Wouaww ; that is very rare ... i think there are only few owners of SPA-8 amplifier in the world !Bro , I recently got my SPA8 amp and it is simply crazy and magical sounds ! you have to get one !
I have heard this big amplifier at Munich when Playback Designs have made a demo of this model for the first time ... it was in combination with Stenheim speakers (it was in 2018 if my memory is good) ; the sound was really great : very fluid ; not the typical sound from very big / very powerfull solid state amplifiers.
Could you tell us more about the sound & performance of this SPA-8 amplifier into your system ?
Do you have already created a post here on the subject of this amplifier ?
