Hello everyone, My SAM has been with me for 4 years now.
Things has been good and bad.
-Drive with proper power amp (FW F5 in my case) will give SAM more authority, in a bit sacrifice of transparency, without enough powercord and interconnect it is hardly notice
-Power conditioner (UPS online, iso transformer in my case) will benefit for speaker transparent as SAM. Not all UPS online is the same, pick one without remove the third, fifth... order harmonic.
-Better source ( mini PC with Linear power, OCXO USB card, DDC, proper fiber isolation, good OS and playback software) will also benefit SAM, more transparency, reduce digital glare, and surprisingly , bass respond.
-Room treatment help a lot (ASC, some diffuser,..) in term of bass eveness, and soundstage. quite critical in my small room, but I do it last.
Btw, one pair of speaker won't forever, if anyone know any speaker that can outshine SAM in every aspect, please let me know, I know it will be a different price range , more than 2k.
to share my experience, I've test with Scansonic Mb1.b, Dynaudio bs, Gracioso 1.0..... Only Gracioso 1.0 can beat SAM, but not in imaging, and it a 5k speakers.
