and off went the bricasti
both outfits are stellar, highly responsive to queries and just class acts all around
hope this helps
