I have not heard those, but have done extensive reading before buying my Octave, and I actually plan on getting an Audiophilleo 2, just like you. I seriously doubt you will find a significantly better sounding one-box solution for $3k. Moreover, the two units you list are very, very good ones, but dating from several years ago. This doesn't make them bad, but over the past 3 years cost/prices have come down a lot and I doubt you would getting much bang for your bucks.
Having said that, if what you enjoy is the sound of upsampling DACs, then all I said above is worthless.
BTW, do you run your AP2 directly into your Octave, without a coaxial cable in between?
