I am thinking of getting one of these three DAPs.  How good is the X5 gen 1 versus the X1 and the X3 gen 2 sound wise?  I will be using the DAP with mainly Etymotic HF5s, but I also have Grados and Sennheiser Hd-600.  I also have a Ray Samuels Emmeline XP7 amp to use with the headphones.

Did anyone notice that on the Grado Labs website it was updated to say that the street styles will be shipping on Sept 1st? I can't wait to buy a pair.

Like I said in my title I am looking for the part number for the headband part number and the price of it. I bought a pair of HD580 and I tried to wash the headband pad and the foam in it flattened out. Also one more thing, what is the number I call to order a new one here in the U.S.

I just saw this on ebay and wanted to know some information on it. How many of these were made and is it really being sold by Tyll's brother? http://cgi.ebay.com/VINTAGE-BLUE-HEA...QQcmdZViewItem

I am in the market for a headphone amp. The headphones I would be using with it are HD600 and SR325. The amp needs to be something I can use at home and be portable that I can take to work to use on my breaks. I was thinking something up to $400 new or used. Cheaper the better.

I am thinking about buying a pair of either HD580 or HD600. The HD580 are $158.07 and the HD600 are $199.99. The HD580 are factory refurbished and I think the HD600 are also. My question is, should I save the forty bucks and get the HD580 or spend the extra money on the HD600? Thank you in advance.
