1st: MQA is a very nice marketing stunt: It throws in high numbers of sampling rate to suggest that it's high quality, but it is a compressed format. Ask yourself: Do you want a new, closed compressed format with questionable benefits?
And then, if you look for reviews comparing Tidal's streaming, especially the MQA one, to Qobus' streaming, then you wonder if MQA is the horse you want to bet on!
Besides, buy the DAC which sounds for your music best!
2nd:
Never buy something blindly (unheard)! Left and right to your brain are your ears, and livelihood is high that you perceive sound different that me and the reviewer, and even if we perceive it the same, there is no chance that we also like the same type of sound! For sure, we can agree on the same grape for wine, but never for the same "type" of women, wine, clothing style AND sound! You get the point!
Last, I want to repeat the point already adviced, but this is the toughest:
Don't rush your purchase, you are robbing yourself an option to choose! Your headphones are new now, get experience with them first! Your brain is quick with it, but your unconsciousness not, and here is in my experience the difference between short term "sounds great" and longterm "I have to switch it off because it's getting ony nerves!"
Again, hear with your own ears, the interwebs are full of people's bad advice -- and you need your own experience to know what could be a route to try out or what is just one guy's (paid) bad advice.
Last: You said you like tunes. That's perfect with me. Do you know that there are solid state amps which sound like good tube amps? Look for no or little negative feedback, just 1 or 2 amplification steps and single ended (in contrast to push pull) design! Just for fun, visit a dealer with your headphones , and ask for the Pass Labs headphone amp to listen to.
Have fun on your journey!
