Gainclone vs. Pure Class-A

I made a gainclone with premier parts such as blackgate caps 2 years ago, it sounds very good. However I still prefer class A Aleph, warmer, sweeter, more liquid, less ss taste.

I have a pair of 200w Rawsonte monoblocks which replaced a pair of class A Monarchy SM-70 monoblocks (70w). Driving a pair of very inefficient NSM minimonitors (82db), I much prefer the Rawson amp, for both dynamics and imaging.

Perhaps a slightly skewed example, but I own both a gainclone and class-A amp built by Tim Rawson. The gainclone being a dual-mono 200watt, the class-A a 15watt Aleph clone.
Which I prefer depends on my mood and music being played.

Strengths of the gainclone; Smooth mids and highs with "Reach out and touch it" transparency, stunning soundstaging front to back/side to side with pinpoint imaging.

Strengths of the Aleph; Perfect tonal balance top to bottom, more weighty presentation overall lends to more natural sounding vocals, strong articulate bass.

Both remarkable amplifiers, neither of which I'd easily part with.

I'm thinking about a moving to Gainclone amps from pure class A or class AB. Do gainclone amps consume a lot less electricity than Class A or AB amps? Some of my Class A and Class AB amps draw 200-300 watts at idle and require quite a bit of warm-up time as well. I'm hoping to move onto good sounding amps that won't draw so much. I don't mind waiting for the amps to warm up. It is the draw that is getting me now. I'm jsut trying to trim the electric bill.

Thanks in advance.
