If he wants less heat, how is he moving to pass?
And the evo ones are one of krells best... I'm not sure just any pass will do, it would have to be the xs series.
My rec would be something like the momentum?[/QUOTE]
The 600.8 Class AB monoblock's only works in Class A the first 50 watts.I know this model and know the Evo One's, i assure you that with the 600.8 you have less heat and a terrific sound too.
Read this review in comparison with an XS 300 and tell me after...
