Hello Dmitre,
I have a Metrum Acoustic Octave DAC for sale. My unit was shipped to me 10/03/2012...it is in excellent condition & sounds wonderful. My unit will not play 192Khz files...it maxes out at 176Khz, sorry. Also have a Musical Fidelity V-Link 192 & 1m Locus Design Polestar USB cable for sale. If you just want the DAC ...$500+shipping. If you want everything ...$800+shipping. Have a great day buddy!
