No, I don’t have Hapi anymore
Linear-phase sharp roll-off non-apodizing is best choice when the source is HQPlayer and has already gone through filters there.
DSD256 or 352.8/384k PCM, it is up to your choice. I was using DSD256.
My understanding is that it helps a little bit in cpu resource to upsample 44.1 source to 44.1x dsd and 48k source to 48x dsd. With my cyan 2, I have enabled 48x dsd and checked adaptive rate so it does exactly that - 44.1 source to 44.1x dsd and 48 source to 48x dsd
If your computer has enough resources, and your dac does not support 48k dsd just upsample everything to 44.1x dsd it’s totally fine with no impact on sound
I just received the iFi Zen DAC Signature v2 and it does support DSDx48.

That’s good to know they dealt with this in their newer dacs.
Nice to read that! I’m looking for a true direct DSD dac and I’m happy to discover ifi dac
But is it PCM 32/384 and DSD256 max?
Thanks so much for info
Gerardo
Specs say PCM384/DSD256 and I haven’t tried above DSD256. x48 works with exactly the same presets which I use for my speaker setup with T+A DAC200. I got Zen DAC Signature v2 for the headphone setup.
Ok,
Thanks for info

I almost pulled the trigger on the ifi Pro iDSD Signature but sadly no Roon support.
Ignore the streamer/network function it still is a great dac with a great hp amp
It is not a clean DAC. It is more likely to have ‘a sound’ than SMSL D-6.
Due to much higher noise and distortion.
HQPlayer might help a bit , but unlike D-6, it doesn’t start well (analogue output).
Personally I don’t want my DAC to have it’s own sound (as much as practically possible anyway) - I leave that to headphones and speakers.

This is what I found as measurements with the updated firmware version of the PRO IDSD
iFi IDSD PRO 4.4mm Pentaconn Edition firmware version 2.15 JITTER RESULTS
24 bit / 44khz Jitter Measurement - 60 picoseconds peak - 13 picoseconds RMS
THD= 0.0008% at 1khz , THD+N= 0.001% SOLID STATE MODE. I WOULD TO LIKE TO POINT OUT HERE, THAT AFTER THE ADDITION OF THE E1DA SCALER, THERE ARE SOME NOTEWORTHY CHANGES BE MADE. Total Harmonic Distortion is clarified to be -106db, and Total Harmonic Distortion +Noise is now clarified to be -101db, which of course makes sinad 101db!
EXCELLENT Noise Level and Dynamic Range in all THREE analog output modes
Frequency Response SS (from 20hz to 20khz), dB: L -1.11db, +0.02 R -1.11db, + 0.02db
THD: 0.0008%
THD+N: 0.001%
IMD 19khz+20khz: -100.7dB
LINEARITY -100dB: +/- 0.01dB
LINEARITY -115dB: +/- 0.75dB
LINEARITY -117dB +/- -1.5dB
Native DSD64 - THD+N -99db
Native DSD128 - THD+N -99db
Native DSD256- THD+N -99db. Consistently maintained Analog SINAD output at approx. 99dB at DSD64, DSD128, and DSD256

Yes maybe 8 years ago this would have been good.
I think Neo iDSD is better performer at much cheaper price.
Then you compare SMSL D-6

Well I look forward to seeing some measurements on the neo, but I doubt the neo would be much better performer having previously own both the Neo and the pro
But that’s why I would be buying it. For any network dac to not have Roon capabilities in 2024 is pretty stupid.
Your doubt comes from listening, not measuring.
My doubt comes from seeing Jussi’s Neo iDSD measurements and having owned Pro iDSD myself 
When I talk about cleaner analogue output, I am of course talking about measurements…

Yup could very well be just another case of something measure better does not sound better.
I had both the Neo and the pro in the same system for months before selling the Neo
It could be that or… could be a preference for more noise/distortion of DAC.
It would not be the first time in the history of this hobby.
I don’t mind personal preference - I wish people would just be open.
One of my favourite sounding rigs was Playback Designs Merlot as both DAC and headamp - and it doesn’t measure as great as my current rig. I thoroughly enjoyed it, even if I enjoy current headphones rig more right now.
I didn’t enjoy Pro iDSD though, something sounded off.

Compared to the Cyan 2, I love them both. To me It would be a tie for me.
The Cyan 2 sounds more neutral, organic, natural, believable.
The ifi pro sounds more musical, warmer, a bit more coloured. With a pair of great nos WE396a tubes, music can sound unbelievably beautiful, then next thing you realize it’s too beautiful it’s unreal… with or without the tubes, the ifi pro does hit a bit harder in bass and has a wider soundstage but the Cyan 2 is more precise in its imaging.

Actually the ifi pro is upnp/Dlna compliant so you can easily just use jplay iOS or mconnect or bubble upnp to stream music to the pro directly…
THD of NEO at DSD256 is primarily 2nd harmonic with very few higher harmonics (which is a good thing) and overall clean output. So I don’t expect it to have any sonic problems and that is also my experience with it.
Now there’s a second generation NEO where they claim to have improved analog stage, but I don’t have it at least yet, so I don’t know how it performs in comparison.
