No, I'm just comparing a heavily designed amp that was MADE to drive hideous amounts of current into a 1 ohm loading presented by your average Apogee ribbon speaker to a transformer coupled? valve amp with inevitable high output impedance and a corresponding shortage of damping (or very low frequency performance) into such cruel loads as the Sara's present.
If you really want to hear what a decent valve amp can do, ffs give 'em highly efficient high impedance loads (like vintage Tannoys for example). You'll restore some damping and the high efficiency won't challenge the amp's output like a Sara did and does
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
