If interstage transformers are done right, they can sound better than resistor/capacitor coupling. Sun Audio does it right. Harvey(Dr Gizmo) Rosenberg was orgasmic over the Sun Audio kits.
I agree that if your speakers can go as deep as you need, the single 300b can do it. The single will not be as tight in bass dynamics as a SS amp, but the tone quality will be very good, and will likely be better with a single 300B.
I believe that Direct Reactance Drive is another name for choke-loading, and is a very good way to provide better linearity in the circuit. My 45 SET amp is using choke loading and I like it real well.
Lowther type speakers generally will reach only as low as the lower 40's in bass response. The driver's resonant frequency is about 36Hz, and there is a large impedance spike at that point, that limits performance below that. However, everything else is quite nice for a SET amp. If you can live with 40Hz, fine,then Lowthers will do beautifully.
