Same cable as for the McIntosh MHP-1000 headphone or the Sony MDR-Z7. Price of the Elear is spot IMO. Anything else would devalues its performance. No comparison... LCD3 is the BMW M3, Utopia is the Lamborghini HURACÁN. A quick video on Elear
This is how I see it. If the song or concert is not available then a mediocre sounding file is better then nothing. The sound quality really depends on the DVD. Some sound as good as a commercial CD while some sounds like bootleg.
I think the Elear will hit the high-end hp market hard. Performance, build, design, comfort, and price will make it very difficult for others to compete. I'm buying one too with Nordost Heimdall2 upgrade cable when it's in stock.
