D400 power output at 8 ohms

[Confused]

I cannot answer the question definitively, but I do think I have some relevant experience. Back in 2013 I listened to the KEF Blades for the first time, this was a demo with what was then the D240. This was a good demonstration, everything sounded excellent. Following this I auditioned a variety of amplifiers, many at a higher cost, and could find nothing that I preferred to the Devialet. About six months after that first demo of the Blades plus the D240, this is what I ultimately bought. The thing that is relevant here is that one thing I tried with the Blades was what was then the D170. This was a terrible audition, a complete loss of dynamics, bass control, many things. Of all the things I tried with the Blades, the D170 was easily the worst, a far bigger difference from the D240 than the loss of 70 watts would suggest, curious when the D240 was for me by far the best. The D200 is of course a D170 with a firmware update, and the D400 is a superior beast to the D240. So it looks to me that there is a threshold somewhere, if you have a speaker that the Devialet struggles with, the results can be bad, but move up the Devialet range to the point you cross that threshold, then the difference is transformative.

Would the D400 be enough to take the Triangles beyond that threshold? My guess is yes, comfortably. Other points to note, the Blades dip to 3.2 ohms minimum and have four 9" bass drivers per side, and these are bass drivers with unusually large voice coils for their 9" size. Looking at on paper data is a notoriously dangerous thing to do with hifi, but on balance, I would say the Blades look the slightly tricker load. The D240 is also 160w less powerful than the D400. There is a good chance a D400 would drive them perfectly I would say. Of course, there is no substitute for trying this for real, but we are all agreed on that point!

As an open question, has anyone ever found a speaker that the D400 cannot drive?
