I use a Wadia 151PowerDac mini to drive my Stradas in a 9x10 room. It plays more than loud enough for me, but the hard core rockers might not be satisfied. The Wadia punches above its 25W RMS power rating.
I can't comment on the Virtue Audio amps, but if all you need is one analog input, the little guys might work. If not, they have the Sensation amps.
