I think for 15k you can only get a used Marantz CDP and the hifimart prices have got increased because of the fluctuating rupee. Even I am looking for a Marantz CDP in a good condition for <15k budget.
If you are ok with forum member pre-owned, post in the "Wanted" column. Would suggest looking at the "For Sale" column daily. You missed the Marantz CD6003 which sold just yesterday. Or was it you who got it!
