First of all I want to thank you all for the great feedback. It really answers most of my questions. It seems like in the home-theatre setup I intend to use the amps, and the speakers which I intend to use them with, solid state will make more sense and is probably more practical. If I quickly want to watch a movie it will be frustrating to allow for warm-up time first. In South Africa, where I live, it might also be difficult and expensive to find replacement tubes. I am nevertheless still very much intrigued by tubes and will have to go that route soon. I have a normal two channel system in my bedroom with B&W 804 diamonds. Maybe I should start with a smaller tube amp there ? Perhaps any thoughts on what I can use on them ? Perhaps a ARC of around 100 Watts into 8 ohms ?
The message which I am getting from your responses, and please correct me if I am wrong; Tubes are like a beautiful but difficult woman. The times she brakes your heart make the good times even more special.
Thanks again for the great response to my first posting.
