Your list of amps is wildly different. The Musical Fidelity is definitely forward/bright compared to the others. I would not ever pair it with Focals.
I don't know that Doge but the key with any pairing with Focals is the ability to deal with low impedance. Does it have 4 ohm taps? Does it deliver a lot of current or is it better with efficient speakers.
I have customers who run B&W 803 D3s and Focal Scala Utopias with 40w tube amps in small rooms. The key is room size and the ability to deliver the required current.
