I can afford to leave mine on 24/7 because it is very high efficiency. I have owned all tube systems, and class A & A/B amps. For me the inefficiency of A/AB electrical
idle
costs are their Achilles Heel, and so I have l searched for comparable sound from class D amps.
I have owned 5 different mfgs class D offerings. Overtime, they have improved significantly. Case in point (fast forward to today) Ric Schultz's EVS 1200 is dual mono, using the latest IcePower 1200AS2 modules, pumping out 600wpc in 8 ohms, which he then mods. Unlike 4 of the other well known amps, this one has taken my Emerald Physics KCIIs to a much higher level, no longer needing my 2 SVS 12" subs to get solid, tight and tuneful bass
It's a bargain at ~ $2300 and has a 30 day money back
