the problem i see here is besides the lack of ABX is that the robinsons are strong into class a/b so i'm guessing they just dont like class d...
this can be seen where they keep banging on with the cambridge axa25... i guarantee this is going to measure like shit... but if you like that sound then you like that sound
The Robinson's have no problem with class D amplification. They've recommended class D amps before. Your guess is what we call in the "interpretation of text" an eisegesis...reading into it ones own ideals. You would be correct if you said they have recommended more A/B amps than class D, but Andrew has been very big on Class D (especially Crown DriveCore in the past).
We have a home page post of a review of a class A amp (
Raphaelite CS30-MKII 300B), that doesn't measure well (SINAD of 22db), but the sound is enjoyed. Besides the science of physics and acoustics- the science of the mind must also be put into play (psychology). The science of life or the body (biology and auditory health), as was stated by one member - like Bo Katan Kryze, it is possible to walk both paths (objectivity and subjectivity).
I understand this is ASR and it's about the numbers - but the numbers are only used to show that a product isn't defective in its design. I listened to Amir's video on understanding speaker measurements and he states a lot of things concerning the room, where you're sitting in relation to your speakers, etc.....It's a
great watch, I see that the numbers are not the end all, they're just a start. If you noticed in Andrew's video he states that performance changed from one listening space to his current. Could it actually be the space (if you change a variable you will change a result)? His current space is much larger than his old one, and if the amp had issues pushing the Klipsch 800's to 85db (which is VERY LOUD) - it could be that the amp doesn't have the necessary power supply to do what Andrew required it to do? I'm just asking questions here.
As far as liking that sound.....Andrew does state, and this is one truth that none of us can argue with ..."Nobody has to like the sound of your stereo, but you".
Oh and I can add this....Amir really did recommend the Wilson TuneTot with equalization....almost 60% of ASR respondents gave it a headless panther.
