Have you notice this on previous dac?  On my gigaworks dac I have notice this which is really annoying but it only happens to a sony s580 and not a s470.  But on my EE mini max plus this is not the issue for either bluray players!

I get the clicking also. It's rather loud.

My goal here, exactly. Looking forward to hearing impressions of this setup. Do you happen to have a LCD-2 r.1 or r.2, Ham Sandwich?

Just came from a Nuforce Udac, so I have very limited experience. I'm currently experiencing some issues with my mobos soundcard at the moment, so I'm actully not able to get any sound out of the soundcard. I have ordered a new one though, since I don't want to spend the whole weekend gooing through x forums to find a solution to what I think is a driver issue or something. Asus Xonar DX is on it's way :p 

 

I've just had the time to play a few tracks with my Bifrost connected  (to a different computer) and that was when I got the clicking sound. I can try to upload a video to youtube or something to so you guys can hear and see it by yourselves.

Hopefully Jason is looking into this and have a fix for you guys,  Im hoping a firmware upgrade into the main pcb is possible to correct this.  On my gigawork dac and s580 combo the click is like a thump when you turned a power amp on before the pre!!!  But in saying that the gigaworks dac was only $69US

Sounds a lot like some sort of relay that's tripped when you switch sample rates. While I'm curious to understand the cause, it's a non-issue for me. Btw, Bifrost landed. Burning in. Impressions to follow in a bit, but I have to say - very impressed so far. This is on my work rig (hires flacs, Decibel player, Bifrost (spdif), Lyr with Lorenz trimica's). I used to have a MSII+ (USB) in the chain.

I have the rev 2 version.

I knew the Asgard wasn't going to do it for me the way I want the LCD2 to sound.  I've been able to try the LCD2 in my setup at meets.   So I knew I'd be needing a new amp and very likely a new source as well.  For now I address the lack of openness with some EQ so I'm doing OK for now till I get the amp thing figured out.  The amp is very very very likely going to be a Lyr.

If it's a relay click, maybe the optical out or coax out from the computer is losing sync at times and forcing the Bifrost to reset.  Bummer if there's an audible relay click kicking in all the time.

 

I don't have a Bifrost (yet) so can't confirm.  Some troubleshooting steps would be:

Run DPC Latency Checker and LatencyMon to make sure your computer isn't doing huge latency spikes which might cause the audio to lose sync

Use WASAPI mode to bypass the DirectSound which may be forcing a sample rate change or unexpected sharing (mixing) of audio signals (assuming you're on Windows)

Use a media player like Foobar or J River Media Center that can do gapless playback and WASAPI

eco, you seem to be a little fixated on the firmware thing.  What Jason said was: 

 

"The USB boards that we received came with an earlier version of the firmware. We want to get you the latest, so we have to update them...."

 

Jason hasn't said anything about a firmware update for the main pcb as far as I can tell.
 

Now about this firmware updating thing: I've updated the firmware for my phone, my TV, my satellite receiver, my DVD/Blu-Ray player, my wireless router, and my internal SSD for my computer many times, with firmware updates made available to the public via download from the Internet.  Not a huge deal.  Yes, you can brick a device if you screw up (or if you are so very unlucky as to, for example, have the power go out in the middle of updating).  But considering the Bifrost's capabilities can be modified through downloadable files (such as USB 2.0 drivers for Windows), I'd actually be a bit surprised at this point if the Bifrost's firmware were not able to be modified in the same way.

I can say that when I had my QA350 hooked up to the Bifrost via Coax feeding only 16/44 wavs, no clicking ever noticed on my part.  Hopefully that helps diagnose the issue.  Good ole low rez wav files, hooray!  tongue_smile.gif

Hi Anaxilus,

 

      I'm particularly interested in that combination - did I miss your impressions earlier ?

 

Thanks,

I only get the click when I use it with my cd player in my signature. It doesn't happen when connected to pc.
post #1244 of 3320

Such clicks usually happen when the Data Stream is being interrupted. The DAC temporarily looses lock and the Data Stream must be reacquired. Some players stop the data stream between tracks (and some form of clicking can result), some PC configurations also can cause this issue. About 10 years ago I had a wicked expensive Krell processor that lost lock (and therefore clicked obnoxiously) between every track. It ended badly.

 

As far as the Asgard having enough power for the LCD2 goes, when I tried them together power wasn't the issue. I ultimately preferred my HiFiMan HE5LE to the LCD2's.

I hope that your're right, I'm hoping that Bifrost is the same as all the others where It can be downloaded via web and with specific instructions can be loaded onto the main pcb. 

 

On the devices I work on this is now not done with EEPROMS anymore, this is now done with files loaded onto an SD card.  Catastrophic if it is not done right!
