I am building a Tubelab SSE and looking to the next project which will be a set of speakers. The 1Pi seems to fit the bill however after looking at the impedance graph I am unsure what to choose for output transformers. My initial plan was to go with a pair of Edcor GXSE15-8-5k. However the 1Pi spends a good portion of it's range under 8 ohm dipping down to what looks like 4 ohm at 2 points. Will the 8 ohm transformers drive them ok or should I be looking at a lower output impedance?
