The Art of Passive Gain: Precision Engineering for the Analog Purist
The Phasemation T-300 represents a pinnacle of Japanese "Monozukuri" (craftsmanship) in the realm of analog playback. Originally released to succeed the legendary T-3, the T-300 was designed with a single goal: to extract the microscopic nuances of Moving Coil cartridges without the electronic noise floor inherent in active head-amplifiers. By utilizing a massive EI core and proprietary winding techniques, the T-300 delivers a "vitality" and spatial realism that has earned it multiple prestigious awards, including the Stereo Sound Best Buy and the Audio Excellence Award.
Phasemation T-300 SUT
In-House Custom Transformer Architecture
Unlike many manufacturers who source off-the-shelf transformers, Phasemation develops their SUTs entirely in-house.The T-300 features a gigantic EI core made of 0.2mm thick 78% Super Permalloy. This core is wound with ultra-thick, low-loss copper wire (Primary: 0.32φ, Secondary: 0.12φ) in a unique divided-layer winding structure. This specialized geometry minimizes phase distortion and maximizes high-frequency extension, ensuring the "fastest" possible rise time for transient signals.
Resonance-Free "Floating" Chassis
Mechanical vibration is the enemy of low-level signals. The T-300 utilizes a sophisticated multi-material damping system. The internal transformer is entirely encapsulated in high-density polyethylene foam, which physically "floats" the sensitive coils away from the outer chassis. This serves two purposes: it prevents external micro-vibrations from reaching the transformer and eliminates internal cavity resonance (the "echo" effect often found in hollow metal enclosures).
Magnetic & Electrical Shielding
To combat induction hum, the T-300 is housed in a heavy-duty steel chassis. The base is 1.2mm thick and the top cover is 1.6mm thick, both treated with pure copper plating before finishing. This copper-plated steel sandwich provides an exceptional barrier against both RFI and magnetic interference. Furthermore, the internal layout includes a central shield board to maximize channel separation and soundstage width.
Audiophile Grade Connectivity
The T-300 is equipped with premium machined gold-plated RCA terminals. Every screw used in the assembly is made of non-magnetic stainless steel to ensure that no parasitic magnetic fields interfere with the transformer's flux.
