Hi Guys , First of I would not call myself much of an audiophile but I'm quite picky on audio quality. Anyhow I would like to humbly get some advice on weather I should get Sennheiser Amperior HD 25-1 II or V-Moda Crossfade M100 or others. My portable DAP is COWON S9 with Fireye Mini amp and my computer has an external Creative sound blaster X-Fi HD sound card. Currently my favourite gear is the Audio Technica ATH-CKM500. So, basically I am looking at this two option as kind of an "upgrade" / different experience. btw I do like my music to sound "exciting" I used to own a Grado SR-60i and find them as OK for my kind of music. I did tried briefly on the AKG Tiesto K167 recently and find them not bad as well. My main type of Music would be (HOUSE) hence apart from BASS the mids and the highs are not to be ignored. Please feel free to suggest any other headphones if you may have any. Thank You Guys Mike.
