Devialet. Long term satisfaction?

Hello.

I am interested in Devialet integrated amps. Lots of great reviews, but would like to hear from actual owner experiences.

1)Did the Devialet perform well in your system.

2)Once the wow factor of how clean and detailed the amp sounded, did you get musical satisfaction.

3)Could you detail what components the Devialet replaced?

4)Anyone gone back to conventional amp after Devialet?

Thanks for any info
