Hi Tony..you should hear the Patek on a speaker with no crossovers and a fair impedance. Believe me ..the amplifer is extremely transparent when not bogged down by crossovers and wild impedance swings. I would expect the D-225 to come out on top where more power and heavy load capabilities are needed. I'm confident the results would have been the opposite on the proper speaker matching. This would be like me comparing a SET 10 wpc to a 500 wpc Pass amplifier on 88dB speakers that are 4 ohms..the winner is obvious. LOL
Cheers
