Phew, pretty long thread, finished it at least ))
Thank you all for informative comments, they are very helpful.
I guess I've read every comment and review on the internet and watched every video on youtube about srh1540.
So, almost all my potential questions about them are pretty much covered
The ultimate question will be answered by my ears, in like a week or so.
Just one question left, I have atom amp+ & topping d10s combo. Has anyone here got experience with this duo paired with srh1540?
My logic is that they should pair well, because this amp/dac combo is pretty transparent and srh1540 is warm sounding headphone.
I also have fiio btr5 with 2.5mm balanced output, but I'm not sure I want to spend more on balanced cables and even then, I"m not sure btr5 will give me better sound on balanced than atom+topping.
Thank you guys one more time for this much information condensed in one thread, that was fantastic reading
