Network Switches
From what I can gather from the links to the 3 switches mentioned in the OP the sotm switch is not a managed switch but a basic level 2 switch so I can’t see anyone being able to manage changing packet rates. I haven’t found as much on the other 2...

New Joseph Audio Pulsar Graphene 2
Since they  are upgraded  to  the  standard  of the new version why would  they  sound better  than the new version?  
New Joseph Audio Pulsar Graphene 2
I have the upgraded Perspectives and they leave me pretty twinkly as well. I know the crossovers were either replaced or modified in some way and Jeff said they would be indistinguishable in sonics from the new ones. I am not good with the hyperbo...

Sorry to ask this SACD question, but
SACD players will play the disc through the internal dac  what they will not do is output the signal through the digital out to an external dac. Those that do have paid a fee in order to do it.

Nice to see this thread back on track. I bought a pair of used Perspectives and sent them to JA for the upgrade which he assured me would make them indistinguishable in sonics from the new version 2. I have been reading about these speakers on var...
