Best Server To Run Roon Core

@jaytor thank you for sharing this. This is great.

I just have some questions:

Is the main purpose of the Gaia DDC to re-clock or anything else?
Also, I am not familiar with the economics of the Gaia DDC vs the Bryston Streamer. Was your main motivation to sell your Bryston because it was more expensive than the DDC or some other reason? I ask this because in essence (if I understood you correctly), it sounds like by adding the DD converter, it enabled you to remove the external streamer.

Thank you

The Gaia does a few things.

It can convert virtually any input type to virtually any output type, so you can optimize the connections to your devices based on what works best and what cables you have available. 

It isolates the inputs from the outputs and removes a lot of the noise. 

It has extremely high quality oven-controlled femto oscillators (comparable to what you'd find in the best streamers and dacs) so that the signal delivered to the DAC is as clean and jitter free as possible. It can also sync to an external clock if you use a master clock source, or if your DAC can output clocks (like my Denafrips Terminator Plus). 

If purchased new, the Gaia is about $1700 (price adjusts based on exchange rate with Singapore dollars). The current model Bryston streamer (BDP-3) sells for $4100. Mine was the previous model, although used the same output board as the BDP-3. So as a Roon endpoint, it was equivalent. 

My main motivation for purchasing the Gaia was to have a way to use i2s with my DAC (which at the time was the Denafrips Terminator - since upgraded to the Terminator Plus). I had read that i2s worked best with the DAC. I had not intended to sell the Bryston when I bought it, but I found that connecting directly to the Roon server via USB worked at least as good (I think maybe better, but the difference is very subtle). 

Using i2s from the Gaia to the Terminator made a very noticeable difference in sound quality. I haven't had a chance to compare other inputs on the Terminator Plus (I've only had the new DAC for a few weeks).

I'm using fairly nice cables for the USB and i2s connections (Audioquest Diamond USB and Tubulus Argentus HDMI/i2s). But I initially connected the Gaia to the Terminator using a cheap generic HDMI cable ($12 from Amazon) and even with this cable, the difference was significant compared to using other inputs connections.

I think you could be disappointed going from an Aurender N10 with the Conductor app to a Roon-based system.

I have an Innuos Zenith Mk. 3, upon which I was running Roon Core. At the suggestion of another member, I tried Squeezebox using Ipeng as a remote. The sound was significantly better; the music was clearer, the background was quieter and there was greater dimension.

The results were pretty shocking and somewhat disappointing because I really love the Roon UI and the Ipeng UI is nowhere near as easy to use or full featured.

I’d be curious to hear if other folks have had a similar experience.

When I had my Zenith Mk3 and before the most recent Roon updates I was running my Zenith in Roon plus Squeezlite (experimental) and I agree Squeezlite and Squeezebox sounded really good. Maybe better than Roon. But I didn’t have to use iPeng thank goodness. I don’t think iPeng is very user friendly. But things went haywire with the Roon updates. I had to switch to plain Roon core, which was much better. But I sense that the Innuos strained with upsampling and DSD. So I sold the Zenith. I am going to experiment on the low cost end with an Azulle mini PC which will cost me $613.47 to build. If that doesn’t go well I plan to get an SGC SonicTransporter i5.

My Zenith replaced a SonicTransporter i5, SGC LPS and Synology NAS.

In my humble opinion, the Zenith is audibly better. In all fairness, the SGC ran the Roon DSP features without issue. 

The other thing to note is that the SGC i5 is not a streamer, just a Roon Core server whereas the Zenith can act as either or both.
