BNIB SMSL 36a-pro Bought on impulse, but decided to use old AVR instead. Now selling brand new, except to test if it is working. Black color; comes with US 2-pin plug but adapter runs 100-240V AC, so SG no problem. Sound is crisp and clear. No audible distortion at 2 o'clock volume, already very loud. Meet up at my house void deck or Bishan MRT/Junction 8.
