Hi. I am new to the forums. I tried searching for this specific topic but could not find anything.
I have a Schiit Lyr tube headphone amp fed by a Schiit Modi Multibit DAC fed by a Sony DVD/CD player. A pair of Sennheiser HD800 HPs used to listen. For power I use an SL Waber wave tracker noise reducer/surge protector.
The power in my house is fairly dirty, making my old amp (Schiit Jotunheim) HD800 combo painful to listen to. It would get worse when the dryer or AC was on, or the lamp in my room was on.
This all started when I got the Lyr and Waber around the same time. The Waber actually does a great job eliminating noise and it no longer hurts my ears to listen. BUT, for some odd reason, the sound quality after 5pm seems compromised. Specifically everything gets less dynamic, leading edges on notes are dulled and the top end in general just seems blurred over. The bass also gets muddier and the soundatage fuzzy with a lack of depth.
I figured since most people get home from work around that time, the power grid is much busier? I am not very well versed in audio terminology but maybe it is DC offset occuring?
Anyway, my question is, would the CMX-2 be the right solution for this, or a UPS (uninterruptable power supply)?

What you want is power filtering. The CMX-2 should be the right product for the job - our customers report better results with the CMX-2 than with some pricier "audiophile" power conditioners.
An uninterruptible power supply contains switching electronics that would likely add noise to the power output, if anything. Normally they are designed to supply power to computers which also use fairly noisy switching supplies (not like the ones we use, which are adapted to audio applications through improved filtering, etc.) and those things don't care how much noise is on the incoming power line.
Do you have an exceptionally stressful or fatiguing job? Those things can also diminish your enjoyment of listening, and that might manifest as the colorations your are noticing. This is similar to what happens to your hearing after a few drinks - things become subjectively softer and fuzzier, and I suppose this is because the brain isn't reacting as quickly to the impulses from your ears.

Thanks. No, my job is pretty easy and stress free. Its not that. Also, I did not notice this until I got the Waber and Lyr. |

Have you tried listening with the Lyr but not the Waber in the system, then vice versa, then taking both out to see what sort of differences you hear? |

But removing the Waber isn't an option right now, because of the dirty power in my house. The sound makes my ears hurt. I need something that will deal with both the sound change after 5pm and the dirty power. It sounds like the CMX-2 is what I need. |

How about on weekends - do you notice any sound change on weekends? Might as well try a CMX-2 and see if it helps. |

Same difference (mostly), except with the CMX2 you don't need to deal with an extra component in your rack, and I can't speak to whether the Furman power conditioners are using any more or less or different filtering than we use. They carry out the same function, in principle. If you need more outlets, or if you need something that will mount in a 19" PA rack, the Furman line conditioner is definitely an option. Otherwise I'd look at the CMX-2 or maybe the CMX-6. There are some more high-zoot Furman products that are intended for home theater, but they cost a lot more - not just a little more. |

I counted 12 outlets that I use. Even if it were just a fancy outlet I would purchase the unit plus it has two adjustable lights that aid in seeing

Which Furman are we talking?
Also, can you plug a power strip into a CMX-2?

If it's really that noticeable then I'd suggest getting your power checked by a power monitoring company. It's pretty simple, they just come out and plug a monitor into an electrical outlet which records any fluctuations, voltage, RFI, frequency and things like DC in the AC. They usually leave it connected for a week or so and then come back, download the data and analyse it. That will confirm exactly what the issue is and help identify what needs to be done to correct it. I don't know about the US but in Australia we have standards (ASA 60038) for the quality of domestic electricity supply and if we get anything outside that standard the electricity supplier has to rectify it. Issues could be internal, within your house wiring and/or external in the grid that supplies the electricity to your house. Some electricity suppliers here offer a monitoring service to their customers, so that may be the first place to start.
Throwing a band aid (a power conditioner) over the sore (poor quality power) is not always the best solution.
Cheers

Just get a dedicated clock for that room and set it back 3 hours. That should provide an artificial time window for clean listening. |
