I am now the owner of the Sony MDR V6 studio monitor headphones. Purchased based on the abundance of excellent praise and 5 star reviews on amazon.co.uk. I was looking forward to using them on my Casio AP420 digital piano and primarily on my Cambridge Audio Azur 640 seperate hifi system, listening mainly (okay all the time) to Dave Matthews/Band. Unfortunately for me, i find them to be more like the very small handful of 2 and 3 star reviews on amazon - full of this sibilence thing. Listening to DMB's new tracks, most them, in particular "Mercy", the sibilence is astonishing. For seventy quid I'm afraid they're on their way back to amazon. So the question is, what should I get instead? This is what i don't want....sibilience. no sibilence at all. And i do want good accurate, punchy/pacey bass. excellent everywhere else. wide soundstage etc. obvioulsy im not expecting everything, seeing that my budget remains the same (£70-£80 / $100-$120) mark. Music i listen to includes 99% of the time Dave Matthews Band (live recordings), but also Ben Folds/Five, Phish, and other jazz/rock/blues stuff. I've been researching Shure SRH550DJ, the various Sennheiser's and AKG. I just cant decide, and now i've found myself caught out by a product that 95% of people love, I've lost my confidence that judging by good reviews on the whole is enough to make a satisfactory choice. Or.....after enough use, do things settle down with the Sony's??? Will the sibilence subside? To be honest, I like them otherwise. Albeit, even on the digital piano (a very good one by the way, much praised in the sub £1000 digital piano world) i hear a faint "sizzle" after each note in the right ear. Maybe....the headphones are so good that they're revelaing something in the piano samples that i've not heard before. or they are indeed broken in some way. Thanks for any help in advance.
