Need advice on buying stereo system

Hi,

I'm looking to buy a stereo system (will be mainly used for music and NOT home theater\cinema).
These are some sets I have listened to, and I am interesting in your opinion regarding the companies & models (if you had any experience with it).
The first 2 sets are brand new while the last 2 are used (i.e. from second hand or display).

1st set:
Amp – Cambridge Audio Azur 840A Class XD
CDP – Cambridge Audio Azur 640C
Speakers – Focal-JMlab Chours 726S

2nd set:
Amp – Arcam A70
CDP – Arcam CD73
Speakers – B&W DM602 S3

3rd set:
Amp – YBA YA201
CDP – Audio Analogue Maestro (the model before the last one)
Speakers – MFSL OML-2

4th set:
Amp – Audio Analogue Verdi
CDP – Audio Analogue Rossini
Speakers – Audio Physics Yara

Any comment\suggestion\idea will be appreciated.

Thanks.
