All have SMPS (switch mode power supply), but that does not make it a class d amplifier. Aguilar's 500 series use a class d power section (or as tripath called it class t) |

To the OP, and in the spirit of your request, the LMII/III, LMTube, and all the other 500 watt models are not class D amps, they are traditional class A/B amps. They do use SMPS, which is why they are so light.
Class of power amp is becoming pretty much a zero issue. Listen to a TecAmp Puma500, a Markbass F1, a GL MB500, a Genz Shuttle 6, and a Markbass SD800 and then describe to me what a 'class D' tone is, or what a class D amp sounds like. There is no class D sound, just another way to get generate relatively transparent power so that the voicing of the pre comes through (albeit in a more efficient, small and hence lightweight format).
What the OP is more likely asking is for a list of SMPS amps, which are, by definition, small and lightweight, regardless to the type of power amp used.

And this can go for class-D, too. While both switch-mode power supplies and class-D topography do allow for smaller, lighter amps (and this is where they are most frequently used), I would not say that SMPS amps are by definition small and light. For instance, the Ampeg SVT-8Pro, while not overly cumbersome, is a "full-size" 2U head, weighing in at 23 lbs. That's not bad for an amp capable of putting over 2k watts, but it's a good bit larger than a 5-lb micro head.
But this does raise a good point in that the power supply technology (SMPS) is just as big of a factor as the output section technology (class-D) in this equation. |

TD | +1 Also, the Markbass all tube amp, from what I understand.
To me, SMPS is the big game changer, not the class of power amp.
The Carvin B2000 is another example of a super powerful amp in a very lightweight format that has a class A/B power amp but SMPS. |

Something is strange about that one from what I remember... maybe just that autobiasing thing or something. Might be just misremembering the spec. |

The controls do include auto-biasing per tube, but it does a lot more. Tom Lees did a full technical review in issue #2. This is a super cool head, and while it didn't catch on like wildfire, it's still a milestone in amplification technology, in my book. |

TD | You wouldn't happen to work in the IT field? Where I work SMTP = "Simple Mail Transport Protocol". Not a very common thing to find in bass amps...
SMPS = "Switch Mode Power Supply".
