Imagini ilustrative: DAC in stare tehnica/optica impecabila, fara absolut nicio urma pe exterior. Neumblat, nereparat, folosit sporadic si inlocuit in urma unui upgrade. Cutie completa, ofer proba pentru cumparatorii seriosi (am timpul limitat deci va rog fara pierdere de vreme).
Consider că punctul său forte sunt cele două chip-uri (AK4497) și dacă nu sunteți fani, mentionez cat se poate de clar ca NU doresc discutii interminabile despre AKM vs ESS.
Având în vedere că nu pot oferi garanție, prefer predare personală în București.
