DX240 on the left with its stock AMP1 mk3 and DX220 on the right with AMP8 open. That is a bottom of pwb view:
And here is the AMP8 with faceplate already attached, facing up. That's how it looks before Vince does his 8EX magic
Tbh, while AMP1 mk3 sounds already good straight out of the box, it only comes with 3.5mm and 2.5mm ports while most of my cables 4.4mm terminated. So, I already switched DX240 to AMP8
I will go back to DX240 amp1 mk3 to have a proper burn in for review and comparison to DX220 w/amp1 mk2. But AMP8 will be used permanently with DX240.
DX240 is insanely fast, as expected, the same 3D benchsmark scores are DX300 and DX300 MAX, the same as R6 2020, R8, and RS6. It doesn't come with Google Play, but has APKPure installed, so I download Google Play and had it running within minutes. Verified MQA 16x unfolding, streaming apps run fine. SpeedTest results are crazy good, download/upload is faster than my Galaxy phone. Design is very slick, remind me a lot of DX160, just thicker with a curved back. Transparent silicone case is great, and I also received optional leather case which I absolutely love!
A few people asked me already, with DX240 out now and being compact and super fast, why even bother with DX300? Well, if you want a bigger display, that is one thing. Another one, DX240 amp card has limited room, the reason why NuTube won't fit, while DX300 has 2x more pwb room for future expansions. So, you have a choice
