I did a small test (€) today:
The configuration (based on Cisco Meraki Go 8 Port Switch (GS110-8-HW-EU):
1 X Mini Unmanaged 1x 10/100/1000Base-T RJ45 to 1x 1000Base-X SFP Slot Gigabit Ethernet Media Converter, European Plug standard - € 34,51
2 X Cisco GLC-SX-MM Compatible 1000BASE-SX SFP 850nm 550m DOM Duplex LC MMF Transceiver Module - € 16,66
1 X 1m (3ft) LC UPC to LC UPC Duplex OM2 Multimode PVC (OFNR) 2.0mm Fiber Optic Patch Cable - € 5,59
In total = € 56,76
Did it bring SQ improvement? Yes - a more clear soundstage. Was it a big improvement? No, a small one - nice but small.
Will do some more testing this WE on this little cheap solution.
Have a nice WE
EDIT: Test setup
Hi Torben are you running this to your endpoint and then connecting that to the media converter on Ethernet?
I always like try tests, both objective and subjective (it’s the tinkerer in me).
By using a mediaconverter and wallwart, there i a new distortion kid in town
Thanks Torben that’s exactly what I was thinking
Great that it’s working out for you, even if only a small uptick in performance.
It’s something that I keep thinking about and then remember that I am trying to simplify my living room setup
And a cheap test The “optimal solution” is more expensive:
Sonore Optical Module Deluxe II (OMD) copper to fiber [RJ45 to SFP vv] € 490.76
Power supply - SGC 7v LPS Power Supply and Regular DC Cable (220V) € 199.00
systemOptique Certified SFP module (2) € 41,90
systemOptique Certified Fiber Optic Cable € 20,95
Subtotal € 752,61
Subtotal incl. taxes € 895,61
I am not sure I want to spend that money. Time will show
Ah yes, a cheap test is good a test for something like this.
I have all the gear to test this unused in the office (besides the Linn selekt ) and maybe when I can send the wife away for a couple of days then I will have a play.
And another option to try is a better power supply for the FMC box…I have these in my network setup too, but with UniFi. The FMC is from FS.com for those that are interested.
@wizardofoz - what power supply are you using for the FMC box?
This. Powering the FMC and my Lumin D1. The FMC can be run from 5-12VDC
I’ve also used the Jay’s Audio/LHY LMPS or HDPlex LMPS’s
Hi @Torben_Rick ,
Happy to see that you adopted the option that I advised to you in the thread that was closed.
Power the media converter with a LPS, and you’ll get an additional improvement.
Yes that would be a good idea. But, not sure I will go with LPS. Right now I am looking at SOtM sPS-500 - that would give me the option of 7Vdc, 9Vdc, 12Vdc, 19Vdc selectable output voltage. That way I would be flexibel, if I want to use the power supply for something else.
Could you try the Cisco switch attached to the Linn end? I guess you would need another switch. The Cisco might be better than the FMC.
Have done different test - different SFP’s and cable. This is my favorite setup:
