I have Qobuz and Tidal and overall prefer the sonics of Qobuz. and likely slightly prefer my files to Qobuz. I listen to lots of hirez files (I have about 17 terabytes of files). Tidal is still pretty good but I can see dropping Tidal as a possibility. time will tell.
my dac is the MSB Select II, fed by the SGM Extreme server. my dac does do MQA, which I do like mostly on Tidal, but my files are consistently better than MQA, as is Qobuz.
I have a few enhancements to my network which have made positive differences in the overall performance.
I use an MSB product called the Pro USB, which lowers noise between my server and dac. it is a box the USB plugs into which converts it to fibre then plugs that fibre directly into a fibre SFP module on the MSB dac. the Pro USB is proprietary to the latest versions of MSB dacs which are modular so can accept the proper input module.
I use fibre SFP module plugged directly into my server and then 50 feet of fibre to my network to lower noise. this really lowers the noise of the streaming and files I play from my NAS on my network.
my server uses PCIe storage with the controllers directly into the CPU which allows for improved performance compared to local SATA SSD storage or my NAS; I am expanding those PCIe drives on my server from 2 tb to 32 tb and will transfer all my files to my server.
