bullet AVSHOWROOMS review - 11-15-2012

........... has created what may be the world's finest phono stage.... The 3D effect is extraordinary with this unit- almost tube like without the noise and with the frequency response that only SS can provide..... The hallmark of the Ruby is its low noise floor, it is DEAD quiet............

bullet TONE AUDIO PUBLICATIONS - DEC - 2015

Type in page 72 in the window for the Ruby review titled

"... A Touch of Royalty ..."

"... This is a very special preamplifier, offering performance rivaling the world's finest ..."

" ... In the context of the four different systems at my disposal...... the main characteristics of the Ruby that came through loud and clear.... were this preamplifiers spectacular bass drive, extension and control along with an incredibly deep soundstage ... "

" ... Of the preamplifiers in my collection, I`d compare it the most closely to the $33,000 Koda K-10, with an almost absence of `sound` but with a few drops more of tonal saturation... "

OPAL preamplifier

bullet The Absolute Sound - issue 143 (August/September 2003).

"....Even in its high-gain setting, the Coral via my 103dB Avantgardes was very quiet.... "
