haha,i am happy now that i previously thought the dt880 is not a loud phone but i was wrong,in fact i just change the panasonic cd player to my cheap sony mp3 player,i cant believe how happy i am now as the headphone really feeling warm sounding and very detail when playing from the panasonic pcdp .i just cannot believe this cheap sony would match so well with the sr71a and not to mention i am using its main headphone out and switch it to it's highest volume,i read somewhere in forum that said the maximum volume actually or normally equal to the line out port.excuse me if i got it wrongly,but i am happy now to experience my headphone with just another music player that play mp3 so so so well,even surpassed the panasonic cd player which playing the purest cd contains via its line out.how could it happened?though it's just my opinion as of now,i wont know what i will like most later on haha...but still should turn down the volume a bit now as i don't want to apply any hearing aids in my age of 40's.
