Amp upgrade: Jadis JP15 + JA15 combo


I am currently considering an amp upgrade. Two questions: (i) Do I really gain much with switching from integrated to mono power/pre? and (ii) how does Jadis JP15+JA15 combo sound? Thank you in advance for any replies.

Current system:
Amp: Jadis Orchestra
Speakers: Peak Consult Incognito
CDP: Vincent CD-S6

Dear Pierre,

I am based in Europe but have heard numerous good things in different forums about your practice in North America. I do not have the opportunity to audition wide range of Jadis products and I would appreciate if you could let me know which Jadis product you think is a natural upgrade to Jadis Orchestra. My budget is around €6,000. Thank you.
Let me assure you that his(Pierre Gabriel) service is as good as it gets. I have called him of duty hours & he has replied to me ASAP even on weekends & public holidays. You cant go wrong with Jadis or Pierre Gabriel. Mind you I have used most of the hi-end stuff but keep coming back Jadis.
