Ortofon SPU 1 E Moving Coil Cartridge

Ortofon SPU 1 E 

The SPU 1 E and S models are a remarkable embodiment of the classic Moving Coil technology, offering an ideal solution for playing back a wide range of stereo recordings, from the early classics to modern and contemporary pieces, with an outstanding price-to-performance ratio. 

Their universal connector ensures the ability to mount the units in a wider range of tonearms with universal (SME) mount, e.g. Ortofon TA-110 and TA-210 tonearms. The combination of SPU 1, ST-7 Moving Coil transformer and TA-110/TA-210 tonearms gives a supreme experience. 

The SPU 1 E features an elliptical stylus, with a profile providing more detailed sound reproduction and expansive imaging.

Sonically, the SPU 1 models are genuine SPUs, known for their full-bodied and powerful music image, minimum of intermodulation distortion and an impressive channel separation.

With their linearity and full bodies, the SPU #1 models are a perfect solution for the playback of stereo recordings.
