Right now I'm using an HD650 with my Little Dot Mk IV SE amplifier. I'm wondering if I could get some opinions on good 'phones for upgrading. I'm mainly a classical music listener. I like a warm midrange. I'd like to keep it around $1000 or less. I know that the Hifiman HE500 is one possibility. I doubt the HE6 would work (probably needs more power than I have). The Audeze LCD-2 is one possibility. What other 'phones are in the < $1000 category that you might think sound good on classical music with the Little Dot? Midrange is my highest priority, followed by treble extension.
