Bladelius "Grendel" amps

At the recent Singapore HiFi Show, I had the opportunity of listening to this Swedish amp, the Bladelius Grendel, driving the Marten Design "Coltrane" speakers. The sound was out of this world: completely grain free from top to bottom, it seemed to do everything perfectly: dynamics, air, transparency, slam, soundstaging, liquidity, the whole nine yards. Music just sounded so beautiful and lucid. Nothing else at the show even came close: Kharmas, Rockports, Sonus Faber Amati Anniversario, all paled in comparison.

The speakers, at US$50K or so, are totally beyond my reach, but the amp, at around US$8-9K seems tantalisingly tempting. My Krell FPB 300 now sounds grainy and mechanical by comparison.

Anyone had the opportunity to listen to this amp long term in a real world system?

Kind Regards
