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!

Sounds like you have ground loop issue. Also, a 300B SET can't really drive the 87db proac. This sounds like equipment mismatch issue.

There are two things you need to keep in mind to match speakers and amp: sensitivity and impedance. The impedance dip are often overlooked.

I prefer the Mac Mc240 driving the ProAc 2.5s. This is just my taste.

Tomyran, I don't have issue with Sun Audio SV2A3 in my setup ( I borrowed this amp from a friend of my ) Definitely no buzz or any noise. with my Citation I preamp.
I'm using it with Jensen coaxial speakers and they sounded fine except for the bass. I prefer deeper and larger volume of bass from that 2A3.
