My current equipment:
iMac (running Room Core)
NAA (raspberry Pi3 with Digi+ Hat)
Oppo 205 (Roon Ready)
Bryston Sp3 (non-Roon-ready)
I have the Rpi3/Digi combo connected to the Bryston SP3 via digital coax cable.
I have the Oppo (Roon Ready) connected via Ethernet cable
If I install HQ Player in the iMac and use HQ Player to upsample all signals to DSD, what level of DSD will I be able to use given my computer’s hardware? Here are the specs: Intel Core i7 2.93 GHz; 8 GB 1333 MHz DDR3; Graphics Card ATI Radeon HD 5750 1024 MB.
Based on what I have read, I understand that MACs are limited in the resolution that can be upsampled (only windows machines can do DSD512 for example). Would I be better off just using Roon’s upsampling capabilities and wait until I have the right equipment to run HQ Player to its full capacity?
I was considering upgrading my DAC at some point (looking at the T+A DAC 8 DSD for example). Given that my current system will not do DSD512, would buying the T+A now bring any benefit?
The Digi+ will be limited to PCM192Hz and maybe DSD64 (DoP) if your Oppo 205 accepts that over SPDIF.
In order to feed DSD512 to your Oppo 205 over the network, you need a NAA that supports it. Like a micro/ultraRendu, Allo USBridge etc. Or a Windows NAA, a NUC setup as NAA. There’s a few different options available, depending on budget.
You can try but I’ve struggled to get the Pi3 to output DSD512 over it’s USB output.
I’ve heard from one other person that the Pi3+ (the new model) can support DSD512 over WiFi (AC speeds supported). Apparently the WiFi and the USB port don’t share the same bus power in the latest Pi3+.
That’s the cheapest experiment to get DSD512 playing over the network. Just grab the latest Pi3+ and install DietPi and NAA software and setup WiFi-AC on the Pi3+ and cross your fingers it plays
I went to the DietPi Menu and launcher but could not identify the software that I need to install. Would it be something like FTP or Samba?? I did not see anything with a name NAA or similar. I just posted a question on the DietPi forum but if any knows the answer here please chime in!
I was able to find and install the NAA program within DietPi. I also followed the booting steps (thank you andybob).
However, I have not been able to find the NAA adapter as an option within HQPlayer. It might be something simple, but so far no go.
In any case, I have decided to go ahead and order a computer that can run both Roon and HQPlayer and that will allow me to upconvert my music to DSD512. I will definitely have to have the issue sorted out by then.
