Is it time to upgrade my amp?

Hi there!

I'm looking for some amplifier upgrade advice. My current system is:
Rega RP6 with Dynavector 10X5 MM (I intend to upgrade the cartridge to a Rega Ania Pro MC)
PS Audio NuWave Phono preamp (just received today and not added to my system yet)
Arcam FMJ A19 integrated amp
Audiolab 8200CD 
Monitor Audio Gold 100
I plan on adding a Cambridge Audio CXN (V2) soon.
Over all my system sounds great but a little harsh so I was considering upgrading to an integrated tube amp <$3k. I have considered, the Rogue Cronus Magnum 3, Sphinx V3 and used Cary SLI-80. None of which I can audition close to home.
Any advice on getting the most out of my system would be greatly appreciated!

Thanks! Chris
