Why did you lean one way or the other

Started with class a/b SS, moved on to class a SS, then to push pull tubes, next to SET. My experience with tubes and reliability is the higher the output the more heat and issues with reliability, heat not good for reliability. I still dabble with ss from time to time, purchased Pass XP22 pre and while it was nice not quite there in my setup. 

As much as this is about tubes vs ss, speaker, amp interface is the final arbiter equipment wise, the right tool for the job. Beyond that its listener preference, I've always enjoyed the added texture and color tubes (2nd order harmonics) bring to the presentation. Also prefer the way tubes sound stage and image, slightly less defined image outlines. 

Having said this, I've heard quite compelling presentations from both tube and ss systems, if I had the funds and room I'd have at least two reference systems, or perhaps three or four or five or whatever. 

They both have their merits, it's great to make your own choices.  If I had another decent room, I'd have one of each.

I prefer the detail of a SS system as well as not having to worry with tube paranoia.  The downside is that it has taken a significant amount of time and trail/error to get my system dialed in.  I prefer to be able to discriminate between good/bad recordings and enjoy hearing detail in tracks I have listened to for years that I never heard before.  Some with expensive tube systems say they prefer it because it makes even bad recordings sound good.  That seems counterintuitive to me but an example of what makes this hobby so interesting.

Another tube-pre SS-power person. There is also a visual part to it. In case of tube and SS gear of equal sound&price, I will lean towards tube for esthetics. I also like the idea of fine tuning sound with tube rolling.
