That's 'music to my ears' as I've had extactly that nagging doubt at the back of my mind for years!
I've harboured a nagging regret that I could've had better SQ if I got a stack of Klouts for my activ setup. That name: 'KLOUT' really worked on me as that is exactly what I want from my amps, especailly in the bass aspect.
It's the cost that has stopped me over the years as the Klouts always seem to go for well over a £1K each (LK280 is less than half that). Also I studied the internals with as much detial as I could to see if there is a real design difference to a Klout over an LK280 and to me, I couldn't really find it ( just by looking at online pics). The case was much nicer and the connectors on the back are different, but the actuall transformer and amplifilier boards seem to be almost identical to the LK280. I think the specs were almost identical....but it's that name!
Anyway, thank you sharing your experience, I'll enjoy my setup even more from now on!
