Prima Luna Vs Accupahse

Focals and Tannoys are very different sounding speakers, so if you buy an amp now that sounds good with the Focals you may be disappointed with the synergy with the Tannoys.  Upgrade the speakers first if that’s where you’re headed and then work on the amp. 

Out of both amps which one would you say is the better amp. I want to take my system to the next level.

Hard to recommend any amp without knowing what specific improvements you’re looking for over your Arcam and what sound characteristics (i.e. imaging/3D soundstage, tonality, treble detail/air, micro/macro dynamics, PRaT, etc.) are most important to you.  “Better” and “next level” are pretty vague and can mean very different things to different people depending on their personal tastes/preferences.  So more specifics would be very helpful here.
