Annoying Yiggy Issue

[krelldog]

I love my Yiggy except for this issue.

If I turn on or switch fan speeds on my ceiling fan...it terminates my connection from my Mac Mini to my Yiggy.

 

With that said-all of my components are plugged into a PS Audio P-10...and the P-10 is plugged into a dedicated outlet on its own 20 amp circuit.

The ceiling fan switch is also a fan switch like its supposed to be.

 

Any ideas???  Its not an issue during cold months....but a big issue during summer time.

[Dr Tone]

Does the problem exist without the P-10?

Does the problem exist with a different computer driving the Yggy?

Have you tried a different USB port on the Mac Mini?

[krelldog]

Good questions....I'll check it out.

[krelldog]

BTW...I also have an Uptone Regen and the 1.2 power supply in the chain also ...

[davide256]

Are you able to change speeds using the typical chain pull, if so does that cause same symptom?

 

Unlikely that switch is at fault, the fact that gear is on separate circuit but  has problem sounds more like RFI caused interference

from fan motor.

[krelldog]

No chain pull...Its a newer Hunter Ceiling Fan with a newer fan switch.

 

If its RFI...what can I do to stop it from happening ?

I have a similar setup. Occasionally the Uptone will drop. On my Yggy the sample rate lights will turn off but the power and input lights stay on. It happens so seldom I've yet to trouble shoot it.

I'd start by removing it and then continue on my list.

Not sure the issue is RFI,  more as the fan turns on or off a large voltage spike is created. This spike may be induced with the fan cable being close to the power supply cable for the p10. 

 

Fan motors are only small and shouldn't pose such a problem,  perhaps the switch is wearing out due to fatigue and arcing unnecessarily.

[davide256]

Start by simplifying the chain, connect USB source directly to Yggy, see if problem goes away. If still present, try a different USB cable, the shortest you have. If either

step works, you know the interference issue is up stream from the Yggy. Worry later about whether its RFI or a voltage spike somehow making it through your P-10,

whats important now is to isolate at what point in your source to DAC solution the problem is introduced.

+1 this the way to approach the problem.

I took the Uptone Regen out of the loop....Now its fine....no interruption.

Not sure how old your Yggy is, but if it it has the Gen 5 USB implementation, external "decrapifiers" are redundant - worse really as they are another point of failure.

[AnotherSpin]

Just by coincidence I removed Uptone regen today from USB connection from mac mini to my new Gungnir Multibit with Gen 5 USB. Only to check how it will sound without regen which I used always with couple of previous DACs for several years. Had no loosing signal problems.

 

While regen was giving certain improvement with other DACs, Gungnir works clearly better without it. It looks Gen 5 USB provides what was promised. The sound is "cleaner", better defined, gives more impact and emotion.

 

I would encourage anyone who uses any of Schiit DACs with Gen 5 USB to try and compare USB connection with and without regen or other USB "decrapifier".

Want to sell the Regen cheap?  Or does it come with a guarantee?

[Ishmael Slapowitz]

Hmmm Very interesting issue. Will be following....

I would be curious if the problem returns if you put in a hub powered USB "purifier", like the Intona or the iFI.

[motberg]

I assume this is the ISORegen?

I had the same problem. With ISORegen in chain, switch the lights - music computer shuts down.

I gave the ISORegen to a friend.

Intona Industrial and the Singxer UIP-1 both work OK in my room.

I am currently using the Gustard U16 DDC and find this still benefits from the  UIP-1 followed by a W4S Recovery - all powered separately by either LPS-1.2 or LPS-1's followed by LT3045 DC-DC convertor boxes. Wonderful and consistent SQ...

 

That is great to hear Schiit is making progress with USB inputs, I have found similar results with the Audio-GD isolated Amanero USB.

I would sell, pm me if interested...)

Interesting. I have a Yiggy and a Mac Mini. This does not happen to me. Of course, my audio equipment is isolated from the house mains with a 30 Amp hospital isolation transformer/mains filter. That might be the reason.

 

My main problem, at the moment, with the Yiggy, is that after I heard one of my own orchestral recordings (Ravel’s “Daphnis et Chloe”, the complete ballet) played through a Chord Hugo 2, I no longer consider the Yiggy as anything better than a 2nd rate DAC!

In my opinion you rate the Yggy much too highly by calling it 2nd rate.  Maybe lower 3rd rate.  Worse if you consider the price they charge for it.  Repeat after me:  Don't DO SCHITT!

Something personal?

Well, it’s not THAT BAD! My Yiggy is certainly a decent DAC. For instance, I’ve never heard a Delta-Sigma DAC that could hold a candle to the Schiit Yggdrasil, and that includes the latest ESS SaberDAC Pro based units. It’s just that the Chord unit works on an entirely different principle with its 49000+ filter taps! CDs, digital files of all bit depths and sample rates resolve details, that I didn’t even know were there! This includes my own recordings which I know intimately, or at least I thought I did.

I appreciate your opinion. However, comparing Gungnir with Chord Mojo I came to rather opposite conclusions. Yes, I fully understand the difference between entry level and more advanced item from Chord. There is also certain difference between two Schiit DACs. Still I could guess there is some specific sound signatures within particular approach. To me Gungnir sounds much more natural, fatigue-free, "analogue". Resolution my impress immensely in a short run, but long run impact seem to be more important to me.
