[image] Showing (off) your Roon setup - description and photos [2015-04 .. 2021-03] Uptone Audio DC conversion kit Andy, Can you clear something up for me? I use a MAC Mini, powered by an LPS @ 12VDC, that runs RoonServer. This is connected straight to my DAC after going through a DDC Hydr…

Hi Larry, The Roon reccomendations are here . Your linear power supply will be stopping line nasties getting into the MacMini. Any improvement from separating Core and Output would derive from using a small footprint Output into your DAC instead of having the Core machine directly connected. There …

Morning Andy, Thanks for the reply! I wonder what could be done with another MAC Mini I have sitting around currently unused. It’s not set up for 12 VDC but it is a i7 2.4 GHz it also does not have a SSD but that could be changed as well. I currently use my iPad for my Roon Remote but I am alwa…

Stick a little SSD in your i7 MacMini and try that as a Core into your current MacMini as Output. Be interested to hear what you think.

Andy, Even after reading your RKB about Core and Output it makes no sense to me …send a signal over RF between the two MAC minis and that will yield an improvement ??? I just can’t buy that two boxes, Multiple yards of Cat 6 cable and that added AC to power it all is going to yield an improvement…

OK. I see that you were asking how the SQ is improved, rather than how to do it. The rationale is that a direct connection to a heavy processing computer acting as Core is noisier than an Ethernet connection to a lightweight Output. It is possible to optimise a Core to reduce any difference in such …

If it sounds good to you, don’t mess with it, is a good motto to follow. :smiley:

Having recently succumbed (again) to my seemingly irresistible compulsion to fix things that aren’t (too) broken I can only agree. In my case it was the DigiOne endpoint at my girlfriend’s place. This was sounding really good (like seriously good) but had a tendency to fall over when left on over e…

The Hydra Z is a great leveller here Larry. You won’t get much improvement with a networked end point. There will be mechanical noise and heat reduction by not having the Mac in the same space but if this is already quiet you have little to gain. One thing to note however is Windows and I suspect Ma…

Henry, You are a breath of fresh air this AM!!! My Hydra Z works so well that I have not even upgraded my DAC to the new Gen 5 USB port. My whole set up is pretty quiet…I don’t hear noise, mechanical or otherwise. They only clicks I hear is from my DAC when it switches playback data rates. I…

Andy, It’s great to read stories of other folks and their soldering efforts. Getting older makes it even tougher to see what the hell you are working on and even harder to hold my dam hands steady enough :stuck_out_tongue_winking_eye: I just broke a connection my HD 800S where it hooks up to the …
