Jolida JD9 Phonograph Stage Tube Pre-Amplifier

Jolida's JD 9 Phonograph Stage Tube Pre-Amplifier is an example of state-of-the-art vacuum tube technology as it exists today.  This JD 9 is the original 2012 issue of this amp. It is housed in a heli-arc welded chassis and uses two (2) 12AX7 output tubes. For more info, see the specs below. This piece was purchased on 2/23/2012 and has approximately 300 hours of operation so the tubes and
other components have been adequately burned in for optimum
amplification. The reason for selling is that, even though I feel the sound of vinyl is
the best audio available, I tired of cleaning LP's and changing records
during playback. So two (2) years ago I converted to the convenience of
listening to digital by ripping all my cd's and vinyl to FLAC files on a
hard drive which I listen to using JRiver Media Center on my computer, a
headphone amp, a Meridian DAC and a high end pair of Byerdynamic
headphones. You may contact me at Email "[email protected]" or by
