  1. There is no DAC chip. PWM signal is converted by the loudspeaker since speaker is a capacitance-resistive load and effectively is a DAC for the pulse-frequency modulated signal.
  2. Yes, it is possible see Pulse-Frequency Modulation (Audio amplification down at he end). A new class of audio amplifiers based on the PWM principle is becoming popular. Called class-D amplifiers, they produce a PWM equivalent of the analog input signal which is fed to the loudspeaker via a suitable filter network to block the carrier and recover the original audio.
  3. I own one and I don't like it. My main system is Auralic Vega -> Senn HDVA-600 amp -> HD800, all balanced. Office is Teac HA-P50 + VMode. I also own Oppo portable DAC, Shure SE846, Fostex TH-600 and Oppo PM-3. Gave iDSD to a friend to try with HD650, he didn't like the unit either, said FiiO was much better. My daughter used iDSD for some time with iMac + Senn HD600, said no. So there.
  4. My bet is on Vega simply because company is founded based on their expertise and proprietary developments in digital hardware and associated software. Mac is traditional company, great analog gear but they never really shine in the digital domain. Disclaimer: I own Vega (used with Sennheiser HDA 600 amp and HD800 headphones in balanced mode)
