After reviewing, measuring, comparing so many DAC, players, amps, preamps, I don't think Peter Aczel was remotely interested in doing anymore. TAC has not been reviewing anything since forever.
DACs & players have only improved in technology since then. For example, the SNR of the bottom of the line DAC is like 112dB and the top of the line DAC is like 132dB. Yes, clearly there is a difference in spec. But even the bottom of the line is already excellent.
I agree that certain applications are not as equal. I am not thrilled about the DAC in PCs and sound cards. But players from $200+ (like Oppo) and AVR from $600+ have solid DAC implementation.
