sorry for the lack of capitalization and punctuation but I feel that I'm well poised to offer my opinion as to the sound quality difference between the two services.
number one and it's a big thing for me is quboz simply sounds more natural,whereas with tidal I can't help but get the feeling that somebody hit the loudness button.
like for example let's think of a song and I'm going to choose Roadhouse blues by the doors, using my audio quest DAC if I play them both back to back just switching as quickly as I can and slower as well, I can't help but get the feeling that with quboz what I'm hearing is exactly the way it sounds on vinyl. meaning that it's the way that it was recorded for example, on tidal I can't help but get the feeling that and we're talking with the MQA disengaged, that the sound is deliberately spread out soundstage wise and you get this sense of like I said somebody hit the loudness button.
of course it's not only that, for me another thing is MQA, I was listening to James Taylor and a lot of his albums are available on tidal in mqa. well I'm listening to the song something in the way she moves, and on quboz what I'm hearing is, and we're talking about high res 192/24. but anyway what I'm hearing is high quality music, basically the song as I've always known it however better with more detail and more transparency and a better sense that you can feel the space of the recording. which when we're doing what it is that we do as high-fi enthusiasts is exactly what a lot of people are after myself included, basically the idea of hearing a familiar recording and having it move you in a new way. however when I listen to the same song on tidal which is available in MQA by the way, I can't help but get the feeling that what I'm hearing isnt necessarily the same as the high res version but what I'm hearing more is the same basic recording but presented in a new way.
while those two examples might seem similar or in fact the same thing, in my opinion I don't think they are, at least not the way I'm hearing it. think of it like a a painting now imagine that painting is hanging in your living room which is lowly lit by light.quboz Hi Rez to me is like adding a couple extra lamps pointed directly at the painting, you can see more detail you can see the colors more vividly and you get an overall better sense of what the artist intended. now with tidal imagine the painting is being seen with added lights but they're colored, you don't really see any more extra detail or color or anything that wasn't already there but you're seeing the same dimly lit painting in a slightly different way. I don't know I guess if that makes sense.
like I said at the beginning for me and my money quboz simply sounds better, sounds more natural and has better tonal qualities that I enjoy in music and as a lot of people comment on here it shows me more of the music that I want to listen to and that I enjoy listening to.
