@Igor_Kivritsky1 you might like to look at the processing speed indicated in the audio path window to see what that is… anything approaching low numbers under 1.5X its your processor speed and number of cores that will be bogging it down.
Suggest maybe you post the CPU model you are using so we can comment of what might be your limitations for the future. Maybe the Flux Capacitor is not needed but an i7-7700 might be 
Further to @Igor_Kivritsky1’s comments I have also done this DSD128 upsampling using an Antipodes Edge in server mode. Processing speed is 2.3x, CPU Utilisation is ~120% on quad, spread evenly across the four processors at around 30% busy on each.
So far very positive feedback from clients on the latest upsampling vs HQP and Daphile. I think we are at the point where the GUI, and efficient DSP has brought Roon on its own as a full package ahead of both Daphile, and Roon/HQP. Great job Roon team!! 
Many clients have gone from regretting the lifetime membership, to the feeling of comfort that they are in good hands with Roon.
Don’t use HQP but I have a lifetime Roon license which I have never regretted purchasing.
Some of my clients were when they were getting better sound from the freeware media player Daphile. But now the scales are tipped to the direction on Roon due to the total package.
That’s a hell of a way to give a compliment! I wonder why so many of your clients purchased a lifetime membership of something they tried and felt didn’t sound as good as they were hoping?
Never had any regrets about my lifetime membership, or the sound quality, but the DSP was certainly a welcome addition.
They got it initially to use together with HQP up-sampling because the GUI is light years better. But after finding the free Daphile software sounded better they had regrets. But now with the improvements I’m hearing positive feedback.
Do you really think roon on it’s own sounds better than roon/HQP?
I’m not sure I haven’t compared myself yet. But most of my clients just don’t like the hassle of dealing with both softwares. They want a silky smooth headless experience like you get with Daphile and ROCK. Then Daphile sounded better than HQP anyways with 90% the GUI of Roon when used with IPeng. Not to mention free. So they were happy. But now with ROCK released I recommended them trying as most are using Skull Canyon NUC based servers. What I’m hearing so far is they are content to live with Roon. However these are initial impressions. No A/B with Daphile yet.
So seems like their actual issue was that HQPlayer didn’t sound as good as Daphile then, since they weren’t outputting audio from Roon but only bought lifetime licenses to ‘front-end’ HQPlayer.
Seems like all your clients do the same thing and have the same hardware?
Roon upsampling wasn’t released until January. All of my clients are using my DAC that only runs at DSD 256, and requires software based upsampling so all sample rates at sent to the DAC at 11.289MHZ. However being a pure DSD very high resolution DAC, it’s very easy to hear the subtle differences between different SRC/SDM. And 100% of them chose Daphile as superior sounding vs HQP. The first generation Roon upsampling was a disappointment for me and a couple of clients who tried. But after the Roon team implemented my suggested changes, it’s a different story now. Another golden example how constructive criticism is a win win for all.
Thanks on behalf of all Roon users for your constructive feedback and for making Roon better for everyone. 
Yes the fanboys revolted with their torches and pitchforks (most deleted) but in the end what they were fighting benefited them as well. Sure is ironic how that works
The irony indeed!
Pretty sure that this is an impossible question to answer, that they sound different is probably very easy to hear (one assumes) but surely it is a very individual thing as to which sounds ‘better’
Nick,
When I say it sounds better, then I imply it sounds better to me in my system(s).
I thought it should be a given, that it’s my personal Impression.
Then no-one else can answer your question.
When other 20 people say, they prefer roon/HQPlayer over roon alone, maybe there is some (individual) sonic gain behind it 
I understand, when people say roon/HQPlayer is too much of a hassle for them but that roon alone sounds better, that I find hard to believe
Understood, I did have a listen to HQPlayer once and did not like it. Much prefer my digital to sound digital 
I hope your denigrating of HQP is not a result of your heated discussion with Jussi here:
Anyone reading this should take these statements with a grain of salt.
