Got done reading through the thread. Interesting that this guy has the same DAC chip(BB PCM) as Fiio X5. Of course I expect better ui from Cowon, and audio affect options.
I've also looked at X5 specs, and the P1 has magnitude lower THD+N and higher SNR(probably due to taking measurements without load). Also, the spec'd values are slightly better than AK240, except the AK's balanced specs, but SNR is better over all. Also interms of crosstalk, the P1's value is same as the AK240's balanced. That's P1's single ended has the same crosstalk value as the AK240's balanced output. They do have screenshots of the values measured, so their values could be legit. Looking at the specs for all the AK players, they pretty much have identical SNR and THD+N. Except the AK10 which is magnitude higher.
I'm guessing the THD+N values of P1 and the AK series are without load as the DX90 shows .0015 with 32ohm load.
Anybody know if there has been measurements done on the AK240 or any of the AK series? I would like to find out if their specs are for real, would be useful for values with load.
In all, their measurements are pretty much identical to AK series player, but lacks balanced if that is something that one feels puts out better SQ(but again the crosstalk values are the same even if P1 is single ended).
Hope yall can provide some subjective sound comparisons to X5 and AK series players.
