Hi
@zaarog,
Unfortunately, both PD & PD 2 have
lag on startup though it is minimal & has to do with quality & quantity of music files.
If Cowon did manage to upgrade their UI implementation one day then this would make all their players almost con free but like with anything, there is always a compromise.
The question you have to ask yourself is what do you want to live with.
Granted, both processors don't have the fastest RAM implementation either which adds to this.
Having a fast SD card does help but only a little.
Otherwise playback & switching tracks is smooth & responsive during use.
PD & PD 2 support balanced 3.5 mm on the head out which means it makes it easy to power just about anything unless said head gear is above 100 ohms though it can still run most above this reasonably.
But having an external head amp to complement high impedence when necessary doesn't hurt.
On either, 3.5 hours to charge for 45 hours (PD 2) / 100 hours (PD) is still considered the most amazing in the industry.
Also there is a peusdo fast charge function built in which for every 20 mins charging not from the mains (From a computer during file transfer & maintaince), it does minimum 20 % though I believe the average is closer to 30 %.
I have the Plenue R too & while it is a good DAP, it is not as
powerful in reality as PD or PD 2 which is contrary to what it says on paper.
If the PR is in tight pocket, especially filled, on the go, the power button can still switch itself off even when locked.
I don't use it that much personally for these reasons.
As a final note on the Plenue family, it is hard for any DAP at any level to
beat the battery life on PD or PD2.
iBasso DX 120 is definitely an alternative I suggest looking at for startup speed & similar sound to PD & PD 2 though depending on head gear & source quality, there can be better staging, imaging & extension.
With the quick charge it has, 2 hours to charge for 16 hours ain't bad.
So in closing, hope this is all useful to you & if you have any more questions, feel free to ask.
Hope you have a great day !
