  1. Well, I saw the influence of Ethernet cables was already shortly discussed, so I thought why not drop the other bomb... 😉 For now I’m anxiously waiting for delivery of my ER with stock supply from Joel with Metawave, but of course curious if I would be missing out on a further SQ upgrade when using the stock supply.
  2. Anyone who has experimented with different power supplies on the ER yet? Maybe one of the beta testers?
  3. @Superdad: could you please share if during your tests the standard and upgraded power supply for your ER were connected to the same power distributor as the power cables of your other components, such as the DAC and the power amp? The reason I ask is that even if the quality of the power supply would not influence the performance of the ER, the standard SMPS brick might 'contaminate' the power for other components if connected to the same power distributor.
  4. @sockpit: I haven't purchased the subs yet, so no hum (yet). Mainly interested in isolating the sub that can't be connected to the power strip based on the findings in this topic:
  5. I'm considering buying one or two REL subwoofers for use in my 2-channel system. I have a class AB amp. REL advices to place the subs in the corners on the room for best SQ. Assuming this is correct, in my system this means at least one of the subs can't be connected to the same power strip as the other hifi components. As most of you will be aware, RELs preferred connection of its subs to a Class A/B amplifier is not with RCA or XLR cables, but with a cable that has a Speakon connection on the subwoofer end and three bare speaker wires (or spades) on the amplifier end, see: https://www.youtube.com/watch?v=YIenhBQEtE4 When connecting subwoofers to the amp through RCA interconnects, products like the Jensen IsoMax or Blue Jeans Cable subwoofer isolation transformer can isolate the subwoofers from the rest of the system, if I understand correctly. My question is if a similar solution exists for the REL speakon cables. Thanks in advance for your answers.
  6. To add to the post of @matthias,Taiko Audio prefer Startech SFP modules over Finisar and FS store for audio and 1GB SFP over 10GB SFP, see post #920 on: https://www.whatsbestforum.com/threads/taiko-audio-sgm-extreme-the-crème-de-la-crème.27433/page-46. For implementing 10GB SFP in a home network for hifi purposes, the QNAP QSW-308S switch ( https://www.qnap.com/en/product/qsw-308s) mentioned later on in the thread might be an interesting product that seems relatively affordable.
  7. After reading the IT approach with an IT before the power strip and every component connected to the same power strip advocated by John Swenson in one of the first posts of this thread, I have the following question. Wouldn't using a separate IT per component and plugging these separate ITs in to the same power strip lead to the same advantage of cutting down impedance, lowering noise generated by leakage loops? If this is the case, the additional benefit of separate isolation would be that noise between components is also blocked. This seems to be the approach of German manufacturer Audioplan (https://www.audioplan.de/mainspower-en/powerstar-en/?lang=en), when you would ignore the filtering before the power strip. If my question is considered too off topic for this thread, feel free to remove my post.
  8. After the solid-state / SET debate, the discussion regarding electronic music is also getting a bit off-topic IMHO. So please open a new thread if you would like to further discuss on music types to evaluate HiFi.
  9. New Intona USB 2.0 Hi-Speed Isolator 5kV 7055 B released, time for a new comparison with the ISO Regen? Features of the new model include an LT3045, for details see: https://intona.eu/en/products/7055-b#features First review here: https://twitteringmachines.com/audiophile-tweaks-from-intona-technology-and-sonore/
  10. Hi @soares, I kindly refer to my post #16 in the Q&A topic elsewhere on this forum (see link below). For your situation I would either buy different transceivers and a different cable to work with the MC200L, or indeed buy a MC220, whatever is cheapest.
  11. @soares : I'm not an SFP specialist, but if I look at the specs of the TP Link MC200M it doesn't seem to accept 1310nm and is only compatible with 850nm, whereas the MC220L is compatible with both. My best guess is that's where the problem is.
  12. Thanks for all your in-depth reactions so far, much appreciated. Following the advice of @fas42 , I did some experimenting with plugging components in the PS Audio Dectet and in a regular Brennenstuhl power strip. Note this was not a blind test, so some bias could play a role. Furthermore, in my living room only one wall socket is earthed, creating an additional variable. The outcome of the experiment was: - integrated amp better without power conditioning - DAC: indifferent - server/streamer: better with power conditioning - switch: better with power conditioning I intend to try out listening to the system plugged into a quality, non conditioned, power strip over a longer period of time. Later on I might do some further experimenting with specific measures for the server/streamer and the switch. Interesting that @PeterSt and @monteverdi mentioned the fridge. The build-in fridge in my kitchen also creates some problems in my system; as the fridge turns on, sometimes a short tick can be heard over my loudspeakers. The separate power line for my hifi system didn't change this. I also tried to tackle this with an Essential Audio Tools Pulse Protector in the wall socket closest to the fridge, and while this does help a bit, the tick is still not completely gone. So I too have been thinking about buying a new fridge...
  13. @soares : the SFP port of the Cisco is gigabit so should work with a gigabit SFP port of a TP Link, as long as compatible transceivers are used. I have the SFP port of the Cisco connected to the gigabit SFP port of a TP Link MC 220. The 8 regular ethernet ports of the Cisco are 10/100. To be complete there is also one gigabit ethernet port next to the SFP port.
  14. Over the last couple of weeks I've been reading up on power conditioning, as this seems an area in which I can improve my system. I'm now using a PS Audio Dectet I bought years ago on a separate power line with all audio components (including amplifier) plugged into it. It appears there are several approaches when it comes to power conditioning (e.g. isolation transformers, balanced power, power regenerators, active filtering, passive filtering; also amplifier and other audio components on the same power source vs. separate power source for amp and for components), but with every approach comes the caveat one should try it at home in his/her hifi system before buying, as every situation differs and there seem to be no absolutes in this area. Within each approach one further has the choice between different brands and models of course. This brings me to the question if people have compared say three or more approaches for power conditioning in their system before choosing and buying their final solution. I would appreciate it if you could share how you came to your decision on what power conditioning works best for your hifi system. Thanks for your input.
  15. The exact description of the transceivers is: Cisco GLC-LH-SM Compatible 1000BASE-LX/LH SFP 1310nm 10km Transceiver Module. Cost was EUR 6 per transceiver. The cable is: LC-LC OS2 Singlemode Fiber Patch Cable. The transceivers and the cable were ordered together at the same webshop. Hope this helps.
