600 watt 8 ohm amp heads

Many amps are built around class D power output modules made by someone who is not the amp manufacturer.
A certain compliment of discrete output devices used in the module determine the power outputs.
The output devices and their power handling capability are determined by someone else who isn’t the output module manufacturer. The modules tend to lock in at certain power level increments that don’t usually land on 600.

 

DNA 1350 maybe.

Is there a specific reason you want 600 at 8?

If it’s because you have an 8 Ohm cab rated at 600 Watts, and you think you need an amp that matches those specs, then it’s time to do a bit more research on pairing up amps with cabs.

 

Oh yeah! I see what you mean.
I would guess that most of the 800 @ 4 class D amps will get you down around the 500-600 range.
In that range, a hundred Watts plus/minus won’t be significant for a difference in loudness.
More cabs is always good.

-edit- Looking at the Mesa D800+
800 Watts @ 4/2 and 400 @ 8.
Lots of cab options with 2 Ohm stable.
Built in HPF to help keep power from being wasted on making mud.
You can count on the power ratings to be real too.
Not Inflato-watts like some manufacturers do.
And the rest of the guts will support every bit of that power.

 

From a purely theoretical point of view, I doubt you could distinguish between a 600W and a 500W amp in practice.

 

There are at least a few coming out at NAMM that use the new ICE 1200 watt module. Many if not most of the newer Class D modules don't follow the old model of 60-70% of the 4 ohm power when run into an 8 ohm load, FWIW. 50-60% seems a lot more common these days IME.

If you want a LOT more, there's the Jule Amps 2500.

 

If you don't mind it being heavy, Ampeg SVT 6-PRO has been serving me pretty well.

 

Not 600watts but 500watts at 8 ohms is the GB SM 9.2.

900 watts at 4 ohms.

Plenty of power pushing my 210 stage monitoring rig at 8 ohms.

 

SVT4Pro is 900 @ 8 ohms bridged

 

Is 700 watts at 8 ohms ok?

 

Yeah my old 42 lb. GBE1200 was 550 at 8 ohms.
I usually ran a single 15” cab with a 3015.

 

I believe the darkglass microtubes 900 is 500 at 8ohms, 900 at 4ohms and 900 at 2ohms. Not far off from 600 at 8ohms, I went with that amp over all the others, no regrets.

 

You could always go the separate pre-amp and power amp route. I have an A.M.P. SL-1 running into a 1200 watt Carvin power amp that will do about 800 at 8 ohms. I call it my 1200 watt Thunderfunk.

 

My Epifani PS1000 will do 1000 watts 8 ohm / bridged.
