Hashimoto
HC-203U SE output transformer
Information
found on the internet:
http://jelabs.blogspot.nl/2013/12/hashimoto-hc-203u-se-output-transformer.html
In
the past I have used a pair of H20-14U for the JEL SE10dx
monos project and I'm also very familiar with the not
quite so Simple 45 fitted with H20-7Us built by Setup
2 for the November Hi-Fi Show head honcho. Today I will
report on the entry level SE OPT offering from Hashimoto.
Technical
and listening tests were conducted using the JEL SE2A3DX
circuit.
Aside from a 3.71mm difference in lamination thickness
and use of flying leads instead of terminals (U-808)
these two transformers seem to be technical and physical
twins.
But sonically they're not even distant cousins. The
HC-203U is a bold performer and gives a front row presentation.
Given its rather small stature, it has bass slam and
definition that I associate with transformers twice
its size. Vocals are presented in a lifelike manner
and there is enough extension in the highs to give a
sense of spaciousness and airiness.
The Hashimoto HC-203U is what I always wanted the Tango
U-808 to be.
