I have a 9300, it's OK, but…
The EPG is really slow to load…I don't accept the power saving argument, my LG TV loads the EPG on powerup, in is many times faster than the Humax. Realistically I have to switch the Humax on 10mins before programming for a weeks recording.
The remote is pants, several of the most important functions are under the slidey flap and are on tiny buttons.
There is a bit of fan noise on startup, but only for a few seconds. otherwise it's quiet.
The HDMI output is pretty soft. I looked into it on the Humax forum , and the opinion appeared to be that it was best to use SCART/RGB, as the upscaling is not the best. I would have gone for the cheaper non-HDMI version if I had known.
Humax have a pretty good reputation, but as far as I can tell, the 9300 is OK, but nothing special…dunno if there is anything better out there?
