What need a CDP and an integrated amp to go with my Graham LS-9 speakers


15K budget for both. They can be new or used

I would love to hear the Rega Osiris/Isis combo. I own the next step down Rega pair Elicit-R / Saturn-R and I love them. I find them to be good value at their MSRP and a steal at their used prices. 

The Osiris/Isis combo is just a bit above your budget new MSRP, but perhaps a dealer would discount to your budget if you bought both at the same time. Used, it is well within your budget.
Have you considered just getting a very good DAC and something like the blue sound vault 2. I think In the long run that’s a better why for your dollar spent. Disc Spinners are dead when vinyl is out selling cd’s time to ditch the cd transports and CD players 
I've heard the graham Ls 5/9 with bryston, avm, octave 70se, sim audio & a bit more i can't recollect.
All were decent with the spk showing the flavours in the chain.
My pref was for the octave & the sim. 
You'll have to find the flavour that floats your boat.
All the best
Cheers
