No doubt the Aggie is darn good. It does make me a little uneasy they refuse independent published testing. I have enough respect for agedhorse's and BbbyBld's design work that have been subject to independant testing that I'm comfortable with "blind faith" in their work. All armchair IMO kind of thing and YMMV.![]()
Hey B-string, It's not that we refuse independent testing. We simply think that using average and peak measurements for power ratings creates a lot of confusion. The Tone Hammer 350 and 500 use the ICE Power 125 and 250. You can get 350 watts continuous from the TH 350 and 500 watts continuous from the TH 500. Continuous is well defined by the FTC so that there is no confusion. You measure full bandwidth at full output for five minutes minimum without shut downs. Very simple. In reality, you can do this test on our amps and they will work indefinitely under these conditions.
Rumor has it there is a TH800 coming out at this year's NAMM...Dave B., can you give us an inkling if there is indeed a new amp in the works?Hey B-string, It's not that we refuse independent testing.

You're not going to find that sort of grunt in a combo at pretty much any price, although it weighs 13lbs.
This. Sure, it's bigger, but there are a world of different power amps in the 2U form factor that slap the crap out of many mini bass amp power sections dollar for dollar.Crest Prolite 3.0

I would like to know, in your opinion, which micro head has the best power section.
Except that the OP's query was...
I'm sure the Crest is a fine power amp, but it doesn't qualify as micro. I think the OP is looking for a lightweight, small form-factor solution. The GK MB800 is 5lbs. The MB500 is 4 lbs. You could almost mount these to a pedalboard.
I'm only mentioning GK because that's what I'm most familiar with, but there are lots of other great suggestions in this thread. (In fact, I like the sound of my Navigator thru the GK power amp better than thru my larger and more powerful QSC PLX-1602. Power amps may not affect tone as much as a preamp, but it is a factor.)
Excellent heat management.
The D-class amps don't have the heat generation problem that the A and B class do. So low heat is not unusual and along with their light weight is a great advantage of Class D.
Heat is a relative thing. With enough current on the output, the power section will exceed the heat ratings of the FET's. Might not feel as hot as a lead sled---but still too hot for the components.
I've had my Acoustic Image go into thermal shut down (no fan). I'm hoping my Warwick LWA1000 can tolerate getting pushed harder--- it has a small fan, but I've yet to use it on a gig, so it's never come on.
Still, they are much cooler than class A/B amps. Didn't mean to imply they didn't need any cooling but they are night and day cooler than other types. You wouldn't even dream of building the class A/B without a fan or two to cool it.
