A300 is flagship of Appotronics (Gungfeng) who is the owner of ALPD..
There is no way Xgimi can get a ALPD better than A300.
Not all A300 are noisy, at least my one is quite quiet.
According to HPC review, the key points A300 is definitely better than Optoma P1 (color, contrast, input lag).
P1 is a little bit brighter for RGBY color wheel used at the cost of native contrast.
P1 and A300 laser bulbs are running at the same wattage: 95W.
Basically the two color laser ALPD (A300) generate light more efficiency than one color all-white (P1). It should be brighter if they are same wattage labelled.
