Magnitude.

There are ways to get practically zero hum (way down in the microvolt range) from DHT tubes. This "room filling" remark is just as unfair and misleading as anything Steve is trying to combat to get market penetration for his amps. I have a standard hum balance pot on my 300B amps and I get around 2 mV noise output. It requires a quick check once every 2-3 days as the position does change a little due to thermal expansion/contraction etc. There are ways that can reduce that amount anywhere from 6-12dB. I can't hear hum from my setup unless I have my ear 6 inches from the speaker and I certainly can't hear a damn thing in my listening chair. My refrigerator in another room makes more noise. Hell, I even have a DHT for a preamp tube. Using a DHT for a preamp tube is even more critical to get hum and noise down because everything gets amplified in the system about 50 times afterwards. Guess what? Quiet as a cemetary. DHT's can be made stone quiet folks. What a f***ing suprise, eh?

Now, did I ever say a SE EL34 or KT88 cannot sound good? No. I'm sure they can be made to sound lovely in some systems. I just find Steve's logic as a contradiction since all these folks who formed a preference towards DHT after trying SE EL34/KT88/6L6/EL84 just "didn't know how to use them." As for your "famous" person/amp story, why didn't you tell the person that the humming was noticeable? Why do you automatically attribute the cause of the hum to the 300B amp? Perhaps it was a ground loop. You just never know until you bring it up and investigate.
