Your review of the BADA converter and the playback of high resolution music files it allows is fascinating. You make a point that the best sound was when the BADA converter was connected directly to the power amplifiers. I would like to read your further thoughts on this topic. The accepted audiophile wisdom is that the best sound would include a preamplifier. I would think that the Spectral DMC 30 SS ( state of the art volume control and high bias, discrete line stage ) driving long MIT interconnect cables would outperform the D to A ( with an integrated circuit based line stage) used alone. I look forward to hearing high resolution digital playback as you describe - I expect it to be an emotional experience!
