I have vintage 12" monitor golds in custom cabinets and have had great results with single ended 300b,845, and pushpull EL84's. The Tannoys although being very musical speakers, are also very revealing of their upstream electronics feeding them and certainly do show the differences in all three amplifiers. The main thing is that they are easy to drive, so just pick out a quality amp whose house sound you like and the Tannoys will gladly give it to you.
