Old Philips CD as transport or new playe

I need help with an upgrade. I have a 10 year old Philips CD-50 CD player, which happens to have a digital out. I see my options as:
1. Use the Philips as a transport and buy a reasonable (e.g, MSB or Perpetual) DAC; or
2. Toss the Philips and get a new player or transport-DAC combo.

Can I get some input on whether a 10 year old player (original retail about $300) will mate well with a new DAC or is it too old to be worthwhile and I should buy a new player/transport-DAC? Prefer to stay around $1,500.

BTW, the rest of my system is Plinius SA-100 Mk III amp, Rogue 99 pre-amp, into Coincident Super Eclipse speakers.

Thanks for the help!!
