This thing is a beast indeed, it looks small, but it's very heavy and keeps my speakers under rock-solid control! It is different from the Dussun, other parts where used... ( I dug deep into the dungeons of google to find info) I listened to the dussun , It's good but a bit clinical sounding, this one is very neutral but not clinical at all ( with my speakers) ... Ofcourse, my speakers are on the warm side of neutral , that could explain it.
G&W is getting more and more famous in china, Dussun is not selling very well because people don't like the sound signature ( as described by several sources: very powerfull but a bit clinical and uninvolving) Some people do like this however.... (I don''t want to offend anyone with the above)
Very happy with this thing, I can hear my speakers limitations now, that's to bad
as for Jolida, I heard great things about them, but they are a bit expensive when you get it directly from china ( but some nice Second hand deals )
And Jolida is cheaper in america to.
