Well I've never left the top off with it running, so I can't tell you if the transformers directly get warm. But the case itself never even gets warm, stays cool no matter how long it's on.
If grain is your main concern then you should take a serious look at the Neko, it has zero grain which I'd attribute mostly to the transformer coupled output.
Yeah I heard after the game about Ovechkin, serious injury though I kinda doubt that. There was definitely something wrong with Green he was abysmal in the series.
Anyways go Pens!
Hoping Carolina can win tomorrow and give the Pens home ice.
The Dynahi is about as transparent as they come, IMO it and the B22 are the top of the heap when it comes to solid state amps.
Haven't tried the APL Denon in the headphone rig yet but I might do that when I try the Neko out in the speaker rig.
