I don't have any amp or dac right now, as I am using my M50 mostly with my J3. When i use the M50 with my laptop, I just use the headphone out.
I know ATH-M50 doesn't need an amp and all, but since my future upgrade would most likely be HD650, I'm trying to buy a DAC and an amp. I can't buy everything all at once, and there is no need to, so I am thinking about buying one by one. My most logical step is DAC, amp, then the HD650, since DAC and amp can be used with my current headphone as well.
And with M50 being so easily driven, I wanted to know if I'd be able to clearly hear the difference when using the good old HO of my laptop and when using a DAC. Moreover, I would also like to know if the driving strength of an amp (basically any sonic difference between using a weak amp like e7 or a stronger amp like the m-stage) can also be noticed with my M50...
Do any of you guys have experience in this?
