Finally I bought Audience aR6-TSS today! Originally I've other targets like Equitech 3RQE and Torus RM-16, all these three products are very good, but my home are very small, not much space for Equitech and Torus. Also I need to consider the weight, these transformers are so heavy to move from one place to another place. AR6-TSS is very small , easy to put it anywhere in my home. I'm using a Japanese isolation transformer CSE TX-1200 before I got this Audience product, the sound of AR6-TSS are very much difference with isolation transformer, the mid and bass are not as heavy as my isolation transformer, but still very rich. Also it sound extremely transparency, clean, details and more musical than Equitech and Torus (Only my personal feeling). Now I plug all my stereo equipments in it like CDP, Master Clock, Pre-amp, a pair of Mono-block power-amp and a media player. I'm still experience it, see how much difference after I use it in 400 hours later.
PS: Just want to ask is it very big difference in sound quality after full break in this product?
