Head-Fi Newbie

Recently I have a renewed interest in really upping my musical listening experience and have jumped in deep.  Got my Etymotic hf3's in my ears right now following 100 hours of burn-in (33 white, 33 pink, 33 brown) and another 100 of mixed music from my library  and they sound way way better then before burn-in.  I know many think Ety's are bass weak but honestly they really strengthen up after the burn-in and I have no problems at all with the bass I am getting.  As well I have no question in my mind that burn-in improves the sound of headphones; atleast Ety's, it is obvious it does.  

The stock ear pieces are a decent fit but I figured might as well go balls out and next week I have an appointment to have my custom ear inserts molded. To improve the source I have an XM6 amp on the way, planning to velcro it to my ipod touch (mixed lossless and iMatched everything) when I am out and about or as usb DAC replacement form my laptop output when I am home.  I am counting on the XM6 to give me the power and performance to match whatever I plug into it.  I am hoping it is able to sidetrack my macbook analog out and use the USB DAC but it is not clear to me if this will work and is compatible with a macbook and a ipod Touch for taking advantage of the USB DAC.  Anyone know for sure?  What is my best configuration for hooking the XM6 to my macbook and ipod touch?

Ok so that covers the ultra-portable side of the equation.  On the semi-portable side I have just ordered a pair of BeyerDynamic T5p's for also taking around when quality is paramount and for just chilling at home with a little more comfort then the Ety's can provide.  I envision the T5p as my goto headphones for both in home and out.  However, by coincidence of timing I also ordered a pair of Sennheiser HD-280 PRO's for when I want good comfort but don't want to risk the T5p, you know a bit more weekend warrior type use and for a difference in perspective from the T5p.  

These 2 wired guys will compliment my existing wireless Nokia headset which up until now has been my goto headphones other then the pair of Apple in-ear that I stopped using after getting the Nokia.  Sometimes I prefer wireless and the Nokia will remain for that purpose but I could be convinced someday to upgrade that to something better. Sennheiser I noticed makes a nice wireless headset with noise cancellation.  Any thoughts on this? 

Now that I got in ear and on ear covered I am also in the process of upgrading my desktop speaker system from Bose Companion 3 Series 2 that I have had for 2 years to a new Bose Companion 5 setup.  That will get used when I am feeling musically lazy at home infront of the computer.

So I guess the question is what comes next for me?  I am excited to be surrounding myself with awesome sound, something I never practiced an appreciation for until just recently after realizing why not.  Thoughts? 

haha, this is great!  thanks everyone.  yeah i am into traditional wetshaving too because at first i thought it would be cheaper.  20k later and i still don't have the perfect straight razor ;)  well i guess that actually is my point through all of this.  music surrounds me in life and why not just go for broke and make it the best it can be.  it is good to have a focus and the stax and amp are now in focus as soon as i can manage it.  i guess taking a couple baby steps first has to be done to say you been there, done that but that is my destination. imagine how many people go through life and die and have never had the chance to hear what perfection sounds like.  I am lucky enough to be in a position where I can manage it.

@cel4145 - thanks for the excellent advice regarding desktop systems... i am now seriously interested in the Philips SoundSphere AirPlay instead of the Bose but waiting to see if they introduce a new model inline with the upcoming new iPhone smaller dock connector.  the other option looks like the B&W MM-1's but I would rather have wireless I think for the asthetics and to keep the desktop clean.  The SoundSpheres are sharp and they look like they have great build and sound from the reviews I have read.

I have cancelled my Sennheiser HD-280 order and replaced it with a new pair of Philip L1's instead for the more casual around town sounds when the T5p is too scared to leave the house. Looks like Philips is doing some good work this year.
