Hey guys, I think that maybe some of you are confusing audible noise with the type of noise that masks? Covers? Hides? Muttles? Etc the sound of your music/sound system. A noise that beats down the perfect midbass or pitch perfect high note. We are not speaking of an audible hiss or buzz or what have you. Those are nasty but are much easier to identify. When you add something like a Schiit EITR and a tone becomes more refined, was that worth the price? If its audible and you like it better, yes. Did it clear up a hum or buzz? No but it ridded some type of “noise”. If your satisfied with your system, GREAT! Your done! 👏👏👏 If, like some folfs, theres that last little bit thats driving you crazy, the journey continues. At this time my system is in a state of flux and Im learning and refining my ears. Im having fun! 👍 Brooklyn; Burn time = 58 hours Nick you are so right...however I did know the reference when using the word "noise". That is why I said my system/music nirvana is sublime, pristine....meaning clear... In addition my equipment is dead quiet. Understand your clearing things up. |

When I use the word "noise" I mean the noise floor of the system. How quiet are the spaces between tracks, and between notes in a track. The S/N ratio of the system. USB S/N is notoriously low. USB to S/PDIF converters like the Eitr increase the USB signal's S/N noticeably. So too can good quality linear power supplies VS some switching supplies. Try it and see for yourself.

Has anybody measured there noise floor with REW?

So glad you’re thrilled with your system my friend! Sure wish I could borrow your DAC for a few weeks! 😁🎶 My system has no audible sound when not playing anything, I can put my ear against any driver at maximum volume and not hear a thing. Just wanted to make sure that you understood what noise Im speaking of. Im sure you do but others may not. Ive been unexposed to information like this some time ago. Theres still plenty I have to learn yet! Enjoy the music my friend! Sure wish it wasn’t such a long trip to visit! But I will one day. |

Has anybody measured there noise floor with REW? I can’t figure REW out! I keep stepping on the numbers!  Seriously, I still need time and patience to learn how to use REW. |

Theres still plenty I have to learn yet! Enjoy the music my friend! Sure wish it wasn’t such a long trip to visit! But I will one day. My you had every right to make the disctinctiom. When I was writing my comment thinking of "NOISE" you are right that immediately I thought of a "hiss or hum", continuing writing what you meant came into focus. Also Nick if you lived anywhere in the Philadelphia or surrounding area I would have no problem lending you the AUDIONOTE for a few days....even though I would be gritting my TEETH!😂😂😂 I have found that introducing new pieces into the system whether it would be in the HT or 2channel that sometimes a hiss in the tweeter develops or THAT HUM! I don't know which is worse but they are both annoying. With my latest investment of the SP14, Audionote, Mac Mini, and Monitor used in my 2channel I had a hiss coming from both tweeters. Long story short I had invested in a manual fault line protector from Home Depot getting rid of my Furman Elite. To eliminate the hiss I went to use my last line fault protector plugging my Mac Mini into it whereby the hiss was eliminated. The hiss had progressively gotten worse as time went on from first installation. I honestly do not understand that asepect. From not hearing anything to a slowly increasing "hiss" to being able to hear it seating in the sweet spot position. Now my system is hiss free..total silence when nothing is playing. Stay well Nick. |

Sorry, but all of that is just an old fairy tale. You are right. Putting a USB to Spdif converter in the chain always adds to sound quality. LOL Keep dreaming. XMOS xCORE USB Audio 2.0 is capable to output bit-perfect directly to I 2S without going through S/PDIF. www.xmos.com/news/videos/17674 |

Not necessarily. IMO, the kinds of noise floor matters discussed here wouldn't even register on REW, which has value in identifying large scale room mode issues, not fine grade noise. And, as subjective "opinions", measurements don't matter much, let alone need validation. Sounds great or not. Art or science, you decide. Massage or trip to the dentist's drill, both are useful, but somehow feel different. |

I wouldn't wait for an Emotiva solution. They have had one on the drawing boards since the XDA-1 days. Dan has said many times to just use a Mac Mini or RPi. Or any Windows PC running TuneBlade and a Apple AirPort Express. |

I just received a loaned MicroRendu with an Ultracap LPS-1 power supply (thanks sahmen for the loan!). I'm going to test it as a Roon endpoint (using the 14 day Roon trial period). So far, my first impression was that, despite knowing the dimensions of the MicroRendu, it's still a shock to see how tiny it is relative to the LPS-1 power supply. Other than that, it was easy to set up. Roon was easy to install and right now it's going through my catalog - nearly done so I will be listening soon. I will likely create a review thread on it at some point. Mark |

For the Elac, just the generic one that came with the unit. For the Sonore, their custom linear P/S. I also tried the iFi linear and didn't notice any real difference. Curious about the power supply comment...you said with the Sonore Ultrarendu you didn't notice a difference between the iFi linear and "their custom linear P/S". When you say "their custom linear p/s" - which one do you mean? And, thinking of the difference between your Microrendu and the Ultrarendu...how big was the difference for you? And, for the Elac vs. the Ultrarendu - and important differences for you? Mark |

And, for the Elac vs. the Ultrarendu - and important differences for you? Mark It's a linear P/S built by Andrew at Small Green Computer. A liner they designed for the Rendu series of products. If they are not on the SGC web site, email them. They cost $140. The Ultracap is likely superior to it. The difference between the UR and the MR was noticeable, but not earth shattering. Much quieter and more "punchy" which generally means better transient response. And by the way the UR is the same size as the Ultracap P/S. I am looking now into experimenting with a liner for the Elac. They shipped a 24 watt at 12VDC switcher from Ktec with it. I think I have a suitable transformer and rectifier in the garage so I'll likely Frankenstein one together to see if there's any difference. |

I guess you didnt notice the LOL at the end. And how does your statement contribute to the OP's question??? I did see the LOL, but what I didn't see is how your old fairy tale contributes to the OP's question. My suggestion regarding audiophile network players is to just avoid them exactly BECAUSE they're typically marketed around that same old fairy tale, when the reality is that they are first and foremost just a convenience thing, which is the complete opposite of spending your money more towards actual quality of the sound. |
