Aerial 9 isn't for tube amps in any room.
Aerial 9 isn't for small rooms either.
I have Aerial 10t(not tube friendly either) that are in 15'x20' with listening distance 6' and 6' appart. They're driven by 500Wpc of class D amps and I listen to them for a very long period of time equivalent to changing 7...8 vinyls in a row.
I also have Totem Forrest(will sell for dirt cheap) that are IMHO designed to be a perfect match to any tube amp >=40Wpc due to their stable 8Ohm impedance.
