Amplifi cation
Bipolar or F.E.T., class A or switching, O.T.L. or transformer isolated, one bottle single ended triodes or 500 Watt “who needs central
heating” pentodes; Defi nition loudspeakers will work well with most all audio amplifi cation designs. Sure some will prefer one over
another, for assistance on which might fi t your idea of playback fi delity please give us a call, we’re hear to help.
Loudspeaker cable
The most common abuse in hi-fi is to use cable as a form of tone control. Doing so usually leads to frustration and further loss of
fi delity. When cable affects timbre it affects timing, phase, frequency response, and so on. Timbre problems are usually solved
with loudspeaker break-in and correct loudspeaker placement. One last note on tonality and cable, if the cable has good properties
relative to phase, gain, group delay, impedance, and bandwidth, it will likely convey with fi delity the transmitted emotion and color.
While insulation, jacket materials, pigments, conductor shape, metallurgy and structure are important, all pale compared to the
infl uence of fi eld, virtual ground plane and conductor relational geometry. This fi nal cable geometry largely determines measured
attributes. Defi nition Mk2 features a specifi cally engineered B3 silver alloy cable for internal hook-up. We strongly recommend the
use of our Ibis, Libtec or Wax loudspeaker cable terminated with our pure copper spade lugs.
Improvements that will be noticed from well engineered cables should include bass depth and resolution, system noise fl oor,
harmonic structure and timbre, attack, soundstage size and accuracy, easy of listening—simply a lot closer to the recorded event.
Maintenance and cleaning of fi nish
Matte fi nishes, just dust and clean —no wax. For gloss, do not wax your speakers during the fi rst three months of ownership, six if it’s
a cold climate. Likely nothing will happen but under perfect conditions it can trap solvents that will otherwise escape the clearcoat.
For cleaning and dusting of your Defi nition Mk2 loudspeaker simply use a clean damp cotton towel or clean microfi ber cloth.
All fi nishes offered on the Defi nition Mk2 are very durable, waterproof, and will remain so for decades to come.
Dusting of the 10” drivers should only be done with hand-held compressed air as used in photograph and sensitive electronics
dusting.
Maintenance and cleaning of binding post terminals
The unplated pure copper binding post terminals should be cleaned once or twice a year using the supplied polishing compound.
Once you have cleaned and polished the binding posts and spade lugs (if you are also using our unplated pure copper spade lugs)
avoid touching the spades or the binding posts. Keeping the contacts free of the halides from on your skin help ensure a long term
and trouble free connection.
Instructions for cleaning and polishing the binding posts
Wash your hands with soap and water prior to cleaning the terminals.
1.
Completely remove the machined aluminum binding post nut and black plastic terminal block.
2.
This will make for easy access of the pure copper lugs.
Using the supplied polish cloth (jar labeled “polish”), rub the exposed copper lug until it is clean, usually about 15 - 30
3.
seconds is all that is needed.
Wipe the polish off the copper lugs with the supplied white buffi ng cloth. (DO NOT WASH THE POLISH OFF, POLISH MUST BE
4.
REMOVED BY BUFFING ONLY.)
Refi t the black plastic terminal block and machined aluminum binding post nut.
5.
Again wash your hands with soap and water. The polishing does contain a small amount of petroleum distillate.
6.
If you are also using our loudspeaker cable fi tted with our pure copper spade lugs, we recommend that you clean your spades the
same time that you clean your Druid binding posts. Polish each spade for 15 to 30 seconds then buff with the white buffi ng cloth.
