Amps/Preamps for Rockport Aviors

Hi everyone, I just ordered new Rockport Avior speakers a couple of weeks ago and they are coming next week.  My current system is: ARC ref 75SE amp; ARC LS 17se pre amp; simaudio 280d dac and network streamer; Feikert turntable, ortofon cardenza bronze cartridge, and a boulder 1008 phone stage. 

I am thinking about upgrading my amp and preamp for the Aviors.  I was looking at the ARC ref 250SE as well as a used Boulder 2060.  For the preamp, not sure, maybe an ARC REF 6 or a used boulder.  Someone also suggested I look at a simaudio evolution 860 or 870.   My one concern with the ARC ref 250SE is whether those amps will pair well with the Rockports or if im better off getting a solid state.  I am not married to either tube or solid state (I had krell a long time ago before the 75SE and bought the 75SE becuase i thought it paired well with my Thiel 3.7's). 

I am brand new to the Avior speakers and looking to get more out of them than my 75se, and would greatly appreciate anyone's views. 

thank you in advance.  Larry

I've been driving my Aviors with the very rare and wonderful Pathos Inpol2 Integrated amp with NOS Mullard tubes used on the input stage and MOSFET on the output - 45W pure class A.  The only thing i've heard as good is the Vitus SIA-25, which is all solid state and 25 W pure class A.  It does a wonderful job at XXX times the cost of the Pathos.

I'm having a very special pushpull 300B integrated made by Berning and so will be selling my Pathos in the near future. If you are interested in this incredible integrated, to let me know.

Contrary to what some posters are saying, the Aviors are relatively easy to drive with a 90db sensitivity and nominally 4 ohm load.  They dip to 3.1 in one or two spots, but have generally smooth impedance curve. As i indicated, the 25w class A of solid state Vitus works beautifully as does my Pathos at 45w class A.  I also expect my new amp of 20-25w pure tube class A will be just fine.  Don't get sold a bill of goods on needing high power amps ($$) for the Aviors . . . . It's the quality, not the quantity! . . . .
