Product Outline and Concept
Pursuing our knowledge for cultivating the T-550, which was highly evaluated after it was released in 2020, we polished its sound quality by adding an MM/MC changing switch making it more convenient. The same 10mm thick aluminum slant panel which was used for the grand model T-550 is adopted and designed it so that it gives out high quality.
Features
I. Adopting a strong chassis structure that follows the T-550 design
The front panel is a rigid box structure having a 10mm thick slanted aluminum panel, a 1.2mm thick copper plating board chassis and a 1.2mm thick copper plating cover. Non-magnetic stainless steel screws are used for assembly to ensure rigidity and reduce magnetic distortion.
Ⅱ. MC step-up transformer due to a special split winding structure developed by us.
We adopted our original divided winding wire structure. By winding a low-loss ultra-thick copper wire around a large EI core made of a 0.2mm thick 78% permalloy material, we brought into effect an outstanding frequency characteristic and phase characteristic at a wide band. This achieves outstanding characteristics of excellent linearity for low frequency and high-efficiency gain which reduces phase distortion in the audible band range and brings about a threadlike spatial expression and clearer sound image localization that can fill vitality over the entire range.
Ⅲ. Loaded with an MM/MC changing switch
An MM and MC changing switch is located on the front panel which makes it more useful.
