Hey all,
 
I have been researching the DT770(80 ohm).  How does that compare sound wise to the 25-1-II and the ATH-M50?   
 
I heard that these are preferably driven by an amp.  Do they sound bad coming off a desktop on-board sound card?  If so, I do have the desktop tied into an older Yamaha 290 watt amplifier with the following rating on the headphone jack:  [size=small]Headphones Jack Rated Output/Impedance  [/size][size=small]8 ohms, 1 kHz, 0.01% THD[/size] [size=small]0.6 V390 ohms.  Would that drive the headphones better?  I can buy an inexpensive sound card with headphone amp if need be.[/size]
 
[size=small]How about through smartphones?  Do they sound terrible without an amp?[/size]
 
[size=small]I may wait to see how the Custom Ones compare to the DT770.  They only require 16 ohms.[/size]
