I emailed them about it but as usual with Demeter they sort of answer my question.

I ask if it would be 2 ohm capable and they said yes. I also ask if there would be a HPF on it like QSC or Crown and they said they would think about it.... which means no. I also ask for a rough estimate on a possible range for the price and no answer on that one.

For the record, I just found a fantastic light power amp for my Demeter..... it's called a Shuttlemax! LOL! Honestly, my 201s has never sounded so good, I'm truly blown away.

Demeter is really missing the boat not putting their pre together with a lightweight class D poweramp, not sure why they don't want to make that jump with many people moving away from heavy rack systems.

It says they are using Class H which is what QSC uses in the GX7 and PLX series. I would guess a single channel Class H would be at least 12 lbs if it's 2 ohm capable going from QSC weights on the PLX 3102 which is around 21 lbs and duel channels at 1000 watts a side @ 4ohms.

You can buy a GX7 for around $600, won't do 2ohms but it will do 4ohms a side at 1000watts and is only 15.5lbs.

If they could do a relatively light weight amp single channel amp for $400-$500 it might be cool but I can't see Demeter doing that amp any less that $1000 so I don't see this making sense.

If I were them i would be working on putting out a HBP or VTBP micro with 500-1000 watts and trying to keep it under a grand.... but I don't see that happening.

I'm confused? Why does it say 1000 watt tube power amp in the copy but not on the unit. How do they get 1000 watts of tube power from such a small case?
Not a fan of having smoke blown up my shorts. ;)

I re-read that copy and see they call the amp a "Class AB /H" so I wonder if it isn't some sort of hybrid between the AB tube and Class H poweramp... Okay that could be interesting if it really cops a true tube amp vibe.....

If it is like that, Vox does something similar in their Valvetronix amps, where there's a 12AX7 working as a power tube (distinctly not as a preamp tube, before someone tries to claim that), the miniscule output of which is then amplified by a solid state amp. Hard to tell if it makes a huge difference because there's a lot of digital modeling before it in that case.

I think I read that even Jim Bergantino, who was a fan of heavy iron has moved on in his thinking.

I "think" I read? I would like to know exactly where you got that. I had a few email exchanges with Jim only a few months ago regarding the best way to power my AE112 ER's. He was unequivocally in favor of 'old school' toroidal transformer based power amps, did not like the SMPS alternatives.

Poor wording. I DID read it and it was on TB. I recall because it surprised me knowing how pro old school amps he had been and that's why I made note of it. I can't find the thread at the moment and because it was third hand I will delete my statement.

FWIW, I remember reading the exact same thing. I don't have a direct link either, but I did read it here.

If they make the claim that a 12AX7 by itself will make the power amp sound like a classic all-tube amp, then yes, that is smoke blown up the crack. But in purely technical terms, a 12AX7 can be configured as a power tube, and other brands have done this too--so they are not blowing any smoke about how it works.

Yes it can but, a 12AU7 would make a much better choice as it has the needed plate dissipation. It still doesn't make the unit a tube amp.
