I really couldn't believe my ears for these. I let them burn in for 30 hours as Kevin at Superlux has informed me and put them on. "Wow, these cost how much?" Was my initial reaction. The sound is fantastically balanced with amazing clarity and a natural sound, that rivals my Ad900. While these are labeled as Studio Monitors don't let that fool you, I'm having a lot of pleasure listening to these, they aren't as music as my Ad900, but are more musical than my Ad700 and HD558. The bass extends well and has a nice full warm sound, it does lack impact though for electronic music such as drum and bass. The lows do leak a little into the mids a bit, but only so slightly as to make them sound a smudge recessed. The mids are full sounding with excellent clarity. They don't have the forwardness my Ad900 have, but they do a wonderful job for rock music regardless. The highs are a little tame, but they extend well. By tame I mean that they aren't piercing or overly bright. They still extend well with excellent clarity. The soundstage is great, it's not as big as my Ad900 or Ad700, but it definitely gives the music some room to breathe. Time to listen to some tunes!
