I would go with something like a C-29, or even the 28. The C-29 is my hands down favorite Mac preamp. The phone section is stellar, the tone controls (wonderful when needed) are as close to perfect as one could imagine. This preamp soundstage is wide and deep.
They don't come up often in the used market (like the C-27), but are worth seeking out. Conversely any of the older Mac Preamps would be a great choice with your amp. C-22, C-26, C-27, C-29, all have that glorious phone stage and signature sound.. I wouldn't trip over tubes vs. solid state when considering Mac preamps. Either way is a win.
