funny I was told by a tech that the 1.0t and 4.0t are very similiar and use the same output transistors and the same number of them!!
voltage squared divided by ohms=watts

just needed to add that their mono bridged rating is the same but the 1.ot is rated at 200rms continuous 400 peak i.e 3db headroom at 8 ohms.

The M4.0t has the best top end of any Carver gear I have owned. Sweet roll off, very natural reproduction and smooth mids. The lower end of the frequency spectrum is ample, but lacking in terms of "slam". Not a omission of bass, but not a heavy hitter when it comes to bass output. It is very tube-like sound. Compared to a M1.0t, the differences are quite different, regardless of similarities of components and design.
In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.

They use the same output transistors, yes, but that's probably more a result of the high tier rail voltages being similar than anything else. The rest of the topology is similar on the macro scale, it's a push-pull input, a bootstrap current source, a three tier ladder type class G.

Differences are in the feedback (t-mod) circuit, the bootstrap current source of the M-4.0 is more stout, the drivers are paralleled just before the high tier output.

Not ever having heard an M-4.0t, it looks like it could source a bit more current than the M-1.0t, which may result in tighter bass control...the freq response curve also has a slight rise near 10Khz.
