I use this amp for 1 month in my studio (with M6).
It has a high accuracy. a very good image. Trunk!. a nice low Medium ...
Very high quality which makes audiophile amp that completely buries my NAD, ROTEL neighbor's etc ...
Namely you should let it all the time turns cold because it has a little shrill treble which disappears after qqs hours. (At least 2). and then ... happiness. In the studio with the M6 is a treat. (At least initially, because of course after we forget)
It allocates only one goes qudn sound loudly.
For the type of use is 3 in 1 HiFi Audiophile, Studio,
Even for small PA teuf friends ... (2 X 150W into 4ohms)
Caution is not limiting, as in other series 9. So it easy ... if not fuse.
I came across it by "chance" to corner of a ebay auction.
new state ... really cheap but not expensive. (I'm not a good example).
But the price of nine PSS. No need to go to crown and others ... well take the PSS "franchouillard" (assembles a beucaire (30))
The amp is guaranteed 10 years.
I would do this choice rather than ten times.
Since then, my neighbor sold his for aquérir ROTEL 1.
