Is using streaming services worthy of an audiophile?

Yes, streaming is legit, and no, it doesn't disqualify you from being an audiophile or a music lover; I do like the distinction, however, in an amusing way. 

We do 90% of our listening to Deezer HiFi/ Elite; Flac and it sounds good. Occasionally we do vinyl and sometimes streaming from a ripped CD or a Hi Res file. It all sounds as good or bad as the recording, mixing and mastering. I am totally convinced that the recording quality is far more important that the file type, though, MP3's are hard to make good on a revealing system.

But most importantly is access to music. Streaming and digital souces give me access to music that I would not otherwise be able to get, especially as I like a lot of music that is not available in any other form or from any other source. So, go to it. Try Deezer's high quality service (better music selection than Tidal for me and equal SQ) or Tidal or Qubuz if in Europe/ UK. It is a worthty addition to your stable of music sources. 

I tried Tidal. It sounds like a 30 year old Denon CD player. I enjoyed that CD player. It was my first, but it is not good enough for my system or ears. 

The signal is bitperfect 16/44 and stays that way if your computer or streamer is set up correctly. As you can see here even a modest Chromecast Audio can achieve that:  http://archimago.blogspot.nl/2016/02/measurements-google-chromecast-audio_27.html
So with the same DAC it should be sonically identical to CD. There is no magic in science.

Not sure just how you are transmitting your tidal signal to your system but I am getting 96 and 192 from their masters via dig coax to my Blusound vault 2 then output by single ended analog out to my McIntosh pre and it is noticeably better than Redbook CD playback.
Maybe if you were using say a smart tv to receive and using the tv analog outs to your system I could see how the sq might be poor.
I know this as it was how I first used to listen to Pandora...ok but not hifi for sure.

I still don't understand questions like 'is streaming services (namely Tidal) worthy for audiophiles'. Here's what I don't get. Streaming services like Tidal HiFi offer the same Redbook CD sample rate (44.1kHz, 16-bit) as the CDs you spin. If you believe your CD player sounds better or worse than Tidal HiFi, it's not because of the source of music.  It's usually due to the quality of your internal or external DAC chip set implementation and quality of the clock (oscillator) used to reduce jitter,

Tidal Redbook tracks and CD tracks sound the same to me when I compare using my Ayre CD player to Tidal Redbook tracks played via a Lumin S1.  The SQ difference tips in the direction of Tidal when playing MQA tracks. I already know the MQA haters will respond to this, but please only respond if you've ever listened to MQA tracks on Tidal via a decent Streamer/DAC and not a Bluesound Node 2 DAC.

If your definition of audiophile is vinyl, then I will concede that digital hasn't closed this gap, but the gap is narrowing and the convenience of digital must be considered. Pretty hard to listen to vinyl when you're driving or not in front of your 2-channel rig.
