Lovely, well done.
Be mindful that with the Miflex copper caps, they will need about 425 hours of burn-in to sound their best.
With respect to something to drive them, and keeping with the DIY theme, I drive mine with a pair of Nelson Pass "Amp Camp" Class-A amps I built up at the same time, running as bridged monoblocks. Cost: $654 for both, from the store at DIYAudio.
