Look at the AudioKinesis Jazz Module or Dream Maker, or the T5 speakers from Classic Audio Reproductions.
Basically, what you need is a speaker with a sensitivity of 89+dB (or higher depending on your room size and listening volume), and a flat impedance curve that does not dip below 8 ohms. That's the basic formula for a good speaker match with any tube amp, and one with relatively low power.
The speakers from Merlin, Acoustic Zen, Devore Audio, Zu Audio, and Coincident also meet these requirements to a large degree.
