Tvad,
Of 30 odd mod/test cycles I've been through with the SCD-1, all but one or two changes were steps in a positive direction without any downside. The one or two mods I would consider "flavor" preferences-- i.e., mods that improve in one area while compromising in another, as you describe, usually in a trade-off between resolution & musicality-- were later corrected with improvements to power source. The experience of continuous improvement with a single player convinces me that absolute, not relative, comparisons are applicable when judging CDPs. Give me a player with high resolution, and mod it to add musicality. After the modding is done, one is finally up against the brick wall of the type of DAC or upsampler and the limitations of basic transport mechanism-- which doubtless together define the ultimate "flavor" of the machine. But there are so many compromises in most commercial players that short of SOTA, judging their quality based on type of DAC or upsampler is likely a red herring. This is why I'm inclined to restrict use of the "flavor" adjective to the best machines.
