Kung Sonus Faber, that would be Upscale Audio. Sadly, that shop closed down even before Park Square One was renovated. This is the same Upscale Audio found in MegaMall before, then they transferred to Park Square One, before closing down for good. They closed down during the time AMX was still in Park Square One, so matagal na yun. Mga 2010 pa yata yun.
