Atma-Sphere MP-3 Mk. 3.3 vs. VAC CPA-1 MK II or Avatar Super - Recommendations

I own the Atma MP-3 but when I got an Ayre KX-R, it bested the Atma.
So, I am having Ralph build me an MP-1. I expect it to give the Ayre a run for the money.
Plus, Atma Sphere is one of the nicest companies to deal with.
No experience with VAC.

@noromance : Don’t know what is passive/ active switching but compared to VAC & Atma, Shiit look like babies. No offense, but I don’t think they’re in the same calibre.
@gdnrbob: MP-1 looks impressive but I don’t think I can ever be able to afford it, even used. :)
Pound to pound, tube to tube, MP-3 seems too light, too small, & too Solid Statey compared to both the VAC models. Isn’t the sound directly proportional to the weight of the transformer & tube used?

There’s another thread comparing both Avatar models. 

@hitsofmisses Agreed. However, the reason I suggested the Schiit passive (it has an active JFET option) was because you only have two high-level sources which could be fed into power amp(s). You do not necessarily need a massive preamp or an integrated as you have the Halo. While the Schiit doesn’t look much, it is a lot better than its price suggests.

What about Linear Tube Audio, Backert, Audio Research, or Don Sachs?  Why so limited?
