I need a quiet tube amp

Hey guys...I need suggestions on quiet tube amps (SET and P/P suggestions are welcome). I know some very respected makes that create quite a bit of noise with efficient speakers and am wondering what's out there that's good sounding, well built, and quiet. I've got a 300B amp from a well regarded Japanese company that gets noisy at high levels with my 87db ProAcs. I can even slightly hear the buzzing at seat position 9 ft away. I've owned other tube amps that didn't do this and am getting a 2nd amp for the system and want something as quiet as possible. Thanks in advance, Audigoners!

I agree with Marakanetz. What are you doing making a 300b work so hard. You should be looking at something with more like 100 watts/channel. Much of your noise is from having the volume so high. I'll bet these amps are silent on a 94db speaker??????????
Borrow some high powered amps and check it out.
@87db:
1 watt = 87db
2 watts = 90db
4 watts = 93db
8 watts = 96db
16 watts = 99db
I know your amps can't put out more than this!
To get to THX levels with 87db speakers would take over 220 watts for 110db-your poor 300b's :( Wanna trade for my 120 mono's?
