Is there a difference in sound quality when streaming TIDAL Vs CD player


I hard wired my modem located in my family room using Cad6 cable to my Apple TV and direct wired my Apple TV to my ARCAM AVR550.  I have an OPPO 203 connected by both an RCA cable and by HDMI to my ARCAM.  

The dealer I purchased my ARCAM from told me to play my CD’s through my RCA connection and to watch DVD’s through HDMI.  If I listen to CD’s through the RCA, aren’t I using the DAC on the OPPO player rather than the DAC on my ARCAM and wouldn’t the DAC on my ARCAM be a better DAC.  My friend told me I should use a digital cable rather than an RCA to improve sound quality to utilize the DAC on my ARCAM?  If this is the case, wouldn’t the HDMI be the same as by using a specific digital cable?  I listened to my CD’s through the RCA Vs the RCA cable and I thought it sounded better through my HDMI cable.

i will be looking forward to your responses.

Thank you,

I agree with junzhang10.  I rarely listen to CD’s anymore since having TIDAL.  Can’t hear much difference.  Maybe that’s because I hard wired everything.
A simple reminder to turn off the “loudness normalization” button in the Tidal app when performing a direct comparison of Tidal to your cd playback.  Otherwise your results are automatically skewed.

Great question.

I have the "CD quality" package with Tidal but I swear that I am hearing a difference.  I will look into the "loudness normalization" button.

Part of the problem may be that I'm steaming tidal via Bluetooth with an Audioengine B1.  I'm wondering if it's a waste of money based on the method of streaming.  Would appreciate some feedback if someone else has this same situation.


When you stream Tidal, you have to choose setting to fixed or variable signal and computer decode or DAC direct. I would do fixed and external DAC decode (assume you have a good DAC and pre-amp). I like Oppo 105D Tidal app. It allows me to browse Tidal using iPad. skip cable. Also I like direct link of internet and no Wifi. Oppo 205 delete the Tidal app so i have to add a PC to stream Tidal. Less is always better to improve SQ.
I was not aware there was loudness normalization setting on TIDAL.  Not sure where to find this.  Please let me know how to do this.

When I first began streaming TIDAL I tried streaming it wirelessly via my Apple TV.  This is what TIDAL diagrams on their website.  However, my signal kept breaking up and I solved this problem by hard wiring using  CAD6 from the modem in my family room to my Apple TV and from the Apple TV to port in the back of my ARCAM.
