$1000 upgrade budget- cdp or speaker?


My current system is centered around much tube rolled c-j cav50 integrated tube amp (45w per ch) driving a pair of BW cdm1 se on the Osiris stands. The front end is a Toshiba SD9000 used as a cd player.

Although I have enjoyed the combination for the last 5 years, I am thinking about the upgrade path now. For a budget of $1000, I am considering either to replace the Toshiba with well reviewed CD or SACD combo(used Apollo, Cary 308T, CEC, Sony SCD777es and others) or sell my speaker and go get a used pair of BW 805s.

The listening room is not large and I do not push the volume too much in consideration for the neighbor downstairs.

Any opinion or suggestion would be welcomed.
Thanks!

NO BRAINER -B&W N805 - if you don't over drive it hard this is a great mini-monitor!!!
Thank you all for thought-full responses. I’ve enjoyed reading point of view of both side.

Some further questions…
Is the cdp the weakest link in the system as some of you have said? Is the current source,Toshiba sd9000 which is close or better as a cd player than very well reviewed sd9200 of 5 years of age really out of date that something like Oppo will out perform in my current system? I’ve also considered adding DAC instead of replacing the cdp, but ruled out in favor of keeping the system simple.
I'll put forth a contrarian answer, and say replacing the CJ CAV50 integrated amplifier will give you more improvement than either the CD player or the loudspeakers for your money.

My next move after that would probably be the CD player.
