Schiit DACs (Bifrost and Gungnir down, one to go)? The information and anticipation thread. - Page 82

post #1216 of 3320

Drivers are software that interfaces a PC or mac to support a device that it is written for!

 

Firmware is the machine codes that operate whole pcb or programmable chips!

 

Yes, you may need external device and/or programs to load firmware.

 

Yes, firmware must be loaded in accordance to the steps outlined.  Otherwise like I said: expensive excercise.

 

Reason for firmware upgrades is to correct faults that were not detected during testing before production or faults that are reported by the end user that cannot be fixed through existing settings or replacement of hardware.  Drivers are also subjected to these senarios in which the versions are updated.

 

Not every driver/firmware update will fix issues 100% of the time, infact sometimes the updates can introduce different faults so be warned!!!  Like I said in some items you do not update unless it is vital to do so!!!

PC? Mac? I test software/firmware on real time systems with real time operating system. Have you written software in C language? Have you debugged code using a logic analyzer? Do you know what a bootstrap is? A bootloader? Do you you know how a compiler work? Have you burned eeprom? Have you ever written assembly code? Have you ever designed  software from a set of requirements? Been there than that.

Yes I have programmed chips in my college days 25yrs ago

Yes I have burnt ROMs and EPROMs,  this is what I do for a living

Cannot remember what a bootstrap is, or remember what a compiler is,  thats 25yrs ago

Haven't written software in C

Have written assembly code: again 25yrs ago

No, have not designed software for a set of requirements

 

Yes, I load driver into PCs and macs for a living this is to support the devices I maintain

Yes I upgrade firmware into $0.5M+ devices for a living,

Is there any other questions? Because basically I was just advising the difference between drivers and firmware!!!  Not being offensive or offending anyone and I do hope you accept my apologies if I have!!

I do not have brand name electronics apart from a mini max plus, because I cant solder devices this small,  all SS in my possession: I have built,  including speakers, This doesn't include Bluray player and a Stax Lamba!

 

 

 

Where Im from there are no more electronics engineering,  all this that you do are shifted overseas, by the way I do maintainance!!

With the Lyr/LCD-2s, no complaints. I find the individual notes and instruments easier to disentangle than with my old faithful DLIII. And the Schiit definitely pushes some sounds, like cymbals, farther out of the mix. Sounds that were in the background emerge more distinctly. On speakers, this sometimes verges on annoying. But then my Triangles are fairly assertive all on their own. Mostly, the result is hugely enjoyable - Joni Mitchell for example (No, I'm not a teenager.) Occasionally I feel there might be a little less bass, but it could just be that the bass is more taught. I characterize the Bifrost as lean and mean. And a heck of a bargain Some posters are asking for comparisons to other DACs. If anyone in the San Diego area would like to lend me their DAC, I'll see what I can do. And count me among those who can't wait to see the statement unit...

45longcolt,

 

thanks for the follow up, keep rolling in these write up!!

45longcolt,

 

if I was in San Diago I would loan you my EE mini max plus and my $69US Gigaworks dac.  But I'm 1/2 world away downunder to be exact!!!

Hey all,

 

To clarify: Bifrost has two sets of firmware--one for the main board and one for the USB board. 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 and run through a complete suite of instrument and listening tests--which we are in process with as we speak.

 

All the best,

Jason

Finally got my Bifrost today. Have just plugged it in and played a couple of songs. One thing that's pretty strange. Sometimes when click into different folders on my computer, the bifrost makes a loud click sound. 

 

Edit. Not only when browsing folders...  Really annoying!

I have the Schiit web page open right now looking at the Lyr with the mouse hovering over the buy button while I try to figure out which tubes.  My LCD-2 needs something more than the Asgard.  So another amp first.  Then DAC.  Tubes.  Which tubes.  This indecision is delaying my buying.  

 

edit:  And my previous comment was tongue in cheek even though I only put a sad smiley.  Just having some fun.


I've read a handfull of reviews that the LCD-2 isn't a bad pair with the Asgard. 6Moons said it was "Good", and I know there's a few people around who use the combination of the two without complaints. It's just not, you know, the best case scenario. Not everyone can afford the best case scenario though.

If you have the money buy the Lyr and have both that and the Asgard.
If you have rent to pay, I'd say give try giving the Asgard and the LCD-2 a second date, if you will.

And of course either of these will pair up well with the bifrost.

Bummer.  Welcome to the joys of computer audio.

Post in the "Computer Audio" section with info on your computer setup, hardware, and software.  Should be able to get that issue solved.  I doubt it is a Bifrost problem.

The Asgard isn't doing that bad.  It's just that the LCD2 isn't opening up as much as I've heard it do with some other setups.  It's an amp and source issue.  Which is a problem that a pile of additional Schiit gear might solve.  Possibly a Lyr as amp and Bifrost as source would do the magic for me?  That's why I'm watching this thread.  To see impressions of how the Bifrost gets along with the LCD2 and a Lyr.

post #1226 of 3320

The Asgard doesn't have enough power for the LCD-2 shine and treble for that matter.  The Lry with it's ample power and a slight treble emphasis will match the LCD-2 better. 

From what I hear, the Bifrost will I think match the LCD-2 too.  It seems to have a wide soundstage and a slight treble edge.

I gotta say I like the Lyr and LCD-2 so far. Im no reviewer but I can say generally speaking that with the Lyr the LCD hits harder, more punchy and tight sounding, kinda brighter though compared to the LCD-2 with my WA2. The WA2 has a warmer tubyer softer sound including the bass and voices. The Lyr is edgier, voices are sharper, and occasionally almost get shrill, but they never seem to hit that point the way Ive heard in the past with cheaper portable gear. In sum, I prefer using the LCD-2 with my Lyr over the WA2 due to the LCD already being warmish without enough sparkle. The Lyr gives it that sparkle without losing control at the top. Im using Mullard tubes in the Lyr though which also factors in. I use my WA2 with my Grados and the Beyer DT880 although they sound fine with the Lyr, I like with the WA2 more. They are smoother sounding with the WA2. Of course tubes play a big role in all this so if you get the Lyr you can tailor it the way you want with tubes, you really can.

 

When I get the Bifrost I can compare it with the MSII+ that I have here. But again, Im no reviewer so perhaps I should just keep a lid on it and continue listening and tapping my toes, which is what I do best hehe.

Jason,

 

is there a plan to get firmware for the main pcb to pesent Bitfrost owners?  And what does the firmware correct/improve? 

 

On this thread several owners of the Bifost dac have complained of clicking sounds when changing tracks or folders, are these issues being investigated?

But how could it be a computer issue when the sound/clicking is coming from the dac itself, not the speaker/headphone.

Ok, I see what you are saying, I didnt pick up on the fact it is physically making the noise and not electronically over the headphones. That would be really annoying. I hope this gets fixed if in fact there is an issue and it sounds like there is.
