The quality of sound of an integrated amp?

I have a question which I am aware is likely naive, but I sincerely hope to gain some guidance from experienced audiophiles. I recently purchased a Jolida JD 100 CDP and a set of Spendor S5e speakers, leaving older electronics, a C-J PV-12 preamp and an Aragon 4004 MkII amp. I have been intrigued by information here about the new generation of high-end integrated amps, particularly the Portal Panache. Will I be advancing the sound reproduction of my system by changing to this amp? I listen to quite a variety of music, from old rock and pop, to folk, and to small ensemble and symphonic classical music. I have certainly already improved the balance and bass reproduction of my system, with good resolving capacity. My goal would be to improve further the emotional involvement with the music, which I'm hoping this (hopefully last for an extended time) upgrade could provide.

Thanks for your comments.
