Dear Arwp: I respect the Atmasphere asumption that the 8's are designed to favor tubes but IMHO that assumption could be a " little " controversial ( for say the least ) due that the 8's has a complex electrical impedance curve that goes so low like 2.2 Ohms that always for any tube amplifier represent a very high target that the tube unit can't achieve ( fully " calm " ) making a degradation ( distortion/colorations ) to the audio signal, this does not happen with SS units like the one you own.
Even MR. Atkinson ( that like Atmasphere has a top knowledge on the subject ) in the Stereophile 8's review made this comment about:
" However, and also like its predecessors, the WATT/Puppy 8's impedance characteristic demands the use of an amplifier that can deliver generous amounts of current. " adding:
" It is definitely a difficult load for an amplifier to drive,........The Wilson did sound superb driven by Ayre MX-R monoblocks on both of the occasions I listened seriously to it in Wes's room. ""
No, I don't want to start any " argue " on the subject with Atmasphere, it is only a different opinion: IMHO I think SS is the best way to go with the 8's but of course any one else could think different.
Regards and enjoy the music.
