Hi PePorter
I have the Spatial Audio M4 Turbo speakers. I'd say whatever amp you have make sure that amp can handle a 4 ohm or lower load. I was powering these M4s with a restored Accuphase E202 integrated and was getting all sorts of distortion at medium to high volumes. I then tried a pair of Response Audio BellaMax 60 monoblocks that use 6C33C tubes and have 4 ohm taps as well. These monoblocks make my Spatial Audio M4s sing nicely. IME the Spatial Audio M4 Turbos also play well with Red Dragon M1000 version 1 monoblocks too.
Specs of the M4s.
