Hi to everybody!
I want to know if someone owns this amp, or has a reviews of it. I want to see its internal circuit, to discover if its build quality is of ES level or not. The old xm-gs400 has normal quality , and is a class d snd not from the hires series

I have Focal 165v1 speakers, and I want to add an amplifier. I've tried a Sony XM-7527 amp that was drawdropping, but died a week ago. Now I have to buy a new amp,and I don't know which one to choose(the price is the same):
Sony XM-7547, used(it has an excellent sound but is 18yo)
Sony xm-gs4, new (from the hi-res audio series, the new ES I think. I've found just one review, and appears to be really really good)
Focal fps 2160, used (excellent sound, has few years)
Which one is better?Somebody owns the gs4?Thanks
