Well, that is only one part of the equation, but it could be a big part. I've found that while the T50RP can sound decent on things even like smartphones alone, they noticeably scale with better gear (substituting T50RP for Mad Dog since this applies to almost any stock or modded T50RP). They even work well with power amps that are generally used for speakers, much like the HiFiMan line.
If you have a desktop computer, I've found some of the sound cards with good dedicated headphone amps to be a really good value. I got an Auzentech Bravura a couple years back for $90 refurbished. I did not hear any appreciable differences when I got my ODAC/O2, though the O2 had more headroom to play with. It worked pretty well with the T50RP.
But, really, I still stand by my opinion that you need to give yourself a lot of time with the T50RP. With both the stock, personally modded, Mad Dog, and Paradox, I found I always had to give myself time to adjust to them. I'm not quite sure what it was about them, because now I have no issues going back to them even if I've used other headphones for a while. *shrug*
You definitely got a 3.2. I just asked because some buy used without specifying right away, and I'd heard similar comments from those that got used 3.0 models.
