Well, my personal take on AKT5p vs BD T5p-II
1) Better bass for AKT5p (balanced, and AK's factory defined EQ-off) - deeper and more tight, impactfull and controlled
2) BD T5p-II is kind of more neutral vs AKT5p with EQ-off. With EQ-on and bass-performance aside - wouldnt be able to distinguish which is which in a blind test. These two points are subjective and should be taken with a grain of salt, as the AKT5p is still running in and the T5p-II was in my hands for only 15-20 minutes.
3) The price difference is quite objective though: € 760 (AKT5p) vs € 1'200 (T5p-II)
Otherwise - indeed, the cable is not detachable on the AKT5p, but the quality is there, and its balanced too. Absolutely the way to go, if you have a balanced-out/AK player.
To sum it up:
- practically the same look, feel, build & quality
- practically indistinguishable sound performance (and especially so in the targeted environmnet - when out & about), with somewhat better bass for the AKT5p
- strange pricing situation with € 500 difference in favor of the AKT5p
Cheers!
