You did not want tube recommendations, but so far, out of the preceding 7 responses, six have said tubes. Now make that 7 out of 8.
There are some people who absolutely will not mess with tubes due to the hassle/heat/replacement, etc. I was one of them until I heard what they do. After hearing, some decide it is still not worth it, but you must decide that from your own observations and feelings, not from what you read.
