Phasemation T-300 Stereo Moving Coil Step-Up Transformer
The T-300 was developed in-house by Phasemation and achieves excellent technical and sound performance by winding the transformers with extra-thick low-loss copper wires (Primary: 0.32mm dia., Secondary 0.12mm dia.) around a large EI core made of thick 78% super permalloy core material. This results in the best lower-band-linearity and the highest step-up efficiency. In addition, the winding structure of the transformer layers has resulted in a wider bandwidth, with excellent phase characteristics.
Phase distortion in the audible band has been reduced drastically and auditory localisation has also been optimised. By adding a shield board at the centre of chassis to divide the left from the right, channel separation has been substantially improved.
Phasemation have paid great attention to minimising the T-300’s susceptibility to outside vibration. The step-up transformers are supported with polyethylene foam, which provides good physical isolation as well as preventing cavity resonance inside the case.
The chassis base and top covers are made from 1.2mm and 1.6 mm steel plates, with copper plating and smart black finishing. All the parts are assembled with the stainless-steel non-magnetic screws to minimise the influence of any magnetic distortion, to maintain a clear sound character.
How Does it Sound?
Even before plugging anything into the T-300, it impresses by being substantially bigger and heavier than the photos (and modest pricing) might suggest. But, we are glad to report that the sound quality and musical reproduction through the T-300 is pretty much as good as anything we’ve heard. Yes, a Miyajima ETR-STEREO is more flexible and a great sounding thing, but for anyone needing a quiet, hum-free and musical SUT with around 20x gain, the Phasemation T-300 is almost guaranteed to delight. Our demonstration Phasemation PP-300 acquires a real depth of sound with a lovely organic and free-flowing musical character that is really rather special. It is a copper-bottomed musical delight and is very highly recommended.
