Phasemation T-320 MC Step-Up Transformer Passive MC step-up transformer with 26 dB gain, front-panel bypass switch, and solid build quality Suited to cartridges with an output impedance of between 1.5 and 40 ohms, the T-320 is a compact, rigidly built step-up transformer designed to elevate MC cartridge playback. A front-panel bypass switch allows the easy use of MM as well in the system. The T-320's chassis follows Phasemation’s higher-end designs with a 10 mm slanted aluminum face and copper-plated panels to reduce resonance and magnetic interference. This is a passive, low-noise design tailored for serious analog systems. At its core is Phasemation’s original split-winding transformer architecture: low-loss, ultra-thick copper windings on a large EI core. The result is outstanding wide-band frequency and phase characteristics with strong bass linearity and clear spatial imaging across the audible range. Gain is fixed at 26 dB. Compared to the T-550, the T-320 is more compact and includes a front-panel bypass switch for MM use, but does not offer balanced inputs or the same level of vibration and hum suppression. Who Needs a SUT? If you have a low-output moving coil cartridge, a step-up transformer allows you to passively increase the output of the cartridge, letting you use a moving magnet input on a phonostage, which has far less active gain, and therefore far less chance to magnify noise. A SUT has to be very carefully matched to your cartridge, so make sure you talk to our analog team before buying one.
