Gmood,
I actually bought the SonicArt on Ebay.They are an obscure Aussie company-
www.sonicartaudio.com/
There is no mention of the 3876T chip amp on their site but you could email them for info.
Just last night I dropped off the 4780 amp at a friends.He has an M.E. 850 transistor amp which are monster things and very highly regarded in Australia,and found in many seriously expensive systems.The chip amp,at least to my ears,sounds vastly better.The soundstage went from being very box bound to having depth,layering and projection and the whole sound was just clearer,faster,more vibrant and more detailed.Like lifting several blankets off the speakers.
