Holy cow, are you killing the battery yet ? LOL ? Where did you find that beefy and nice-fit power supply ?

Extremely talented guy, I have bought his own design VSON-10 to SOIC-8 Adapters with OPA1622 fitted several times before.

Not trying to be a jerk, but have you tried less solder? I have found the least amount of solder, with it just between the pin and pad, sounds the best.

You do realise the full length of that board is only about 16mm, so its all magnified, soldering looks ace to me (plus some of the tiny caps are piggy backed)

Hi folks, anyone tried any tricks to reduce the heat dissipation of the DX220 ? ie... add heat sink into the chips in DX220. Finding that my DX220 get very hot.
I have already applied the TDK noise suppressing sheets. Looking at trying out Versarien low profile heat sink.

The trick that I use is to use dx200ti and after 30 minutes of use, it is ready to boil water (no kidding).

At this point I turn to DX220ex and it appears very cool in comparison to the above.

Jokes aside, I sincerely wish that ibasso will address the heat and the poor battery life. 8-10 hours just don't cut it today.

DX220ex with amp8ex is very very good sound wise, but the above two cons severely limit its daily usage

8-10 hours is pretty good for DAPs.
