I have the same dilemma as Anonymoustao. Maybe I could stretch for a stock OR5 but I am not sure how much better than a AP2 w/battery it is going to be. Almost every reviewer seem to have theirs upgraded with turboclock and hynes regulator (The J Kenny is out for me because of the audio delay with video). Further, the reviews implies that the OR is less effective with well designed dacs.
Given all this, I am thinking that maybe make more sense to sell the Octave and combine the money to buy a better DAC with input less susceptible to jitter. Maybe even sell the preamp as well and get a dac with a well implemented volume control/remote. Many options available including Antelope Zodiac, Berkeley Alpha or maybe even an Empirical Overdrive.
