Rega DAC problems

My Blu Ray Player is connected by coax to the Rega DAC and shows 44.1-48k with Blu Ray Audio as I stated but Redbook CD's played on that player show 88.2-96k and I know they are 44.1. I think the Player is upsampling as I have a Logitech Squeezebox Touch and Denon universal Player connected to the DAC with Coax and Toslink and my ripped CD's (FLAC) and Redbook CD's show 44.1 when played on those devices. My Hi-Res files from HD Tracks and Qobuz show 88.2-96k as they should when played through the DAC from my Squeezebox.
I will try and find out more and report any findings.

Thanks for your interest and effort. I've always felt ripped-off that I couldn't playback hi-res from my Oppo. It would be interesting to know if 192/24 downloads would lock-on to player.

I can't try that out as my Squeezebox Touch only supports 24/96 and below and downsamples 24/192 to 24/96.
I hear you though as I picked up the Rega DAC for all it's inputs and Blu Ray Audio, SACD and DVD-Audio won't benefit from these connections to the DAC. Very frustrating indeed! 

Anyone issues with 88.2KHz sample rate on the rega dac?

@craoul79 Yes! When I try playing anything with 88.2kHz sample frequency, it comes out horribly distorted. And it's not a cable capacity problem, because it works fine if I upsample to 96kHz. I tried with both 16- and 24-bit width, and 88.2kHz is a problem in both.

Did you ever find out anything more about this?
