Need a setup for work - Cans/DAC/Amp

hey!

welcome the the right place :)

my very first suggestion for you is to take a few thoughts towards the quality of  the music you're playing on your headphones. 192 is bad enough but 160 is.. it is a sin. ESPECIALLY if you're planning on getting your hand on the d7000's. The difference between 192/320/FLAC is quite significant already, and better headphones will bring out the worst out of strongly compressed mp3.

next.

are you working very close next to another person? I have a friend who's got the HD595's and as long as he keeps the volume down, it's not intrusive at all. Well, to my taste at least.. I can see how it could get on someone's nerves though. And since you've mentioned the whole thing, I assume you've already tried bringing your Senn's in and trying their openness on your colleges? :) Have they complained a lot? BTW the senn's sound pretty well unamped, but they totally open up when amped, though. But if you'd bring all that to work.. I can imagine the angry colleges after you crank the volume up. Anyways, it's very nice to hear that you're going towards the right direction!

so yea.. not sure if I was helpful at all, but the strongest point would be to consider acquiring some higher quality music to listen to, if you're planning to upgrade your rig. Garbage in, garbage out, as they say.

And you do not really want to amplify the garbage now, do you?

Mr. Enig is right on point.

Don't even think of moving up to the Denons if you are playing spotify or streaming stuff from the web without improving the signal chain first.  Yes a dac could help a bit compared to most dacs in the computer but then again most $200 or so beginner dacs are a waste of time at least for the caliber of headphone you plan to acquire.

Pandora and Rhapsody are okay and Spotify can sound good when you happen to stumble upon a track that is encoded at a higher bit rate, but many on spotify are not and it sounds like it.  No wonder audio geeks in the know and ones with some cash are using MOG.

If I were you and I wanted to get the best bang for the buck I would get a JDS labs cmoy with an external power supply and a Ross Martin dac which is exactly what I use at my desktop for listening to the stuff you plan to use, Spotify, Pandora, and my Logitech Touch which is streamed lossless files form my music server.

I have heard lots of dac amp combos like the Centrance Dacport, Nuforce, Little Dot and the above combo sounds better than most.

I'm just going to throw in my 2 cents here, as a beginning audiophile like yourself.

move away from built-in sound card and amp. Once your gone from that, you'll notice little to no difference in amps and dacs. I have dt 990s and hd650s they sound worlds apart(relatively anyways). However when I compare fiio d5 vs little dot mk III + asus xonar d2x the difference is far from as big as with the headphones(I mean very far) that's if the difference isn't a placebo. I'd suggest investing in headphones rather than sources.

Edit: also 320kbps does sound a bit better than 128kpbs, but don't think flac will be better than 320kbps,

I've heard good things about the nuforce udac2.  It is a dac/amp combo in a pretty small package.  It also can be used as just a dac if you wanted to try out different amps.  And it gets it's power from the usb, so no need for an extra power cable.  I don't own it myself but I'm considering getting one for work.  Currently just plugged straight into the macbook and with the Senn RS130 can't really notice a difference (the rs130 seems to lack some extension but it works well enough for me).

As for the source quality.  You're best bet is to try different encodings yourself with music you know.  Also don't just pick one song, try choose a variety of tracks in your library.  For me, 192kb is the high quality minimum for me, meaning I can sometimes hear differences between 160kb and 192kb but can't discern any difference above 192kb.  Depending on how noisy your work environment is that could be lower.  192kb is the safe level... for me... with my equipment.  Everyone is different.  For test tracks keep in mind that usually the first thing to go with lower quality are the highs.  So something with a lot of drums and percussion would be a good one.  With the size of drives now there's no reason not to rip all your cd's as FLAC and toss them on an external usb drive (assuming all you own is a laptop which may not have a whole lot of built in space).  That way you can setup a batch job to convert your flac to whatever quality works for you now.  Then when you want a higher quality or a different codec comes out you can setup a new batch job and let it run overnight.

*edit

Also forgot to mention if you aren't sure how open the sennheisers are then just take them in, play them at whatever your ideal volume is, and ask if anyone around you can hear it.  A coworker has the HD598 and you can't really hear them at the volume he plays them.  I have the RS130 which is open and that doesn't leak sound unless you are so close you're in my personal space :)  Although if your trying to drown out the people around you then probably you'll have to play them at a higher volume.  We had a coworker a few years back with HD600's i think... MY WORD did those leak sound.  I had my RS130 back then and with them on, playing music, and him maybe 10 or so feet away I could still clearly hear what he was playing.  I never actually tried them so I don't know if they are just really leaky headphones or he was killing his hearing.

Depends on the amp and the dac....and experience....it sounds awfully condescending and elitist thing to say I know, but the truth is if you're just starting out then you likely won't know what to listen out for nor are you half as likely to give things time to settle....also the headphone amps and dacs do have their own characteristic hues that they impart on the overall sound of the headphones as some are transparent and warm, others are punchy and bright. This is where the realm of synergy comes in to play....

At that price point, you have lots of good options within Audio-GD's lineup as well. Starting with the Fun, and moving up from there. 

+1 on Thommohawk's comments.  Not to pile on here but as things get better you are apt to hear more subtle differences in equipment, software, and files.  Flac is a lossless format and will sound better than a 320k MP3.  Whether you hear it or not will be dependent on your listening education, your equipment, and your ears. And  whether you perceive it to be a big or big enough difference is all about you.
