Amp/Int Amp for SF Auditor Spkrs

I have just purchased a pair of Sonus Faber Auditor Spkrs with stands to replace my Vandersteen 2Ce speakers. I had auditioned the Auditors at length about a year ago, with my integrated amp (Marantz PM84). I am considering upgrading the electronics. I would like advice from fellow Audiogoners who are familiar with SF Auditor speakers on the pre-amp/amp combination or Int Amp that might work well with the SF Auditors. My budget is $2-3k. I listen to all kinds of music, classical (mostly), rock, jazz and Indian classical, all at moderate volume.
I have read good things about Lavardin IS and Creek int amps, as well as Sam Tellig's ravings about anything made by Pathos. While there are Creek and Pathos dealers where I loive (Chicago), there aren't any Lavardin dealers. Also Lavardin is rated at 30w, not sure if this is enough for the listening space (23 ft long, 11 ft wide and 9 ft tall, with 5ft doorways on both the long walls. The speakers will be located roughly 8 ft away from the back wall (about 13ft from listening area)and 1.5 ft away from the side walls.

Thanks.
