MH 751 or ATH MSR7?

Hello!
After trying many different sets of closed backs I think I’ve nailed down the two I’m deciding between in terms of closed backs under 200$ or less.
Headphones I’ve tried:
Koss Pro4s
Sivga 006
Takstar pro 82
All of which are generally sub 100 but I honestly can’t find much competition for these headphones above 100 yet under 200.

I used the 82s for a loong time until I finally abused them enough for the right channel to stop working (and yes It was not the cable). I like the 82s a lot but in pursuit of an upgrade there rlly isn’t much under 200$.

I want a pair that will scale with gear preferably.
I settled on the mh751s because they are basically the 82s, I am yet to find anything better than them in the price range and I already know how they sound and feel and I know I can’t go wrong.

I also am considering the ath msr7s as they seem maybe not a direct upgrade from the mh751s but from what I’ve heard they have a signature I like with increased highs and I am willing to spend more than double the mh751s for them because from what I’ve heard they are pretty good and I want to take a leep into a better set of closed backs than the mh751s.

I haven’t seen any reviews or articles saying whether the msr7s are worth buying or are even an upgrade from the mh751s, I guess because they technically are in their own price tier.

On a side note
Also any thoughts in comparison to the 006s?
Ive been using them temporarily until I figure out what I want to do and I honestly love them but I am a musician and record frequently and the 006s don’t rlly meet the neutral and accurate sound that I want when listening to recordings. I haven’t listened to the 82s In a while due to them being broken I can’t remember which has a better sound signature or at least which sound signature I like better.

I did use the koss Pro4s for recording but I sold them recently to buy a new set which is what I’m doing now. As the Pro4s were kind of lacking for casual music listening.

Basically what I’m asking: is it worth getting the msr7s over the 751s? Or just save the 100$?

I have mh751 I got em for 52 euros, they are super flat super soft comfy if you can get them for that price these days get em, it’s impossible to be disappointed unless you want bass, they are actually awesome with eq.

They’re currently full price on amazon rn so we’ll see, I mean if I could find a pair for that cheap I’ll probably end up getting them and the msr7s
