Speaker Choice for Almarro 318B

Guys, I'm a budding audiophile looking to jump up to tube amps after a few years with an Arcam/B&W integrated combo. I've become smitten with the Almarro 318B integrated tube amp and now I'm in the market for some affordable speakers that will suit the amp better than my B&W DM 602 S3 speakers. The room is approx 14'X 16', hardwood floors with a small area rug, celings are approx 10' high. Speakers will need to be placed close to the wall. I listen to an eclectic mix of music that veers from noise rock to experimental electro acoustic to HEAVY avant metal ala Sunn O))) to more traditional things like PJ Harvey and Radiohead. I'm in need of a good speaker recommendation. I've been looking into Green Mountain Audio Europas, Zu Tones, Gallo Ref 3.1s, and the Omega Super XRS speakers. Can anyone point me in the right direction here? If I had the cash I would get the GMA Callistos based on reputation, or the Zu Druids, but I don't think I even have the space for these speakers. I am leaning toward a used pair of Europas for $650 shipped. Should I take the plunge? Please help! I want a speaker that will be a noticeable step up from my current setup...Will the GMA Europas mix well with the Almarro 318B? Thanks!
