That’s what the dealers tells to their customers when selling the SPU Classics, i was hooked, but i didn’t worked out for me. The terms "warm and musical" sounds much better in my mind, but in reality i would not call the sound of SPU Classics "musical", i would call it boring in my tube system. But it is always important to try something different in comparison. I don't think we have many SPU followers here on audiogon, people are championing different cartridges, at least it was not easy for me to find anything about SPU on here when i was looking for it. I think the design of the Miyajima (Cross Coil) is an advantage over the oldschool SPU, but the Miyajima belongs to the group of "warm and musical" cartridges too, probably much better than SPU. The Fidelity-Research FR-7f (Air Core Coil) is also unique design and it's pure majic.
