not that I have noticed. well not yet.
Although that is one of the things with true DSD converters... they can be picky like that. The SMSL D400 PRO with AK4191 + AK4499EX that allowed access to the AKM bypass mode (the AK 4499 series is the first that uses trimmed resistors and not switched capacitors for the DSD digital to analog conversion) was very picky with 44.1 vs 48khz rates. Anything at 48khz would actually playback at 44.1khz... yeah, it sounded like a tape with its battery running down!! HAHAHA it was kind of comical.
Clarify for me a bit.. Do you want both 44.1 and 48khz rates to all oversample to the same 'usual' DSD rates? 2.8mhz, 5.6mhz, 11.2mhz, 22.4,mhz, 44.8mhz?
Or do you just want those rates for 44.1khz based sample rates, with 48khz being 3.1mhz, 6.2mhz, 12.3mhz, 24.5,hz, etc?
The DSC2 doesn't care unlike a lot of DACs, it can do 44.1x64 and 48x64 (44.1x128 48x128) etc. etc. no problem.
My HQPlayer settings look like this and it converts both rate families with no noise issues I have yet heard. It all works for me just fine.. No strange noise issues at this time. I have NOT yet upgraded from version 5.02 though. The original version I purchased. Upgrades leave me feeling a bit leery when everything I want to do is working just fine at the time.... if it ain't broke.. yada yada yada...
So you ARE having noise issues with oversampling 44.khz rate family to DSD? I will do some experimenting and see if I can replicate.
