I have a 2 channel HT with a tube integrated a Consonance Ref 150...tube output stage....tube is over two years old now and costs $14 to replace...the sound is not harsh but smooth and refined......speakers are VonSchweikert VR1's with the VS1 sub....Oppo DVD player. I would not get an integrated with a forest of tubes but something pretty simple with easily and cheaply replaced tubes...there are many options...call Stephen Monte at Quest for Sound in Bristol PA he was a big VS dealer and is a tube guy...he'll tell you what will work
