Anyone can pick either SM or MM and be happy with it. I don’t think there is a huge need to worry about it. I use both but rewired my house in SM because a duplex SM cable can handle speeds >100Gbe whereas with MM you get into these complex and very expensive cable assemblies. Anyone who is having fiber run through your walls, I highly recommend SM.

I have been using 10Gbe switches with 1Gbe endpoints since 2015 and have not encountered any that don’t work perfectly well. Not all SFP/SFP(+) modules work will all devices.

Right. Those active optical cables are cheap and when they work, they are great. The Mikrotik cable is expected to work on the Mikrotik end, but isn’t guaranteed to work with an arbitrary endpoint — in this case the aether REGEN. It’s an SFP(+) cable so there is no expectation that it works in the EtherREGEN SFP port! The fact that some SFP(+) modules work in some SFP ports is great but doesn’t mean that this will always work — and in this case it doesn’t. The safest way to connect a 10Gbe switch with a 1Gbe endpoint is either: 1) dual 10/1 SFP+) module on 10Gbe side

How many channels? 😂

Double ganging?

Great, this is a unique feature in a DSP engine! Precisely. @Miska regarding conversion of PCM to SDM via EC vs SDM convolutions, the convolutions are CUDA accelerated, right?

Right but USB4 is merged spec with TB3 so I’m hoping a USB4 (which M1 has) fiber cable will work ...

Not the thunderbolt optical ones. USB4 is merged with thunderbolt3 so I’m hoping that would be a true fiber USB cable — you need a powered destination

The new USB4/TB3 is what I’m thinking. The Corning is still at TB2 but awaiting update.

I haven't been keeping up with HQP on OS X recently, are there still driver issues which limit the bitrate? or other limitations. This would be HQP on OS X direct to DAC

I see that the M1 Mac Mini has USB4 so with an optical Thunderbolt3 cable, and a USB-C to USB-A converter with might have the holy grail of USB isolation ... that would make a very interesting NAA ... or maybe run HQP direct on the Mini?

Right ... the new Intel chips were overclocked to 8Ghz so I was suggesting that with a liquid nitrogen setup we could do DSD512 ... not practical.... So yeah maybe offline conversion ... ummm would love a reason to justify a Holo May ... uggh

Are you rewriting the algorithm 😆 I think with audiophile LN tanks we can get to DSD512. Do you think the tank connectors will affect SQ?

With HQPlayer that shouldn't happen too much. Typically I'm using Roon to feed HQPE (because I like the GUI/iPhone etc) and HQPE is setting the format and rate. Maybe if you are changing rate families...

Hmm I was compiling the RT patches for awhile for the clearfog and my NUC but frankly don't hear a difference, low-latency seems to work well. Dropouts only occur if I'm running heavy background tasks so frankly I got tired because its just easier to let apt update/upgrade.
