There’s also this thread I started a few months ago:

In th past I had an active system, with a DSP based AXO, which had some spare processong capacity which I used to dial out a few of the bigger peaks in my room, but now with different speakers and amp active is not on the cards.
What I found interesting with about the information about Linn Space Optimisation given in the current A smaller room thread was the indication that it is cleverer than just dialling out peaks, also doing other processing based on information about the room (though oddly with no actual sound analysis). Although the cost to add as a DSP box seems excessive, I did note that analogue sources can be fed through it, which may be of interest also to others: for me that would resolve a minor issue, as I prefer to run my DAC (Chord Dave) direct to power amp (MF A370), with no preamp modifying things, but when I want to use an analogue source such as when making music I have to change connections to add a pre.
