Is this a power amp I see before me?
No itās an Impassive Aktiv passive crossover.

Yes, I understand that, but the text which announced its arrival stated āpower amplifierā in the singular. So I assume that aside from no power supply being required, it works in the same way as the SNAXO.

Agreed. The text is misleading as it mentions only one power amplifier:
āNeither nor truly passive - SIGAO DRIVE is an external crossover with no power supply, situated in front of the power amplifier in the audio signal chain.ā

I am a bit lost as well. With classic thinking - how should a crossover work without power supply?
More passive - two boxes outside LSā¦ noā¦ or?
We will see - interesting and a good place for speculations 
The crossover derives itās energy out of the music signal, hence another benefit of going active ā¦
Yesā¦. The absence of a power supply for the crossover seems to be the key bit, from further reading on the Kudos web site. I guess that means it has no power lead socket or connection to an external PS - unlike SNAXO, or (I assume) active crossovers from other manufacturers.
No matter. It still means additional shelves for an extra amplifier and the crossover device, for which I have no room. My 606ās will remain passive.
Am tempted to replace my 250DR with a 250NC, for the extra power, but would need to test at home to see if this would change the character of the system, the rest being old classic (252/SCDR), NDX2/XPSDR.
I donāt relish the prospect of packing up those boxes in order to recreate my system in a dealers showroom.
Iāve been waiting for this for about a year and likely wonāt be buying it now.
Main reason the priceā¦Ā£6k !!!
I wish they did a more affordable powered / shoe-box model.

RCAs in, RCA and DIN out.
Perhaps I should have just bought a second 250. Not enough rack space for four 350s 
Interesting approach anyway. Good on Kudos for bringing this solution to market.

Is this not ājustā a passive (as in non-powered) line-level crossover? Those exist already.
Which is more than youād spend for the now defunct SNAXO plus power supply, or the Exposure solution. You really have to believe in passive signal processing to go for this.
Naturally, the proof will be the sound. Iād be curious to compare it to the SNAXO/SC solution I currently use, but Iām not particularly in a hurry for that.

Not if you got a supercap. I think itās less actually
I just saw it and heard it. Give it a listen, you may well love it.
