I initially bought 1 from China and after a week bought another 3 - 300 Baht each about $10.
2 attached behind my speakers 4 foot above floor level ,on a sliding glass wall door with double sided tape-curtains always pulled across. The other 2 , behind listening position -again fixed with DST. The generators get quite warm once activated.
Something going on for sure . I am more focused on the music because of the extra clarity ; But , as a negative , I am experiencing some tinnitus , which could be attributed to loud and long playing sessions or the medication I take - Cardiprin
Pet Sounds -Beach Boys classic album from the 60's - I have found the stream -Both Tidal and Qobuz is almost unlistenable , because of DRC. With the SG's on the harshness is reduced to a level where I can at last enjoy this great album.
Eva Cassidy Essentials, it was always very good, but now is spellbinding .
Like other comments on here , my partner -30 years younger than me , has commented, that, "it sounds very good now ".
