Extra Info: The CA-401 is balanced from input to output, resulting in a greatly enhanced signal to noise ratio, lower induced common-mode distortion, lower distortion overall, and freedom from grounding problems. The power supply of a CA-401 includes a massive, shielded toroidal transformer. For each channel we use a large collection of small power supply capacitors. Small capacitors "drain" and "refill" extremely rapidly and completely, supplying all the power required when the source demands it, with no bounce or overshoot. The fast, clean power supply allows us a higher degree of accurate voltage regulation at all stages of amplification. Thus no matter what program material is being played, at no matter what level, the voltages at all amplification stages remain completely stable. The oversized, fast, very high current power supply allows the amplifier to deliver the full current and voltage required to even the most difficult speaker load. The CA-401 delivers sound which is clean, liquid and effortless. Imaging, with the better recordings we all enjoy listening to, is both wide and deep. In fact, imaging seems real and human, without the artificial hard edges so common in lesser amplification. (taken from the Classe website at

      Item: MrSpeakers (Now Dan Clark Audio) Aeon Flow Open Backs
      Location: Sydney (Northern Beaches)
      Price: $600ish, although ill consider any offer
      Item Condition: Ex-Demo unit from Addicted to Audio, very limited (maybe 10 hrs absolute max) use by me. Very good condition, no visible wear.
      Reason for selling: Impulse bought these headphones on sale, and whilst i think they're great, as a student i can really afford to spend this much on headphones.
      Payment Method: Would rather pickup, and will happily offer a discount for that. Will take cash or bank transfer. Can post for a good offer.
      Extra Info: As i said above, i bought these as an ex-demo unit from Addicted to Audio, and have been assured (can provide proof) by customer service that they come with the full 2 year warranty (probably only a month or so used up). However since they do not supply any headphones from MrSpeakers/DCA anymore, they will not handle the warranty. Instead it will be handled directly by MrSpeakers/DCA, which may involve shipping to the US. Its not ideal, but better than no warranty, and i thought it would be best to disclose this.
      Edit: I have spoken to customer service at DCA to confirm this, and can forward on any information they gave me if you are interested.
      They come with 4 sets of tuning pads, as well as the case, and a microfiber cleaning cloth.
