I have the YBA Passion Integre. I've auditioned everything before I bought this baby. No experience with the Arcam so I can't help you, there. My review, on the Passion, is in the Archives. This amp is warm, tubelike, with all the advantages of ss. It's got it all. I owned an Integre for 7 years, and now this baby. I was going to say, if your funds are not up to this (the original Integre, possibly), but I see you're entertaining the ML and Mac. I don't want to fall into the trap, exclaiming how much better this integrated is than what you've mentioned, so let me say humbly, I liked the Passion better. A lot better. You can email me with any questions. good luck
