Can Tube Amps be Used for Home Theater?

I like tubes in home theatre, but only with 90 db or higher efficency speakers. I have also used tubes just for the center channel to good effect.....input sensitivity was matched at 100k. I like to bi-amp as well with tubes driving the top end, SS on the bottom. After a few tube changes though, the Bryston amps sound very good again.
Thus, I have two HT systems, one for music DVD's, the other for movies. I don't need tubes to hear, a car crash or gun shots. Do the right thing.....two systems. Jallen

Whart- Thank you very much for such a detailed response.

I run my Cable Box and a Modified OPPO 95 to my ARCAM FMJ888 via HDMI for movies. So far I am very pleased with the results. I just bought a CARY 7.250 7 channel amp for multi channel listening. I decided to skip Tubes after reading opinions on this post. Plus I got a great deal on this Amp.

For two channel listening I go analogue from the OPPO to the ARCAM and select “direct” and the sound through my Dragons is very pleasing and again I am very happy.

I guess I could look into upgrading my mono Dragons to Hybrids when things settle down. That should be fun.

Ridom - How much were those amps? They look very interesting.

They were about $4,000. Google them. I am using them with planars (Analysis Audio Omega) and leave them always on. I did not open them, but I think they have one 6H30 each. Incredible sound. They are made by the Analysis Audio distributor

I also have the butler audio amp which replaced the most expensive Classe amp. I like the butler better. I am using electrostatic speakers all around with a JL audio sub.
