As far as I think, speakers are the most important component in your setup. Once done right, they do not need to be replaced for decades, if existing speakers in duty are taken as examples (that were engineered decades back and hence may be engineered better).
Next best component is pre/ power amp that can also last easily for 10-20 years.
So purchase decision for source can be pushed to the last. Not that they are the least important component - but it is not too much sense to design an audio system around a source.
Sources and formats are the most changing stuff - though it can be argued that vinyl is staging a comeback and CD format is 2 decades old already. But DAC/ oversampling/ loss less formats etc can confuse you a lot. Also, these days, dedicated comp for music duty can outperform a CDP by miles on quality, functionality and longevity of software (CDs/ vinyls may get scratched, but data files will not wear out by themselves)
There was an interesting thread on what hifi, where a user asked whether to settle for an amp first, or a speaker? And one of the practical advise was - settle on an amp first - so that you can carry it around easily to audition. Carrying your speakers around can be too troublesome. OTOH, with that kind of budget, I am sure you can summon a lot of dealers to bring equipment to your place. In that case, it would be easy for them to carry amps and sources.
So - settle for speakers first, and then ask dealers to come to your place to demo their source/ amp etc.
Like venkat, ,moser and soon myself joining them, you can try getting a comp for the source duty.
