Unison is good choice as is Pathos Classic II (am I getting name right=it's their 100 watt Hybrid.Second version supposedly sounded much better than firstb though fisrt one can be gotten much cheaper).There is the all tube Jolida 100 watt.I thionk you'd alkso be very happy with one of my amps the EL34 based EAR 834 integrated.40 watts push pull should be plenty since it does not sound like you want to blow the walls down anyway.Bel Canto would be great but is I believe out of your price range.Minimax is a company to l;ook up.See reviews of it at www.6moons.com.With Holida and Minimax you can swing both ame brand amp and CD if not new than on used here on agon.
