Can i ask what your views on your new SD800 are? Who does it compare to the LMII?
Sorry if the answer is in another thread, there seems to be a lot of MB threads these days and i loose track of things
Thanks
My LMII actually just arrived yesterday, but as it turns out, we had a band practice last night.
So, based upon one practice session (competing with drums, guitar, and amplified vocals), and playing a variety of instruments through both heads feeding a Berg HT115/HT210 stack, my very preliminary 'take them with a huge grain of salt' initial observations are as follows.
The SD800 definitely has gobs of headroom, and you do hear that, even at lower volumes. The notes just pop out with an eagerness that is quite intoxicating.

It is also a bit more 'pristine' and open sounding to my ears. The LMII has a bit more midrange mojo going on, especially in the lower mids. I like this, though with some basses I had to tweak the low-mids a bit to avoid slightly too much bloom. The LMII is punchy as heck, and plenty loud. I didn't push either head at all, volume-wise, though I did briefly explore some of their higher gain settings.

The LMII at higher volumes has that sense of fullness and just the right amount of warmth, while still remaining controlled, clear and articulate. When you switch to the SD800, though, you can't help but feel like you've just been given the reigns of a notably more powerful beast. The notes just jump out with an explosiveness that is not quite there with the LMII. The dynamics are very impressive, and I was not able to get it to a volume point where I even began to feel like I was exploring its limits (which I was able to touch on with the LMII).
Most of my testing was done with the EQ set relatively flat (or with a very small amount of high mid and treble boost), the VLE off, and the VPF at about 9 o'clock.
In short, I loved both heads (in this setting, at least), and my preference between the two actually varied from instrument to instrument. I spent a little time running them both through my Epi T-212D, and my initial 'gut-check' feeling is that the SD800 is more well suited to the Bergs, and the LMII is more well suited to the Epi cab. Suffice it to say that much testing (and much fun!) lies ahead.
Tom.
