Integrated amp for Proac D2

My first post here.  I have some Proac D2s with the dome tweeter.  I use an old NAIM Nait XS that I bought used many years ago to drive the speakers.  I like the amp, but I am ready for something new.  I know the topic of different Proac speakers and amps has been visited many times, but I would appreciate your input on a good match for my speakers.  To start with, any thought on the new Cyrus integrated amps?  The Marantz Model 30?  I have a decent budget for the new amp - $2,5000 up to $5,000.  Lower end is better, at least that is what my wife thinks.  Thanks for your help.
