I think you should forget the L3000. The phone is not really worth at its price
I owned the L3000 and ATH-W5000 at the same time in the past.And I can tell you that if I want to buy audio technica headphone again, I will only buy the ATH-W5000
why? ATH-W5000 sounds almost the same as the L3000, but it has larger soundstage and detailer. The only thing that L3000 win (not a really huge gap, L3000 : 9 then W5000: is the sweet midrange. However, you will suffer high pitch of singer's voice if you hear at loud volume (the phone only becomes special at loud volume)
