  1. I used to use this filter before I got my ER. I put it aside since it didn’t make sense to me anymore. based on the feedback here on the DX filter I think I will add it back before my optical module deluxe which sends single mode fiber to my ER, see if it makes any difference (I’m skeptical...)
  2. Thanks @JohnSwenson I will check that with the manufacturer of my device (miniDSP shd studio) would I be wrong to assume that most devices are most probably designed with the rca shells grounded? that said, if the RCA shell is indeed connected to circuit ground wouldn’t connecting this rca to another component which already has a ground (say like a preamp or DAC) provide the needed ground? Or is it better to provide this ground earlier in the chain before the leakage passes through the components? many many thanks for your knowledge and dedication!
  3. @JohnSwenson would connecting to ground the outer ring of an unused rca/bnc socket on a device that is powered by a smps have the same effect or is it essential to add the ground directly to the DC cable? many thanks. @Superdad would you consider selling smps with the internal ground shunt with other voltages other then your standard 7.5v? or can you advise where such smps can be obtained?
  4. Thanks John! I am not experienced in reading Jitter measurements, but all I have seen provide DB Vs frequency as an indication of Jitter or lack of it How does it relate to the time domain? here is an example, does this show Jitter performance better than 1ns?
  5. If I got it right, a better clock in general means less jitter. The thing that has me a bit confused is that I also understood that there is a thing called jitter rejection on the DAC - which I’m not quite sure I understand what it means - maybe it means the DAC is performing a reclocking process at its input? So if I have a DAC that has been shown with measurements that it has near perfect jitter rejection would I ever benefit from a better clock up stream? I’m not saying measurements are the only thing that matters, but if I should still expect to hear a different/better sound with
  6. Has anyone tried sfp modules from RME? https://www.rme-audio.de/sfp-module.html since RME are well known for high quality audio equipment (pro and consumer), I wonder if they sourced this sfp (I don’t assume they actually developed it) as best performance/sound.
  7. Thanks @One and a half, I had a look at Amazon and got lost. there is indeed no info on what the filters actually do. But then, I also don’t know what exactly needs filtering as I have no way to measure it. so a general filter would be a good suggestion. I was wondering if this would be a good choice (20A is more then enough) Noise Suppressor Power EMI Filter Termianl Single-Phase Line-Conditioner JREle AC 115/250V 20A JRW1220-22 https://www.amazon.com/dp/B073RMLFRC/ref=cm_sw_r_cp_api_glt_fabc_2EA1V7C48QNBKG45EWF2
  8. It's getting warmer and warmer where I live and we started using the air conditioner, Funny thing is that earlier this year I bought out of curiosity the PS Audio noise harvester, Didn't expect much of it and it actually did not show noticeable improvement to the sound. It didn't light up very frequently either, so I concluded that either it is just not doing anything or I am really lucky to have very clean power to begin with (I am running a dedicated line to my HiFi) BUT Now that we turned on the air conditioner it started flashing like crazy :-) I have
  9. No one suggested that the network switch in this box is equivalent to the ER, It is a switch (of some sort and quality) + OXCO + SFP + LPS,
  10. I don't think anyone would argue with you that room acoustics are one of the most important ingredients in the quest, but it is not the subject of this thread of the forum :-) I use the ER to feed a MiniDSP SHD studio which runs DRC (digital room correction) which takes care of some of the acoustical issues in my room.
  11. Though the description is a bit confusing, maybe the bellow @AfterDark. product is a worthy comparison to the phoenix, It seems to be an OCXO controlled switch, with SFP option and powered by an internal LPS + has an OCXO out, So, it's an all in one like the phoenix but with more functionality? (SFP, OCXO clock out) Not affiliated with Afterdark - just my thoughts here https://www.adark.co/collections/project-giesemann-ocxo/products/afterdark-project-clayx-giesemann-network-switch-x-ocxo-10m-master-clock-audiophilestyle-edition?variant=32208640540790
  12. Ok, maybe. I was under the impression there is a single OCXO in the box which provides a synced signal to 3 outputs (isolated or not) Perhaps @AfterDark. can clarify.
  13. I think isolation and sync are 2 separate things. Isolation is for keeping devices isolated from each other’s noise. Sync is to have both device synced to the exact same clock signal. as long as the devices are well designed and use quality PS (which is the case for Martin) the benefit of synced clocks is far greater then perhaps some noise leakage. at least this is my understanding
