Hi Jonathan.
.
The first Transfigurations had the single ring-magnet configuration, which to me appears generally unchanged with the present Orpheus and Temper designs. I used a Transfiguration in the early 1990s, and it was of this type.My understanding is that the Temper line (Supreme,V, W) and Orpheus all employ the ring magnet, while the others, Esprit, Spirit 2, Axia, and Phoenix, use the double-ring magnet (which is a confusing terminology since they are quite different in design and concept.) The "double ring" design remids me of a Colibri just befor vdH removed the front magnet ;-) while the "single-ring" magnet is really more of a tube or cylinder, into which the whole coil is fitted -- but you know that ;-) I do think the two-magnet design precedes the single-ring (not absolutely sure) and is the one still used in their less expensive units. As for the tension string, all I know is I never saw one in any of the Temper series diagrams.
FWIW, it is perfectly valid to classify the majority of MC cartridges that rely on tension wire suspensions as having push-pull dampers.I don't think I can agree with that, because when you 'pre-compress' the suspension material by applying tension to the string/wire, the suspension material will always be in compression (just more or less of it.) Without such 'pre-compression', the suspension material will be in either tension OR compression depending on the position of the coil as the stylus tracks the groove. What's important here is that this strategy moves the 'virtual pivot point' closer to the axis of the coil, instead of the traditional position behind the coil. Miyajima and (I think) ZYX are two other makers who have incorporated this idea as well, although using different methods to achieve it.
