Bullitt731 hi,
This is the only impedance graph I could find, and yes it does look to be tube friendly for good push pull tubes with low output impedance.
But this graph needs to be read in conjuction with a phase angle graph as well, and there are none of these around.
If the phase angle dips to -30 or more degrees at the 3ohm to 4ohm impedance between 50hz and 700hz, which some of the later floor standing 8 series do, then this can then look to the amp as a 2ohm or even lower impedance.
And a tube, even good powerfull one may sound a bit light on in the lower mids and upper and lower bass, and therefore maybe sound too lean and bright overall.
So unless you can find a phase graph, I would stay clear of tubes and even wimpy solid state.
