The main reason to consider PrimaLuna is for their all tube design, engineering and overall build quality. It just what they do best. I feel that hybrid “Floyd” offering will be short lived. It’s a nice, all in one package with sufficient power, but the Accuphase (with its tone controls) will likely serve you better across your speaker evolution.
For what it’s worth, I run a pair of Tannoys (Legacy Arden) in my main system powered by the PrimaLuna Evo 300 power amp. It’s a fantastic pairing and I feel like I don’t need to consider “upgrades” in either area. Tube swaps certainly help to fine tune the sound.
Don’t rule the Tannoy Cheviot out when you start to get serious about speakers. It’s a little more affordable than the Turnberry, and the legacy line punches above its weight class sonically.
Best of luck.
