Pass Labs INT 60 VS. Primaluna Dialogue Premium HP VS. Arcam A49


Tying to decide between the Pass Labs INT 60 integrated amp and the Primaluna Dialogue Premium HP integrated tube amp. I currently have the Arcam A49 which is excellent but looking for something with even more detail. All three have many excellent reviews, looking for input to make a decision. I have Wilson Audio Sasha 1 speakers, an Arcam D33 DAC, Rega Apollo-R CD, Clearaudio Performance DC turntable with a Manley Chinook phono stage.

alfa100 & leotis, I will only be able to get a demo Pass Labs INT 60, not the 150, I believe the INT 60 will perform fine with the Sasha 1, although now I have 400 watts (4 ohm) now. I had an Arcam before this with half the power & I was not happy with that. My main concern with the Pass Labs is the brightness with digital high rez files and Tidal. I have not heard this amp, just read excellent reviews. My turntable sounds great , especially with the tube phono stage (Manley Chinook). 
All this information and now a new amp choice came in to play, the T & A (Theory & Application) R2500 built on the HV platform which is close to the same price as the Pass Labs INT 60, but with more power.
