I have no wish to get involved in the ongoing argument here over room measurements as I have very little experience in that area, except for a sound level meter. I did make some posts much earlier in this thread and was at the time interested in a home audition, but was unable to do so then due to some health issues.
I have now purchased a pair of Dutch & Dutch 8c's after an extended home audition of Keith's (Purite Audio's) demonstration pair and after owning my previous Meridian M10's for 35 years. It was a particularly difficult (theoretical at least) decision for me as my prime source is analogue and I was very wary of having a digital conversion taking place in my analogue chain. Would this conversion be totally transparent with the 8c's? Well in practice it's impossible to be certain really without having an identical pair of speakers without the digital conversion, but then they wouldn't be identical. All I can say is that these speakers are giving me the best sound I have had at home with both CD and LP input when fed via my Burmester 808 pre amp into the analogue inputs of the 8c's. So the 8c's are not even used in full digital mode, my MF KW25, DM25 CD player also going via my pre amp and yet CD probably shows the bigger improvement.
The ability of these speakers to remove a lot of what the room does to the sound is certainly convincing and it is only when you experience it in your own room that it becomes clear. My room is relatively small, and has always sounded reasonable to me even with my Active Meridian M10's that go quite low in the Bass, but the 8c's showed further gains can be made. Here is is what I noted down after having the demonstration pair at home for just over a week and deciding to buy a pair.
"......moving the Meridian M10's from their (the 8c's) proximity and moving them back and outwards from the M10 positions. After playing around with setup (I reset the wall distances in the app) a bit and having had quite a variety of music on them now I'm convinced they are the way to go. They are not perfect, no speaker is, and there is still a lot I love about my M10's, but when I swapped them back it was clear to me that a lot of what was going on in the Bass while not unattractive, was a colouration due to the room modes. The 8c's strip this away letting you know more of what is going on in the recording. Not always attractive, but it just sounds and feels 'right' to me. What really impresses me is the delicacy of low level sounds, inflections in vocals etc. Much more information of microphone placement etc. A friend came last night with a few of his LP's & CD's, a Audio Note 300B valve user. He was really impressed with the detail and dynamics, although I had to turn them down quite a bit for him from my usual volume (for him - I like to listen at fairly high, but not ridicules levels). He also particularly loved all the extra information in vocals. He said though while he liked them he felt he could not live long term with all that extra information. Horses for Courses."
So they will not be for everyone as is the case with everything HiFi, but for me at this time and given the size limitations of my room the best I have heard.
I want to note, as I know Keith takes some 'stick' here, that his customer service is excellent, absolutely no hard sell, infact after measuring my M10's in my room he was was not convinced I needed to change them. I had his demo pair of 8c's at home for over a week to audition with no pressure to make a decision. His had a willingness to answer a lot of (sometimes silly) questions by me both quickly and politely by both PM and phone. He also allowed me to keep the demo pair of 8c's until my pair arrived from D&D (with the latest firmware) and he set this new pair up again earlier this week in my preferred slightly revised positions, spending most part of a day here. He also gave me a generous part exchange on on my 35 year old (owned from new by me) Meridian M10's.
So "double glazing" type of salesman, from my personal experience absolutely not.
