@roberto2 lent me his OCK-2 during two weeks, so I could compare it to my OCK-1.
I compared them with two setups :
- EtherRegen (+10 mhz) > Allo USBridge Sig > Di-20 HE (+10 mhz) > R26 (+10 mhz)
- EtherRegen (+10 mhz) > R26 (+10 mhz)
Most of the time, there was no audible difference between the clocks. It was impossible to hear a difference on instrumental tracks or on male voices.
Only on some tracks with female voices, I could hear a very small difference of timbre on the voice of the singer, and the sound of the OCK-2 was very slightly smoother.
But I could not hear a difference on other tracks with female voices.
To confirm my conclusions, I submitted Mrs. Dandoudou to a blind test. It was an A/B comparison between the clocks, with 5 tracks of different female singers.
She said that the sound of the two clocks was the same. On two tracks, she preferred the OCK-2 and said the voice of the singer was slightly smoother. On one track, she said that the sound with the OCK-1 was better.
Yesterday,
@roberto2 and me compared the clocks on his system that is as following :
- EtherRegen (+10 mhz) > SoTM streamer > Di-20 HE (+10 mhz) > Terminator Plus
We played a few tracks, and could not notice a difference in sound between the clocks.
Following these experiences, I can say that OCK-1 owners have no reason to upgrade to OCK-2, unless they need more outputs.
