On another note, I finally got the Grimm TPR and it works just fine as an AES cable from the BDP-1 to the DAC. The length of the cable is 2 feet (60 cm), which is shorter than the recommended 1.5m. Initially I tried one pair of TPR replacing the 2549 for analog run. Next I put another TPR on the digital input for AES. So adding TPR at stages.
The TPR definitely has a different feel than both of the Mogami 2549 and 3173 for analog. For digital, so far not hearing anything fatiguing or jittery that I would get with Mogami 2964 SPDIF cable at 2 feet length, which is the same length as the TPR. So it could be the difference between cable and/or simply AES vs. SPDIF connection. Just initial impressions. All the various Mogami cables have hundreds of hours on them, meanwhile the TPR is fresh out of the box.
The difference in presentation and vocals are definitely something else.
