I can think of couple of ways to make IIR2 more feasible for high rates without excessive load. I will add this to my thinking list…

Yesssss! 
I can manage 512×48 with dc and convolution 14900KS and 4070TIS without any problems. So I believe you can do it too by overclocking.
edit. And you don’t even need to overclock as long as the cpu is adjusted correctly. I only have a P57/E45 so I don’t need anything more than normal… And balanced power mode.

Try it with Windows Server…
I have Windows 11 Pro.
You didn’t get it. 
Well, it wouldn’t even occur to me to install another OS just to try it out. But maybe I don’t understand.
34 posts were split to a new topic: HQP RAM Stability, Over / Under Clocking Discussion
Is this thread about RAM or HQP filters?
Please take this discussion to somewhere else.
Thx.
I’ve split out that discussion to its own topic.

By chance, I discovered a fantastic combination for me:
DSD1024 + AHM7EC5L + poly-sinc-gauss-long/poly-sinc-gauss-highres-lp + DAC correction.
It sounds absolutely incredible—unbelievably real, natural, and amazing.

I barely run IIR2 with 14900K in DSD256. I have to run as few things as possible. Just opening a few tabs in Chrome is enough fo stuttering for certains sources. Acc to Jussi it is CPU dependent only, no GPU rendering.
Pls. I don’t like your attitude to other members here. Those signals you sent to people, emojis, you can use at X, but not here, please. We try to help eachother. Sometimes you frustrated, I do as well, but try to breathe before posting this emojis. OK?

I’d love to hear your thoughts on how you like IIR2 compared to IIR.

I have noticed that if I shut down and restart my computer just before starting an HQ Player listening session that I get a LOT fewer dropouts at DSD512 with 7EC. Obviously even if I have closed everything else down there are proceses running that clog my procesor/GPU just enough to cause dropouts - so I imagine that if you have other programs open it similarly causes issues.

IIR is in my rig a bit lifeless, not as “elegant”. It is hard to describe really. My brain works in the way, what I perceive as close to real instruments. IIR2 give me that full body sound, but never sharp edges, and still very rapid transients. A snare edge is like a gun shot. All playback fail to give that specific transient the proper balance of a shot but still with the tiny body and harmonics, that must be there, but also end quickly. It is not just the filter. The entire rig must be equally responsive without the usual post-ringing from resonances.
IIR is good, but it is not there, as the IIR2 is.
Can’t give you any more info … sorry … music is in those tiny details more of a feeling a resemblance from my youth during rehearsal session with our garage band. Thats why modern contemporary mixes and masters are so unsexy. It simply will not unfold, but remains as a synthetic almost plastic resemblance of real music. I go often to Deep Purple - Machine Head, recorded in one take live settings and just minor additional tracks. The studio was Rollings Stones mobile, a state of the art at the time, combined with really skilled technicians. On that production, it is so easy to hear how drums, organ, guitar and bass really sound like live. That album is my reference in many aspects. Lazy, with Jon Lord (rip) is monumental. The recording dynamic range is wonderful, revealing all those tiny notes Jon did so well as well as he pompous parts. And his use of the volume pedal. This track is best at +100dB in strongest parts so that all the complex musical components not only is audible, but also felt. Glover and Paice are genious the way the make music rock and feels like thunder. It is possble to her the valve tube amps buzzing, the atmospheric sence of the hotel lobby.
It is love. I get this today with the filter IIR2 and ASDM7EC Super. But not one year ago, when my rig still was too noisy. We have vey expensive gear where I work, but I do not get that same feeling. They “sound too much”. There are more things ringing compared to reality, they will not shut up when supposed to. That is the difference, I would say.

Agree completely. I also use Fidelity software that pauses processe that does not need to run. Quite elegant software, but also some things not to do. You explain to the software, what the prioritized playback software of the computer is, in my case; RAAT Server, HQP and Roon Server. Then you hit the Fidelize button and the software pauses unnecessary processes. In the licenced version you can go deeper, but I recommend never to interfere with CPU core management, as HQP need to have 100% ownership of that.
I too start and check for any updates, then make a new restart and have set Windows to forget all previous sessions, so that nothing is weighing the clean start down. The fidelizer I use when really shutting all down and let music take me elseware, or … sorry … perhaps I mix it up with my joint … #Iduno 
Filter: IIR, ASDM7EC-fast 512+fs, SDM DSD 512x48
Impressions: high definition on transients. Harmonics are well presented and enjoyable. I recommend listening with string instruments

CPU: Demands more CPU than GPU.

Me too… PCM is the way to go with the Qutest. Jussi helped me out with my config and I also spoke to Chord about it to get confirmation. The Qutest performs best when it receives PCM 705.6 KHz… This skips the WTA1 filter. Which is good for HQPlayer is handling everything more efficiently before that point. This is also the same strategy of the Mscaler. In addition to the audible enhancements and how flexible they are. On a resource standpoint HQPlayer can more efficiently optimize the PCM stream being sent to the Qutest This being the filters, upscaling, and the respective algorithms are more efficient thus resulting in less work on the Qutest once it receives the PCM 705.6 KHz stream. Chord confirmed that the Qutest converts all DSD playback to PCM anyway. So… Jussi (and I assume many others) agree might as well have HQPlayer handle the conversion for it can do it better. Once the Qutest DAC receives this optimized PCM stream it performs its WTA2 filters and HPGA. My Qutest sounds even better with HQPlayer in front of it upscaling and applying filters. Some of my DSD files and better quality 24/192 streams sound comparable to my Rega P10 turntable. Comparable…. 
At minimum close to all of my digital streams and DSD files sound far more like analog than digital. My wife now gets confused to if I’m playing vinyl or streaming digital now… To me this is proof in the pudding! I couldn’t be any happier…
For my office I do plan to implement the Holo Audio Cyan 2. I like how it doesn’t have any filters or an DSP. And that it has bit-perfect DSD playback. In addition to this it has a separate discrete stages for PCM and DSD. With the Holo Audio Cyan 2 not having any DSP and/or filters to work around HQPlayer has a blank canvas to work with… This is how I at least understand it…
Notice: I’m far from an expert and still very green.
For my Qutest. I’ve experimented with endless filter combos, dithers, conversions, and noise filters with HQPlayer. I always go back to the below:
PCM - upscale to 705.6 KHz @ 32 bits
1x=poly-sinc-gauss-long, Nx=poly-sinc-gauss-hires-lp)
Dither: TPDF
Conversion: Poly-sinc-long
Happy streaming!

It’s a pretty interesting case sinc-Lh AHM7EC5L DSD1024 with dc and convolution. I haven’t tried it before as the corrections didn’t work at first. It seems to be even lighter than the similar 512 super 512+…
