Ah, I see. Thank you for the speedy response. Much appreciated :)

If you want to speed up the process make a play list and put on repeat and walk away. You can also do this using pink noise... however using pink noise (Which I've never felt the need to do myself) should be done with 30min intervals every 2hrs.
As far as your dac/amp it could be a number of reasons for the static/low-rumblings, what you could try is open the dac and use a air compressor or air-in-a-can to dedust "do not use a vacuum cleaner" as this will create static. If you end up wanting to buy a new one specifically for the HD650's check out what dac's others use on the forum that use HD650.
Yes you can enhance your iTunes library by using "free source" application called Foobar2000 which most headfiers use on a regular basis, mainly because of a plugin called ASIO which gives you the ability to play your music in bit perfect to bypass windows altogether. If your hungry to learn you will want to know more about Foobar and ASIO...... That said, there is nothing wrong with listening to music through iTunes while you learn more and consider your options for more gear, if that's the road you take.
Lastly I'm also new to audiophile equipment, so hopefully I've given you the right information. Enjoy your new senns mate :)
Really appreciate the response! I think I'll take the more laid-back approach to burning-in and just play as much music as possible; though I do already thoroughly enjoy the sound so if they get even better that's just a bonus haha.
In regards to Foobar2000, it sounds very interesting and I'll have to give it a more in-depth look. That said, do you have any recommendations on places to look for said information? Any good articles/write-ups out there for someone like myself who has absolutely zero knowledge of how digital-audio "works". It's kind of funny because now I have even more questions and it's driving me crazy hah.

But I'll just say, it's way more likely that your hearing (which is a crude sense frankly and we are not dogs) and how a devices "changes" over time is more psychology of expectation and accustomization, then it is truly appreciable physical change. I say this because to keep it brief and simple, since burn in should be a physical change, should be able to be measured via a change in how it produces sound. Even if it's subtle. And the reality of this is that nothing conclusive or repeatable without massive loads of obvious bias has been produced to this day on this subject. My advise to you on this subject: just listen to your gear and enjoy some music. Don't get caught up in this silly ritual sorcery stuff. Use your own ears. You're not doing anything wrong enjoying them on day one.
2.) It's possible that it's just noisy from age, dust, old parts, corrosion, etc. If you want something clean in the $300 range, I would have you look at three options: A) The Schiit Modi/Magni, B) the JDS Labs O2 & ODAC, and C) any DAC with an entry OTL amp like the Little Dot MK II (and preferably try and find a used amp to keep costs down). Good match has everything to do with your preference, known as synergy of devices together. Put all your priority on the headphone, an amplifier that has output sufficient and appropriate for a high impedance headphone, and then a basic, but clean and simple DAC (this can be very inexpensive too, contrary to what you'll read honestly).
3.) If you want high quality music, you're going to be buying it. I would suggest you hunt Amazon and Half.com or even eBay for used CD deals and used collections. I get CD's for $3~5 all the time off Amazon used. I then rip them myself. Alternatively I also get music in high sample and high resolution from HDtracks.com, but you have to be picky about it and preview things (which is nice and everything has preview on that site); prices are fair there considering some of the quality. I would suggest you start listening to uncompressed/lossless via something other than iTunes, like FooBar2000, using FLAC or WAV or if you must compress, some MP3 at 320kbps using the Lame Codec. The HD650 is pretty forgiving of quality since it has a big treble roll off, so ultimately it will sound fine likely, even with compressed sources so long as they're not just completely awful.
First things first, a huge thank you for the thorough response! Very helpful
1) Luckily, I already find myself very happy with the sound of the HD650s so if they were to get even better, then that's just icing on the cake. I appreciate the info and words of wisdom though, very nice :)
2) The thing is admittedly pretty old(10ish years) though I am absolutely clueless as to the longevity of these kinds of things. In terms of an upgrade/replacement, I'm beginning to lean pretty strongly towards the Schiit combo. It has such a nice price-point, the reviews seem overwhelmingly positive, and I can always keep upgrade to something better down-the-line and have them as a more portable back-up( or convenient birthday gift haha). In terms of priority, I find that a bit surprising but maybe I'm just misunderstanding their functions. I get that the headphones come first but doesn't the DAC take all my music and "translate" it in higher quality? What exactly does an amp do besides allow me to listen to my music at a higher volume? On a semi-related note, something I noticed right away when I plugged in my 650s for the first time was that everything sounded quieter and that I needed to turn up the volume on the stereo receiver in order to better experience the music. Is that what people mean when they say certain headphones need certain amps in order to "drive" them? Are the HD 650s significantly more power-hungry than the 595s? So many questions, aaaah! Haha
3) As silly as this may sound, I just don't see buying CDs as an option at the moment. Every ounce of music that I own is on iTunes and it's super-convenient to have it all right there in one application while also being my primary way of discovering new artists. Although, I don't want to completely close the door on that option though and maybe further along I'll experiment with making the switch but, as for now, I think I'll be sticking with the digital side of things. In regards to listening to higher-quality formats, HD Tracks sound excellent but they don't exactly have the scale of selection as iTunes. For that matter, and just to get some more clarity on the whole process, why exactly does iTunes compress the music to a lower quality format? Would I be able to just convert my iTunes library to a higher quality format and listen to it there or is that non-sense? Finally, if I were to buy some CDs and pop them into my tower, could I play them in iTunes while preserving the CD-quality sound? Sorry for the overload of questions again but all this info just has my curiosity burning and I'm at a loss as to where to find more information on these topics. If you have any recommendations on articles or write-ups of these topics, I'd be very interested.
Once again, thanks so much for the responses guys. Very much appreciated and very interesting. Cheers! :)
