ok it took me a while to process these but see if you can pick them out. ill give it a few days before i upload the key to which samples are which

sample 1 = OG wav before being played digitally thru benchmark dac1. 4 tracks of different sound. all were 16/44 flac releases other than the steely dan track which was originally played thru the DAC at 24/96. i resampled it to fit it into a single wav after the fact for comp purposes
samples 2 thru 9 are all analog into one of the following recorded at 24/48, try to guess:
-balanced out of DAC1(~+24 dBU)>SPDR analog in
-balanced out of DAC1(~+24 dBU)>AD2K>spdif> known good bit bucket
-balanced out of DAC1(~+24 dBU)>AD2K>AES>SPDR (resampling AES input)
-unbalanced out of DAC1(~+13 dBU)>Edirol R07
-balanced out of DAC1 > SPDR at highest level i could (minimum gain on recorder). I ran the SPDR input level as low as i could and cranked the output level of the DAC1 as high as i could to get it the hottest signal i could with decent levels peaking above -10 dBFS
-simultaneous to the SPDR high level test above, I ran unbalanced out of DAC1 > sony PCM-A10 at what would be a level about -11 dBU below the balanced levels to SPDR above. (low gain on recorder, decent levels peaking above -10 dBFS).
-balanced out of DAC1 > SPDR at low level (max gain on recorder). I ran the SPDR input level at its max (max gain on recorder) and turned the output level of the DAC1 as low as i could to get it the lowest signal i could that the SPDR could still record at decent levels peaking above -10 dBFS)
-simultaneous to the SPDR low level test above, I ran unbalanced out of DAC1 > sony PCM-A10 at what would be a level about -11 dBU below the balanced levels to SPDR above. (high gain on recorder, decent levels peaking above -10 dBFS)
original recorded files are provided as well as files normalized in soundforge to match OG wav input (as close as possible without hitting FSD, as original wav was <0.5 dB peaks, and some of the ADCs took liberties). i bookended the 4 songs with 10 second silent tracks, and so 5-10 seconds of silence from DAC are included at the beginning and end of each sample so you can check out the noise floor if you desire. maybe save that for last after you pick a favorite
