Used rare Cascade X15 stereo ribbon microphone in its original case with all accessories.  This is an amazing mic with that classic ribbon warmth in excellent condition.  Accessories include aluminum case, 5-pin XLR cable, 5-pin to dual 3-pin stereo splitter box, shockmount microphone clip, windscreen, padded zipper case, and branded polishing cloth.  Please see photos.

Here is the manufacturer's description: The X-15 Stereo Ribbon Microphone houses two separate matched ribbon motors that are positioned one above the other.  The elements are offset 90 degrees and are configured in the Blumlein setup.  Stereo separation is superb and off-axis coloration is minimal.  Add in the excellent sensitivity and frequency response range and the X-15 is ready for the big leagues.  The fit and finish are of top quality and includes a premium suspension shockmount, thick padded vinyl pouch and an upgraded aluminum case.  A 5-pin cable is included, the cable connects to a metal splitter box where two separate XLR connectors give access to the upper and lower ribbons.  Unlike most ribbon motors designed today with an offset ribbon element the new Cascade X-15 houses two hand-tuned ribon elements that incorporate the legendary symmetrical ribbon design.  This design offers a true figure 8 pattern.  The corrugated aluminum membrane itself is positioned in the center from front to back, thus producing a balanced audio input signal to both sides of the ribbon assembly.
