Option 1: $499.99 for one matched pair of Sophia Electric 45-01 output transformers -- clear, rich sound similar to more expensive 45-03/05, but built in a smaller core and smaller gauge of wires.
Option 3: $699.99 for one matched pair of Sophia Electric 45-03 output transformers -- luxury of wide dynamic range, high resolution without being bright, very natural sound, truly 3-dimensional sound stage, much larger iron core and high end lab OFC copper wire, real vintage flavor from vintage core material. Money well spent for level 03.
Option 5: $899.99 for one matched pair of Sophia Electric 45-05 output transformers -- flagship model, truly exotic materials (WE core, solo crystal OFC wire) for out of this world performance. It is designed for those who always want the top of line model and willing to pay for the bill. Customer-made on order.
