For everyone complaining about the price being too high, consider that this isn't a mass-produced consumer grade product molded out of plastic and dumped into retail stores across the country. This is a niche passion-product built by a guy who clearly loves audio innovation and the fact that something like this, a beautiful, portable DAC/Amp that is compatible across multiple platforms and can be customized to fit several of the top selling smartphones even exists is incredible in itself. Based on aesthetics and functionality alone I would guess the price to be around $500. $700 with a custom Metallo case isn't unreasonable. Yes, it's pricey, but that's the nature of nice things.
A Sennheiser Orpheus goes for around $30,000, and the HD800 is $1500. Do you think there is a $28,500 sound difference between the two? How about between a Lamborghini and a Corvette? Is the $150,000 price difference really related to performance, or is there something else you're paying for? Italian design, guys. Sexy Italian design. I, for one, eagerly await the day my funds allow me membership into the VERZA club.
