My listening chair is 9 feet from the plane of my speakers. From the chair, I can hear no hiss, hum, buzz or anything from my system which includes the Lamm LL2 Deluxe, especially when the music begins playing. I can hear a very slight tube hiss within about 3-4 feet of my 90dB speakers, but that is of no consequence to me because of how good the Lamm gear sounds. With your higher efficiency speakers, you may hear that tube hiss further out. Therefore, if the noise level is of high importance to you, I again recommend you consider trying the Tom Evans preamp with Pulse (be sure to get a Lithos 7 model). I have owned two of these and with either I could hear nothing at all from my speakers outside of about one foot away.....nothing except when music was playing. So, if quietness is of major importance to you, I can make no better recommendation of the preamps I have owned than the Tom Evans. They have body, fullness, and a natural sound that frequently eludes SS preamps. While there may be other SS preamps that meet your needs, I have not heard them. If you get a chance to audition, try the TE Lithos 7, Vibe with Pulse.
