I sat at a friends house and he played several songs, from both Tidal and Quboz. Each time, I selected Quboz as the preference I had. Basically, he was comparing MQA vs Quboz and he wanted to see if I could pick the same service. Well, my 59 year old ears could. Hell, I hear a difference by using cable lifters in my 2-channel system.
Now, I have said many times… if what I’m hearing is a psychoacoustic or placebo, or whatever… I really don’t care! It’s my money and I’ll spend it how I feel appropriate.
There is a technical difference between Qobuz FLAC and MQA from Tidal and it might be that it was a difference that you picked up. If it was a blind test that was probably very good perception on your part, if you knew what you were listening to you may have been influenced by that. That isn't a criticism it is just a statement of fact.
It could possibly even be that the same master was not being used by each service, not implying that would have to be the case but it is a possibility worth mentioning.
If you can hear a difference with cable lifters in a comparison where you don't know which situation you were listening to and did that often enough to be statistically meaningful (like at least 8/10 or better 18/20) then that is a very solid data point for you such that it would be worth deeper assessment because logically that is rather exceptional. If it was a sighted comparison you were open to psychological influence, there is simply no arguing that, it is a statement of fact not an opinion.
You are more than welcome to spend money based on effects that are psychological only, I do that with nice cables also, they make my listening experience more enjoyable because they give me some pride of ownership, nothing more.
We are all wired differently and if you are happy buying, for example, a new amplifier and enjoy a new sound despite that you acknowledge it might be only in your imagination that is fine by me, no argument at all.
I don't want to do that, I prefer to understand what is actually making a technical real difference as best I reasonably can, and that is as valid a position as yours. If I want to base buying decisions on technical understanding rather than feel good factors I don't see any reason for anybody to object to that.
