Amp for Sonus Faber GP?

I own a pair of Sonus Faber Concerto Grand Piano.
I am looking for amp in the $2000-$2500 USD price range.
I've narrowed it down to 5 integrated amplifiers to drive my SF GP:
- YBA DT Integre
- Krell 300i
- Synthenis Simus
- Jadis Orchestra reference
- Manley Stingray

Which one is the best choice for my SF GP speakers?
If anyone has heard these or had the chance to compare them.
I'd be interested to hear your opinions.
Any other suggestions for other models are welcome too.

I mostly listen to classical music(Female vocals, violin&cello and piano).

Thanks for your kind help.
