Hybrid Tube & SS

Well, there are many speakers that work best when driven by SS amplification, wether from a hybrid integrated or a tube preamp paired with a SS amp.  There are speakers that can swing either way, thus it becomes very subjective as to what one prefers.
Then there are some high impedance speakers that beg for tube amplification.

My Esoteic MG10 are the SS type, my Tannoy Sterlings can swing, currently drive both with a tube pre into a SS amp.

Personally IMO good solid state amps have no need for a tube preamp. The key word is good SS. If you want a more profound change using tubes, I think a tube amp has more impact than a tube preamp.  IMHO

Saw a video from PS Audio saying that tubes are for preamps and SS is for amplification and that we are best to let each do their job.

I’ve found there are gazillions of variables in this hobby/disease and very few absolutes. I find when people say things like this they usually either don’t know what they’re talking about or can’t trust their own ears enough to figure things out for themselves, so relying on silly and oversimplified rules helps them feel better. I will say this though — I think it’s better to use a quality SS amp than push a tube amp past its comfort zone. That’s all I got.
