Well, I use LInux/MPD, but I tried soxr and src like 15 years ago, did the upsampling offline and played them than straight from NAS and tried to compare...could not really feel like this was an improvement...different, yes...but maybe with this new software and my new DAC I will try this experiment again...Is this the setting you recommend ?
I cant really recommend any setting for you. Im not an EE and digital filter theory is way complex. Besides we all have different gear and sound signature preferences.
All I can say for me is depending on the DAC, system and ears, filters can make no difference or be a significant upgrade.
If you can run Foobar in Windoze with the best setting, have a NOS DAC or a DAC that responds to OS-filters and enjoy DIY "tinkering" then why not try PGGB? You mentioned trying SOX so I mentioned that SOX in Resampler-V is highly configurable and posted the screen shot to show all the options.
Unlike most DIY theres no cost and no soldering fumes trying PGGB 🙂

Free new PGGB-RT 64-bit Foobar2000 plug-in module released. (RT=Real-Time)
A new free foobar2000 higher-precision (64bit) plug-in component has just been released. According to Remastero, it utilizes more advanced processing algorithms than before, which feature both improved resampling and noise-shaping. It's completely free, and the only limitation is that it does not permit you to convert/save resampled tracks. Link below.

Additionally, Zaphod, author of the PGGB, says he will respond to questions either on the foobar component thread: Remastero's foo_pggb_rt, a 64 bit Foobar2000 component for resampling (hydrogenaud.io)
Or on AS forum:

Thanks for the update. I'm going to try this.
The older PGGB has made significant improvements for my listening.

Kazap, I’m curious as to the DAC configuration you are using with the PGGB software upsampler. Is it configured internally (within the DAC box) as an NOS DAC?
I use a Denafrips DAC. I put it in NOS mode so there are no filters and use PGGB at 1411 rate to try and defeat the the Denafrips interpolation. PGGB sounds great.
I'm not very familiar with the operation of the Denafrips DAC, other than that it features a discrete D/A section, and is NOS capable. If the DAC is in NOS mode, is there still reason to be concerned that it may interpolate the data?
Denafrips independent measurements show upsampling to 32x in all modes.
PGGB is one of the few options to do great x32 and works very well with Denafrips for me.
Denafrips have one of the more affordable R2R DADs that measures pretty well and sounds particularly rich in timbe. PGGB takes that up a level.

FYI-
ZB, author of the PGGB resampling software, has announced the release of an improved version of the PGGB-RT, free, plug-in module:
PGGB V7 (The Lite Edition)
A Thanksgiving Update (Free, Perpetual PGGB 64bit and 107bit Processing for PCM Output):
I just released an update v7.1,42 you can grab it here.
What has changed?
During trial period and after the trial period ends, PGGB will now allow both 64bit and 107bit precision processing for PCM output perpetually without any restriction! As in 64/107bit precision for PCM will be free going forward. This is PGGB 'Lite', our way of giving back to this community and allowing more audio enthusiast to experience PGGB offline upsampling without restrictions. In terms of reconstruction accuracy, PGGB has come a long way since its release 4 years back. Call it trickle down, the current 107bit processing is more accurate than PGGB-AP 192bit precision released in 2022 and we are happy to share it for free with this community.
107bit processing uses double-double to takes advantage of CPU instructions for faster processing, while not as accurate as the current 128bit processing for PCM, it comes close and does that at about 2.2x faster speed than 128bit processing.
Why is this relevant to foo_pggb_rt?
We will soon release the free foobar2000 PGGB-RT plugin that will support both 64bit and 107bit precision processing for PCM output as we feel 107bit processing is fast enough now to allow real-time upsampling on modern processors, this will be the first time >104-bit end-to-end, processing is being done for PCM upsampling in real-time with quantization. noise in audible range and stop-band attenuation as low as -500dB.
PGGB Lite will allow you to test if your system meets the requirements for real-time processing at both 64bit and 107bit precisions. If you set the logging to any level other than None, you will be able to open pggb_batch_analysis_v7.csv or pggb_album_analysis_v7.csv and look at 'Time Ratio' which is the ratio of the track length to the processing time, you want this number to be 2 or more.
107bit processing does need 2x the memory for 64bit processing, 16GB or more RAM is recommended.
