Tube pre with a SS power amp is a great way to drive power hungry speakers and get that great tube midrange and high end and a solid bass. I have a cary slp 05 and classe ca2300 driving some Thiel 3.7s. Nice wide and deep sound stage, very natural sounding. Not edgy or fatiguing at all. I would recommend this combo (tube pre ss power) to any one. Just make sure you pay attention to the output impedance of the pre and the input of your power amp. Need to get a good match.
If I'm looking for "Tube Sound", why would I put a Tube Pre in front of a SS amp?
I'm purposefully not specifying speakers as I would like to know in general terms the arguments for and against. So, to the degree that speaker characteristics could also influence the choice, please explain. FWIW, I do not know a phase angle from an impedance curve so I will try and educate myself as we go along. Hopefully, others may benefit too.
