Would this work well going into active monitors direct from the gungnir?

To be clear, the preamp goes in between the Gungnir and the active monitors. (Seems obvious, but the question is a bit ambiguous.) 

 

If your monitors have balanced inputs, then get the balanced version and use the Gungnir's balanced outputs.

 

If your monitors only have RCA inputs, then get the unbalanced version, using the Gungnir's RCA outputs.

 

Don't try to go from balanced to unbalanced or vice versa with a passive preamp. Should work great!

Thanks.  I'm considering that xlr passive pre over the mjolnir, given the latter may color the sound.  

 

Any recommendations for decent XLR interconnects that would offer an improvement over monoprice?  I'm looking at spending no more than aprox. $200 on XLR pairs. Something on the neutral/musical side given i have active studio monitors.  i dont want to make the system sound brighter than it is.

 

 I'm planning on buying the audioquest coffee or the mapleshade clear plus for my USB cable.

Ever try Blue Jeans Cable? I have no experience with XLRs since my system isn't balanced, but they made me a beauty of a RCA to 3.5mm that I use to connect my Gungnir to my Pico Slim (seems odd maybe, but my headphone of choice is actually a pair of IEMs).

I wouldn't buy the mjolnir with the intent of using it as a balanced passive pre, it's primary job is to be a kickass headphone amplifier first, the fact it has balanced pre-outs is a bonus. It uses a high quality pot so I don't think you'd notice much difference. Just my two cents.

Instead of using a preamp - especially a 'passive' one, try the iFi iDSD. I have not listened to the headphone output. From what I have heard from the line outs its nothings short of fantastic. --- I'm loving this new trend in digital - I call it the DAC du jour. Very inexpensive and great for experimenting and mix and match. Its a no brainer at less than $200...

mind posting a pic of your gungnir/pico rig? Also thinking about getting a desktop dac for my earphones xp

Heh, it started out as a pursuit for a black background on my music. And I don't take my expensive toys on the go, nor do I listen to music on the go or during frequent activity. Shared living spaces mean no speakers, and open headphones aren't much more private. I don't like people hearing my music anymore than they like to hear it. So, I settled on earphones and worked my way up to the ES5s.

 

 

 

Someday I'll get a balanced amp (Mjolnir most likely) and nice set of Audeze or Senns. Then the desktop DAC will make more sense.

Does the Gungnir need the 5v from the USB cable? The question was asked before, but i cannot find the answer...

 

Someone using the Gungnir without 5V line? Improvements?

post #1360 of 1546

No the Gungnir has its own power supply.

Unless someone has tested otherwise, I'm almost positive that Schiit's USB card is powered via USB, which is why it doesn't disconnect from your computer if you turn your DAC off.

post #1362 of 1546

This is true. I just did the test. The USB card is powered by your computer. Not good in my opinion but it sill sounds better than my optical cable. I would like to get a computer with coax out. There are a few motherboard out there that have one.

What's wrong with that? It seems like the ideal way to do it since:

1) You don't have to worry about it connecting/disconnecting from your computer.

2) The USB portion likely draws very little power and is just doing digital -> digital, so quality shouldn't be dependent on the power quality coming from USB.

EDITED 2014/04/10 - After further investigation, I can only reproduce the proble with Gungnir + Foobar. I could not reproduce the problem with 2 other USB Audio devices + Foobar. I could not reproduce the problem using Gungnir + MusicBee. As such, I think it's only 50/50 as to who is really at fault. Added more detail below, but leaving this post here since the only other posts I see on the Gen 2 USB claim that everything is working flawlessly with WASAPI(Event).

 

Hi all, just received my Schiit stack including a Gungnir w/ USB Gen 2 today and I've noticed a recurring problem. Every time I start up a USB audio stream there's either a few very noticeable crackles/pops or a stutter in the first 3 seconds or so. Can easily be reproduced by simply pressing pause then play or pressing play when music is already playing. Has anyone else experienced this?

 

The problem seems to appear when I combine Foobar + Gungnir. I can't reproduce the problem when using MusicBee or other USB Audio devices. I'm almost positive that the source is somewhere between the Gungnir drivers and the Gungnir's USB inputs. I don't think it's the Mjolnir, cabling, or anything else, because it does not appear to happen with the Gungnir via Optical or with any other gear using the same cabling.

 

Here's my whole setup which should hopefully be enough information to diagnose/confirm the issue.

 

This setup reliably makes several snap/crackle/pops in the 1.5-2s after music starts flowing about 90% of the time:

PC->Schiit USB(WASAPI Event)->USB->Gungnir->SE cables->Mjolnir->Audeze stock balanced cables->Audeze LCD-3

 

This setup reliably makes several snap/crackle/pops in the 1.5-2s after music starts flowing about 10% of the time:

PC->Schiit USB(WASAPI Push)->USB->Gungnir->SE cables->Mjolnir->Audeze stock balanced cables->Audeze LCD-3

 

This setup occasionally makes the noises snap/crackle/pops in the 1.5-2s after music starts flowing < 5% of the time, but it will happen:

PC->Schiit USB(ASIO)->USB->Gungnir->SE cables->Mjolnir->Audeze stock balanced cables->Audeze LCD-3

 

All of the following reliably do NOT make a similar snap/crackle/pop:

PC->S/PDIF Pass-Through->Optical->Gungnir->SE cables->Mjolnir->Audeze stock balanced cables->Audeze LCD-3

PC->Tenor USB->USB->V800->SE cables->V200->Audeze stock unbalanced cables->Audeze LCD-3

PC->S/PDIF Pass-Through->Optical->V800->SE cables->V200->Audeze stock unbalanced cables->Audeze LCD-3

PC->SPDIF ALO(Pan Am) USB->USB->ALO Pan Am->Audeze stock unbalanced cables->Audeze LCD-3

 

PC is Windows 7 with an Asus Xonar DX running Foobar communicating via WASAPI(event) with a 5s buffer and basically nothing else going on (Core i7 with tons of spare CPU, so computer shouldn't be the problem). I tried buffers of 1s, 1.5s, and 5s, but it didn't seem to make a difference.

USB Cable is a random 6 ft USB cable that came with my V800 (Not sure this was even supposed to be in there, as I bought a demo model).

Also note that the "Buy better gear" light never came on at any time in this process.

 

I did go through all the FAQs and Troubleshooting steps in all of the following:

http://schiit.com/faq/usb-problems

http://schiit.com/faq/dac-problems

 

Gungnir is isolated to a USB controller by itself.

 

Due to lack of available desk space the Mjolnir is on top of Gungnir on top of an Onkyo Receiver (turned off) and next to a small bookshelf loudspeaker. I don't think this is related to placement, but I'll let someone chime in.

 

No power conditioning in this setup, but the computer is plugged into an APC UPS and all audio gear is plugged into a surge protector going into the same outlet. However, nothing except the 2 Schiit pieces are powered on atm.

I've been slogging my way through this thread (not entirely sure why I'd put myself through this) looking for similar issues and noticed someone mention a problem using WASAPI(event). I hadn't really considered that a possiblity, so I went ahead and tried the other output device types and tried my pause or restart test and I found:

  • With WASAPI(event): I can get the artifacts to happen 80-90% of the time.
  • With WASAPI(push): It goes down to maybe 10%
  • WIth ASIO for CMedia: I haven't heard it.

 

Also wanted to add that the sound I hear is NOT the relay click. I'm familiar with that noise already.
