Bladelius-Thor mk3/Leema-Tucana 2/Norma IPA-140?

Currently have a Valve Audio Predator which has exceeded my expectations but eventually want to seek a more refined amplifier. Three "relatively" affordable European made integrated amps have garnered my interest. They all have excellent build/parts quality in addition to positive reviews. I have not heard any of these amps but did have a short demo with the first generation Leema Pulse and was impressed with its PRAT and openness despite having such a modest power rating. I can only assume the Tucana 2 is much superior. I know speaker synergy will determine which amp is best(for me) but would appreciate any comments/opinions from anyone has heard these integrated amps.
