The SPU #1 models, with their universal connector, ensure 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. With their linearity and full bodies, the SPU #1 models are a perfect solution for the playback of stereo recordings. Sonically, the SPU #1 models are genuine SPUs, known for their full-bodied and powerful music image, minimum of inter-modulation distortion and an impressive channel separation.
