I use a Bob's Devices Cinemag SUT, among other transformers, with Denon 103 and Ortofon SPU cartridges. The Cinemag has quite an objective sound, not dark nor florid, but harmonically rich and tonally correct. I have Koetsu and EAR transformers, and have used many other notable transformers in the past. The Cinemag is quietly correct, unerringly musical, detailed in the way natural acoustic music is enlivened by transient events, and with two-position gain, eminently matchable to a range of cartridges. It works quite well with Koetsu, SPU and has a special affinity for Denon moving coils.
