Impedance matching and damping factors might be issues to consider.
Years ago I was running 90 dB/w/m, 8 ohm, 30-20,000 Hz AlNiCo single driver speakers in a 12 ft x 19 ft x 8 ft room with a 7 wpc T-amp. Results were perfectly acceptable, but moving up to 40 watt mono-blocks turned the speakers from polite dinner guests into NFL linebackers in tuxedos capable of hard hitting and greater control (improved imaging/detail). Current Omega offerings would have roughly the same efficiency to dB of gain ratio (reaching about 96 dB at one meter). Of course realize that 96 dB is really loud (continuous) but symphonic peaks are 105 dB and rock concerts average 110 dB, so these are best suited for late night/small ensembles.
Most Omega speakers, with F3 around 50 Hz, should benefit from low damping factor (typical of tube amps) to boost bass output. On my same speakers I auditioned a 6 wpc Decware SE34I (version 1). More powerful than the T-amp and can you say palpable? But with those speakers it made lots of flabby bass.
BTW Chord is supposed to be releasing two home versions of the Hugo in April, a cheaper one (2Qute - $1800, no volume control) and a more serious one (Hugo TT - $4800). TedB, Audio Circle member, is supposed to be working on a review for Computer Audiophile.
