You want a low impedance at HF, that's why a small value. The idea is to lower the power supply impedance at frequencies where the regulator has a high impedance.  Any time one uses a high slew rate opamp such as the Lm6172 or even the sensitive AD797, HF decoupling directly on the opamp pins is...

Try out LM6172 for I/V with MUSES01 in LPF and buffer. Solder 0.1uf stacked film caps between pins 4&8 (+&-) of the I/V opamps - try ebay for Siemens stacked film caps, you don't need large capacitance, just something to decouple at HF.     Class a bias could be worth exploring for heavy...

In that case, RMA it, either back to store or ASUS.

Thanks Chewy :)      You should not be getting any noise at all, aside from what Chewy suggested the only other thing I can think of is it may need a firmware update (you will need to connect it to a PC and download firmware from the ASUS product page).

Which input are you using?

I reported it to HQ but they have not been able to replicate thus far due to the random nature of the problem.

The DRAM instability may be due to using two separate kits. Likely need to adjust memory controller voltages and relax memory timings to cure that. Quote:

I am looping this to HQ. Can you please try the following:     Disable "SPDIF Passthrough Device" in the control panel Disable GX     Let me know if that helps. If it does not, then will likely need full config details including all relevant driver and software info.   -Raja

This post be SE pretty much sums up reactions of level-headed by-standers when it comes to audiophilia:   http://www.diyaudio.com/forums/everything-else/37842-one-way-make-expensive-speaker-cables-2.html#post437017

  Quote:   Using the DACs in mono mode can in theory provide better channel separation (SNR, crosstalk etc.).    In multi channel systems, you'd need enough DACs to drive each of the channels. Chances are each is being used in mono mode.  

There are two types of support a vendor can provide its customers. The first is reactive support where customer issues are addressed as they arise. Solely relying on reactive support methods does not pay long-term dividends in sharply contested markets. Online media and search engine...

Quote: Lets hope that does not include more post-test smoothing of the graphs...lol  

Quote: One would have to know the manufacturing costs of the drivers to assess the validity of that statement. If the graphs that Audeze ship with their cans hold any weight (and god knows they should if Audeze are using them), someone needs to match up drivers a lot better.    I...

Quote: So true Frank. It looks like the success Audeze enjoyed with the LCD-2 gave them the traction to guarantee a burst of sales with the LCD-3, and it is very possible that adequate investment has not been made in QC. I dare I say there may have been a slip in assurance policies...

Quote: I suppose it is swings and roundabouts. The high-end Sennheisers have very well matched drivers, which probably requires adequate levels of staffing, investment in equipment and time, as well as soaking up on yield drop-outs. 

I contacted ODU about buying some of these connectors who put me in contact with Sennheiser. Sennheiser replied after a while and asked me to contact my local Sennhesier office who WILL sell the connectors to me. I haven't enquired on a price yet, but I'd imagine it's a lot less than the $50 or...

Quote: Red blanket looks great! I think I'm going to ask Audeze to ship mine with a yellow one, though. :)   On a sidenote, yes, that shipping case should handle the bump and grind of frisky courier firms.

You can tame the highs of the HD800 a variety of ways. Depends how DIY oriented you are; a few signal path changes (tantalum resistors) will round off the edge definition enough to make most recordings very palatable (you can do this with SS gear too).

Quote: I know what you mean about deja vu, I got the same feeling when reading your impressions. I guess the LCD-2 have that effect?   Anyone see a pattern here? lol
