I sell 2 sets of three SPIRA II Ultra Tuning Feet "Heavy Duty" version (not standard version) "in mint conditions never used but open package bags to check pieces and taking pictures only". I bought several sets for my 2nd audio equipment but these lasts are not necessary already for me since I sold it finally.
The SPIRA II H.D. is the high performance turning feet set with the highest cost/performance ratio in the current Hi-Fi audio market. Upon installation, the SPIRA II H.D. immediately improves sonic performance by rendering solider bass and higher resolution for audiophile dreams. The SPIRA II H.D. is designed to actively absorb, dissipate, drain, and eliminate the unwanted vibration and resonance energy from an applied audio component. Unlike competing tuning feet products only with a single mechanism, the SPIRA II H.D.boasts multiple structures and mechanisms to control vibration and resonance energy. The SPIRA II H.D. is unique suspension mechanism offers the best absorption and quelling performance of initial vibration and resonance energy. The suspension mechanism employs an exclusive and patented multiple spiral disc springs with the various modulus of elasticity. The remained vibration and resonance energy after the suspension treatment is dissipated and eliminated through the precision-devised triple ceramic ball mechanism which converts the vibration energy into heat energy. As its load capacity for each one set of three is up to 100lbs or 50Kg, its height is 1.2 inches (31 mm) and its wide is 2.4 inches (60 mm). The SPIRA II H.D. can be readily applied under various audio rack or shelf environment to improve the performance of CD players, CD transports, DA converters, preamps, turntables, etc. The effect of the SPIRA II H.D. is immediate under any environment and clearly recognizable even by a novice audiophile.
These sets of SPIRA II H.D. add greater finesse in the depiction of performers in space with better separation of instruments and increased layering in an already enhanced soundstage. Cymbals now shimmered with greater clarity, without any harshness, decaying even longer without any undue emphasis and with even more obvious harmonic richness. These increased textural details are evident right across the spectrum from the dramatic bowed bass and tympani to the harmonic richness of the gut strung Renaissance lute...they work great really. The SPIRA II H.D. also won the recommendation list by the STEREO TIMES as for the 2012 Audiophile Christmas Gift.
