New photos of Randy's system ...

Not sure how high Roon goes, however I do know that HQ Player sounds better. I had tried upsampling with Roon and it was good, but not a big improvement. HQ Player has blown me away!

Randy-
So glad you are enjoying the T+A DAC8dsd...it's a special piece.

As a heads up, for those that want to stop short of HQ Player but want DSD512...Roon now offers their very own DSP engine with a nice set of filters. I was interested in a one stop shop and am doing it all in Roon. Sounds awesome!

i assume mac users are still limited to dsd128 because of DoP -- or has that now somehow changed?
 
There is no max DSD rate based on OS. DOP is completely dependent on the maximum PCM input a DAC can do. You need double the equivalent PCM to deliver DSD DOP.

DSD64 PCM equivalent is 88.2 so PCM 176.4 at least is required to deliver it DOP.
DSD128 PCM equivalent is 176.4 so PCM 352.8 at least is required to deliver it DOP.
DSD256 PCM equivalent is 352.8 so PCM 705.6 at least is required to deliver it DOP.
DSD512 PCM equivalent is 705.6 so PCM 1411.2 at least would be required to deliver it DOP. Of course this doesn't exist in any DAC that I know of so you can't do DSD512 DOP.

thanks for this explanation. given my dac8 dsd maxes out at pcm 384, dsd128 is the most i can do with a mac and this correlates with the owners manual on this issue.

...looks like a diy NUC w/ ROCK or a nucleus+

Yes, mac/Linux users are still capped at dsd256.

Linux is not limited to 128. Its the firmware in the amanero in the Dac8 that is limited. The Amanero in the Lampi is flashable and can do 512. T+8 would need to do a hardware change to allow for the firmware update. Not sure you can have both Windows and Linux at 512 at the same time.
 
So latest update to my system.... I am trading the Bryston Headphone Amp to my buddy... I don't use it much and the headphone amp built into the T+A DAC9 DSD seems to do all that I need for occasional headphone listening. I am getting a couple nice cable additions to my system. Getting the AQ Earth XLR interconnects which I have been using. Excellent improvement in the system. Also getting another set of Kimber Kables and will do true bi-wiring on my KEF's (the PS Audio amps also have this capability). We are also gonna include what I still owe him for power cables. All in all a nice deal for both of us and adding some refinement to my system.

I also added a classic Technics tuner that I got for cheap. It is the same one I had back in the day and always felt it was one of the better tuners ever. In pretty decent shape for how old it is and it sounds a ton better than the McIntosh tuner I recently moved during other gear change outs :)....
 
I have had a few people ask me about my HQPlayer settings and how I get it to up-sample all my music to DSD512. The following screen shots are my settings. I have Roon and HQPlayer both running on my computer/custom built Windows 10 Pro Server. Roon is the controller and user interface, HQPlayer handels up-sampling and is the playback engine. Everything I have is up-sampled to 24.6! This is DSD512 with a base clock of 48.... I am hoping that these screenies make since and give the answers to your questions...

Randy...thank you for the screen shots...super helpful. Is there a way to disable the volume knob on the main HQ player screen? Or do you just keep it on max?
 
Not sure on that one. I never use the HQPlayer GUI. I only change the settings; filters, etc... All controls and interfacing are done through Roon. By setting the Min and Max output to the same number I have effectively defeated HQPlayers volume control. I set both a bit negative which gives my pre-amp more range of control for lower level listening.
 
Looks sweet, Randy! The new T+A amp fits in great with the DAC and the rest of the system.
