I have been using an SFT-1 for about 3 years and I have not had any problems with it at all. The build quality is outstanding. I too have not experienced bright or harsh sounding qualities from the unit. It is very neutral, maybe even a little laid back. Keep in mind that the DAC which you choose to couple with it may affect the final outcome of the sound (as might the digital cable). Overall, I don't think that you can go wrong with the SFT-1, especially at pre-owned prices.
