Hi.Browsing over the specs sheet you linked, you can boost up O/P power of the module to 200W/C & 350W/C by raising B+/B- to +/-65V & to +/-80V respectively. This will need a 500VA & 875VA power iron, EI or pancake type regardless.
But who needs such high power for home audio?
Dynamic headroom is not decided by O/P power alone. Too high power, too high damping factor delivered to speaker systems of high efficiecny only 'freeze' up the speakers. It can make things worse.
I play classical music, LP, CD & DVD-audio 95% to the time & my power amp is only 35W+35W & "dynamic headroom" is never a problem to me.
Why? Speaker impedance & efficienct matching & the driver pre-amp
never overdrive the power amp.Headroom is the max. power O/P delivered by the amps before clipping. Gain should be just enough to give the enough power & sound pressure levels SPLs to your ears so that there will be amble of headroom reserved for dynamic climaxes.
Before you go further, tell me what pream you are driving the modules & what setting of the volume control you get for your
SPL you are happy with.Higher the volume setting, say beyond 12:00 hrs, better will be the dynamic headroom available & more enjoyable will be the music.
This is my sonic experiences, shared with many other audiophiles.
