Red Wine Audio Isabellina (Audeze Edition)-WTF is this crap? Imagine a syrupy and smeared Leben being run through another broken Leben as a preamp.
Antelope Audio Rubicon- 'Con' being the operative word. Think Benchmark DAC-1 but waaaaay more expensive ($25,000 Euros). Only listenable via upsampling. I'd say the price is worse than the sound. The ODAC and Geek Out get you closer to the actual music on your recording.
Ultrasone velour pads (Pro 750)-If you ever wanted to know what earpads made of fiberglass insulation would feel like.
AKG K812-The most deafening treble I've ever heard in any headphone. Not remotely close to HD800 technicalities even if it wasn't. Listening below 30dB recommended. Perhaps using 'Mute' would work too.
Magnepans+Bryston-The acoustic version of braille. You're better off using your car stereo.
Already mentioned:Mytek/Teac-distinction without a difference in treble
JHA 16/Roxanne-Bass!!/Why? WTH is this sound about?
Shure 1440/1840-Distortion monsters without peer
Oppo PM1 (original)-If live music sounds like this, then the orchestra is playing with AM/FM radios.
Leben-Can go from 15W-40 to 10W-30 if that's your thing.
Meridian Exploder-Hah! How stupid do you think we are?
Denon D7100 (original)-Beats meets You've been Punk'd
