Just ordered the SW-6 yesterday. Shazam, it’s been significantly updated to AS-6. Admirably, the updated device will be sent. (Beatechnik is linked with Vinshine, one lists US$ prices, the other Singapore dollars. Alvin Chee at the helm at both, a very good guy.)
This exemplifies my comment in another post, good products get updated.
I wonder if this is worth getting if I’m already using a Mutec Ref10 nano to drive my SW-6. The Mutec’s phase noise at 1 Hz and above is at least 30 dB better than what’s stated here.
The beefy noratel transformer looks nicer than what they used in the sw6, sw8 & sw10. Hopefully it’s a worthwhile improvement
Wondering what the improvements are.
Also the SW-10 sold out a while ago. I was hoping for a new one of those.
the SW-6 was sold out for a while too, and long delivery times
me thinks that this is because updates were in the works, which just happened for the SW-6 (to AS-6)
I was privileged to meet Alvin at Axpona. Super humble guy with lots of great looking hifi.
question for those who’ve done it
instead of a pricey ether to sfp/fiber converter to go with these LYW units, what disadvantage would a ‘cheapie’ about $50 have…especially in view of the tech in such audiophile switches?
No big deal in my opinion. I went fancy, no big deal. Start cheap.
Hmm. I wonder why he went with the bigger caps in the power supply section, rather than sticking with the smaller “supercapacitor”-like design?
Maybe due to the toroidal power supply? 
I started with the cheap fiber converter the FMC SW6 combo is far superior. The difference is not subtle imo.
not much, but the Finishar ones, and even pricier ones tend to not add or sbtract anything. The cheaper ones tend to change the sound, can be a bad flavor, I have one set that does that.
Have one to recommend?
Forgive me for linking ebay liquidations here, too cheap to call audiophile, but they are the same, these new on mouser cost, probably, forgot how much I paid, around 70 bucks a pop, cost to nothing on the liquidation market though:
multimode(normally grey jack fiber): FTLX8571D3BCL FINISAR SFP+SR/SW 10Gb/s 850nm MULTIMODE SFP+ TRANSCEIVER | eBay
Single mode(normally yellow jacket fiber):
If you want new just writedown the part# and search on sites like Mouser. They’ll probably be a slightly different model since sites like mouser tend to have the most current stuffs. As long as you stick to big brands you should be good to go.
somehow, wires are crossed
I was asking about the less expensive ether-optical converter ‘black boxes’, not the cables or SFPs (specifically the LHY FMC (and by extension Tempus etc) vs the Starlink/Finisar/many other units)
It must be that the SFP electronics doing the conversion (ethernet cable data converted to light) can be accurate or ‘not so much’ AND all the electronics in the ‘black box receiver’ of SFP output, far greater in size/number of components, do well or not.
I am especially interested on what FMCs, the box, do with all the components after its gets the light from the SFP and before outputting RJ45 to go to the network switch.

$61 vs hundreds/thousands
Many, myself included, have used MCs with after market power supplies to good effect in our systems. I have a pair of TPLink Media Converters and a pair of iFi wall wart power supplies ferrying the data stream from my eero Wi-Fi Mesh base station to my EtherRegen. No night and day improvements have been noted, but its an economical way to isolate your endpoints from any upstream noise that may have been riding on the local area network connections.
Some good info. about the approach and related options in this thread:
IFi power supply products might be of interest to you:
Have fun.
Can’t really help there, I went with a full stack Unifi gateway and switch route.
