This review is for Herbie's RX-9 Tube Dampers. Rather than put dampers on all tubes, I chose to put a pair on my input tubes in my modified Monarchy NM24 tube dac and a pair on my tubes in the V2 and V7 positions which amplify and buffer the RIAA output in the phono section of my restored Citation 1 preamp. I wanted to hear how much difference my system's presentation would be just treating the source of my digital and my analog.
My digital consists of a Mark Levinson 390s as a transport that feeds the modified Monarchy NM24 via the Creative Concept digital cable. The Monarchy NM24 is powered by the Monarchy Regenerator that I set at 120 Hz and 117 v. The tubes in my Monarchy NM24 Dac are 1965 Siemens Halski CCa.
My analog consists of a Thorens 126 MKIII that has a modified tonearm with a 103r cartridge which feeds an Allnic AUT-2000 SUT which feeds the phono section of the Citation 1. The tubes in the Citation 1 are 1957 Mullard MC-1s.
Herbie's RX-9 Tube Dampers resolve recorded events on a higher level demonstrating a greater revelation of that event. The dampers reveal nuances, coherence, texture, tonality, Prat, etc, which provide a greater sense of reality. The dampers enhance your system's "Musicality" providing an emotional connection that contributes to a heightened level of musical enjoyment.
