BAM Posted September 29 Share Posted September 29 I have a Apply TV. I have recently read of upgrades to Apple TV relating to power supply. I have had some experience with linear power supplies always giving better results vs a switch mode power supply. The power supply cannot be very substantial but does seem to do the job. Has any one tried a Roku with a good linear supply? Link to comment Share on other sites More sharing options...

BAM Posted Tuesday at 02:02 AM Author Share Posted Tuesday at 02:02 AM I already have a Antipodes 12v linear power supply so to buy a Roku for the experiment is not a big investment. Will report my findings. Link to comment Share on other sites More sharing options...
Snoopy8 Posted Tuesday at 03:18 AM Share Posted Tuesday at 03:18 AM My experience suggests that better HDMI has more impact than a linear power supply on the audio of media players. The impact of a LPS was marginal on a Dune media player. The Dune, using standard power supply and with better HDMI, beat 2 different Zidoo media players, one with a better power supply. Similar reports on Zidoo forum that models with better HDMI (Neo models, Z3000 Pro, UHD8000) produced better audio. Yes, results are not for the Roku, but would not be surprised if a LPS gives only minimal improvement. Link to comment Share on other sites More sharing options...
BAM Posted Tuesday at 08:20 AM Author Share Posted Tuesday at 08:20 AM I am not expecting any major improvement. I have a Ziddo UHD 3000 which equals or beats my Oppo player. Streaming 4k movies do not compare but there is hope. Upgrade my HDMI cables. Maybe the cable upgrade will improve my Apple TV. I still suspect linear power supply will improve audio.

The Zidoo UHD 3000 is supposed to have a better power supply but still lost to my Dune Real Vision 4K in audio. Video was about the same. Video on Oppo 203 was behind both because it used an older Realtek chip, audio about the same as Zidoo. SQ is largely influenced by HDMI, not power supply. As long as HDMI cables are HDMI 2.0/2.1 compliant, could not find a difference by changing them. If you want better video and audio, suggest the Zidoo Z3000 Pro or UHD9000.

I probably will upgrade my Zidoo in the future. I did originally looked at the Dune. Made in Russia so no. 1 Link to comment Share on other sites More sharing options...
Steever Posted Tuesday at 11:08 AM Share Posted Tuesday at 11:08 AM (edited) BAM, where in the fine state of Qld are you situated? Im in Yeronga in Brisbane and have a 12VDC modded ATV 4K (A1842) we could try if you’re local. Message me if you want. I also have a pretty decent Wireworld Silver Starlight 5 HDMI cable we can swap in and out. Edited Tuesday at 11:19 AM by Steever Link to comment Share on other sites More sharing options...
