Well done with the speakers. I hope he's shipping in the original boxes.
According to Stereophile, these speakers are tube friendly. Even though their sensitivity measurements were only
84.5dB/2.83V/m, impedance only dropped to about 6 ohms in the lower mids and much higher in bass frequencies. So, it's an easy to drive speaker.
You should have no trouble finding a tube amp to pair with the Josephs.
