Hi guys , my 2 year old 32 ohm/106 db philips closed headphone is dying ,now am looking for open headphones. but im confused whether i need a dac because my source is a dell laptop (15r turbo) using conexant audio codec.
When i asked dell support about on board sound card they replied me that it gives output at 31 mW per channel into 32 ohms. The output voltage is 1 Vrms. with an integrated headphone limiter.( the link is given below ).. note that when i use my 32 ohm headphone there is no volume left to increase in my laptop & at full volume its not louder & its crap.So can i use 50 ohm headphones with 32 ohm source.
I am looking at Sennheiser HD 518 & HD 558 with 108 db and 112 db sensitivity.Among these which is best for my source. i dont know whether i should i stick with 32 ohm headphones like HD 449 .which i am considering in to...I am interested in HD 558 since it has more sensitivity, What would you guys recommend ? Can i go for it or should i stick with 32 ohm headphones ?

(Hope its not a bad source.........................)
