Thanks Jussi for the quick response! 
I will try your suggestion.
Do you happen to have suggestions for filters and other settings for Denafrips DACs?
Greatly appreciate your help!
I would stick to highest PCM or DSD rate you can do.
For PCM, setting DAC Bits to 20 bits and using LNS15 noise-shaped dither works well.
For SDM (DSD) output, your choice of ASDM7EC modulators at highest possible rate. For example DSD1024 with ASDM7EC-ul or ASDM7EC-light is already a good choice.
Digital filter depends on the source content and your personal preferences/sensitivities. Default ones are very good general purpose ones for wide variety of source content. But I would recommend to take a look at the filter table in the manual for some rough (and certainly not definitive) suggestions on what could work.
Really appreciate your suggestions.
A few follow up questions, sorry for many questions from the noob 
, hopefully it’s ok.
Where should I configure the HQP settings in my setup: on the server, on the client (Surface) or both?
Where should I point Roon to the server or client?
Do I need to install Roon client on the server? Currently I have it on the client.
Thank you in advance!
One more thing forgot to ask, does the server have to be on the same subnet as client?
TIA
I figured out the answers to my questions. Please disregard my previous questions.
I would appreciate best recommendations for the following settings for the Denafrips Enyo DAC:
SDM
Integrator? I have it set to FIR2
Conversion? Set to XFi
Advanced
CPU
E-core allocation? I have Intel i5-8400 2.80GHz with 6 cores, now set to default
Processing
DSP pipelines? Set to default
Blocks per cycle? Default
Idle time? Disabled
FFT filter length? 512
Finally, I would appreciate recommendation on best Denafrips driver settings.
Currently I have this:
This is good choice and what I personally use.
This 8th Gen CPU doesn’t have E-cores, those were introduced on 12th Gen. So that CPU has only P-cores. So you can leave the setting as “Default”.
You can save some RAM by setting it to 2 if you use only stereo and you don’t do anything more complex with the HQPlayer’s matrix processor. (default is 128)
This is to fine tune optimal performance out of your computer. You can leave it at default.
When using Roon as source, it is strongly recommended to set this to something like 10 seconds at least. I personally use 30 seconds. This makes interaction with Roon a lot snappier.
No need to touch this default unless you have a very specific reason to do so (and use “FFT” filter).
It is best to set the buffer size to highest possible value. 14.5 ms of buffer is not much for Windows, so a bit of extra activity on the computer may lead to dropouts in audio. It matters especially for the higher output rates.
Thanks Jussi I will set these settings as per your recommendations.
Really appreciate your help on this!
