Micro Seiki BL-51

Little Micro quite different from the later belt-driven ultra vinyl spinners, the BL-51 was however one of the brand's bestselling spinner, along with the BL-91.

The light 2,3kg platter is centered on a very thick 1,6cm shaft, the concentricity of which is machined down to 0,4 microns. The entire high-precision polished ball bearing + shaft is suspended in a secluded oil-bath - avoids periodic servicing and remains unaffected by temperature changes or aging.

The drive is a servo-controlled DC motor which drives the platter by way of a specially engineered low-tension belt made of carbon/urethane compound ; this belt is ground to a precise 0,45mm thickness.

The base is, ahhh, genuine plywood, not the all-too-frequent compressed wood particles - plywood remains one of the best acoustical damping materials.
Finish is hand-rubbed ebony veneer for a touch of discrete classiness.
Optional tonearm delivered was the low-mass Micro MA-701.

Otherwise, the Micro blank armboard could welcome the Micro MA-707, SME 3009, Infinity Black Widow, ADC LMF-1 & LMF-2, Grace G-704, G-707 & G-714 and the Stax UA-7 - the latter being made by... yes : Micro Seiki :)

...but one could also go for something else than the usual suspected suspects for a little more excitement and welcome change of perspective : a Sony PUA-1600S would do just as fine !
