P12,600 for the C315BEE in early 2008? Was that srp or after a particular dealer's discount? If srp (so that we can correctly compare it with P14K in late 2008 and P15K now), that looks like a 19% increase in about a year. Is this level of inflation typical in hifi equipment? Did the manufacturers cite any reason for their increases? Or do they just announce price increases without giving any particular reason.
I suppose we could expect another 19% in a year, so that the srp would be P17,850 in 2010, and likewise for other NAD and PSB products?
