I didn't like them either. So I used a very small hole punch to cut tiny dots of colored electrical tape to stick over the led holes. It's subtle and much dimmer.

At this point I like the sound of the Bifrost with a blue light, and find the Valhalla's transient response and attack is quicker with a red one.

Pure awesomeness!

Some people are saying the uber increases the highs and some say it rounds them off. So which is it?

I find these boards really funny, when some one says "the highs are better" what does that mean? What does it mean to you? To me that means that the highs are smoother and easier to listen to, less offensive. But to someone else it means more treble, a more crisp sound, something I would not like. I think a lot of people assume that everyone thinks/hears like they do. It's simply not the case. I've owned some headphones that sounded great with some gear and not so good with other gear, so I don't really trust what anyone says about anything unless they are saying what the whole system is comprised of and how long they've had the stuff.

Quick question guys just to make sure before buying the uber upgrade.

Do you need the USB Gen 2 plug upgrade for the Uber upgrade to work or are they separate upgrades? I am only looking forward to upgrade the Uber actually.

Also I read something about driver problems previously in the thread, anyone else experienced this?

 

Thanks...

I also read about the highs being over the top but I dont hear it on my rig.

 

I have to agree with JM, unless everyone is listening to the same system opinions are going to vary, which makes it all a big guessing game. Also it can be hard to sift through the "flavor of the month" threads. LOL!

You do not need to purchase the USB upgrade they are seperate boards. I have had no driver issue with the Bifrost.

As I posted a while ago, I found worthwhile improvements in:

1. Dynamic swings (soft to loud).
2. Transparency across the board. One more dirty pane of glass removed.
3. Timbre and texture. Now with more uber hours on both the Stax rig and Valhalla/Grado, this "touch" factor is the most appreciated change of all.

Major frequency response changes? Nope, only a bit more solid bottom end.

I just got my Uber upgrade in the mail today. The installation went fairly smooth with a few notes:

 

It works great if you remove the metal chassis first, leaving the actual board attached to the aluminum cover with those middle bottom screws still in. This method is mentioned in one part of this thread. I then got under the DAC while keeping it level and removed those middle screws holding the board, so the board never got to move around. I got to looking and if someone had the entire thing tilted up and unscrewed the board completely, it would have fallen forward and I could see potential for the LEDs getting bent or other damage occurring. I also note that by removing the screws between the aluminum cover and chassis, there were some metal shavings around the holes. Some light debris ended up on corners of the board inside. If you have this, make sure you get that cleaned up, because a large enough shaving could cause damage in a worse case scenario, or who really wants metal scraps on their board? ha. I really wouldn't recommend someone that has never taken apart such devices to attempt this over sending it in to Schiit, not that it is difficult, but I could picture things going wrong. Not something to rush through either. Another small thing I had to do was bend one capacitor slightly out of the way of the screw hole, on the new board. I could not get the screw in unless I did so. Just make sure you are ESD safe and have good lighting if you do this. Get all of the screws relatively firm, but not overtightened. I had to do a very small amount of guiding to get the LEDs in the holes, just a slight tweak a couple times and they went in fine. Tape the button in place on the front before you even start, with some painter's tape, etc.

 

Here are my impressions of the upgrade with my setup. I use my Bifrost (SPDIF) with Asgard 1 and HD600s:

 

Well I had read all of the feedback on here, and of course I had no clue how much people were exaggerating about the differences, if any. I kept having doubts about making the purchase because it might not be worth the money and the trouble of taking the thing apart. I made a list of about 10 songs that I specifically listened to in a sequence, a couple times a day, for many days, at the exact same volumes each time. I felt this was maybe the best bet to hear the initial differences, since you can't just go back and forth between the new and old board. With this embedded in my head, I made my first listen:

 

I was very surprised of the differences in sound. I honestly had a large grin on my face for this first listening session. It's very obvious the first time, but I notice my brain adjusts to the new sound quickly after multiple listens. The best way I could describe it is everything is a bit clearer. It is as if another thin grainy film was taken away, same thing I experienced coming from no dedicated DAC to this Bifrost initially. There is something slightly different about treble overall. I can't fully describe it yet, but the best thing I can say is it just sounds cleaner, and slightly more textured/detailed. As some others had mentioned, there actually is some changes in the low end. It isn't that there is more boom, but rather it just sounds like it's more concentrated and somehow impacts harder. It isn't an enormous change, but is quite obvious right off hand. 

 

Overall I'm really happy with the upgrade. It was the best improvement I could make for such a small cost. It isn't "twice as good" of course, but it is pretty damn good for the money.

Thanks man for the confirmation. Goin' to upgrade in the near future perhaps.

For those of you with experience with the PS Audio DL III, how does the Uber Bifrost compare?  I ask because I currently use an HDP as a Dac but heard a friends DLIII and decided I should start looking to retire the HDP as a DAC but don't want to spend that kind of money.

Just installed my Uber card last night! Whole process took around 10 minutes, pretty quick and painless, and as everyone said, lining up the LEDs seem to be the most difficult part, and its not really that hard. Anyways, on to the sound quality.

 

I have the Uberfrost paired with my Lyr and Russian 6N1P NOS tubes from Schiit, driving HE500s. I originally had stock E88CC JJ tubes in my Lyr. I will review all the different combinations I've experienced.

 

Bifrost/Lyr E88CC

With the stock JJ E88CCs from Schiit paired with the regular Bifrost, I felt there was a sharp spike in the high end. There was good high end extension, but always just some notes that are a bit too piercing for my taste. The mids were smooth and very lush. Lows were really tight, very nicely textured and detailed. All in all very nice and flat, neutral sound, and a very good place to start and set the standard.

 

Bifrost/Lyr 6N1P

Rolling into the Russian 6N1P NOS from Schiit, the Lyr's piercing high end vanished, but so did the high extension. The bass gets extended deeper, and slightly harder hitting, yet maintaining its tightness. The bass is not over emphasized. Overall a warmer tone, and much more enjoyable sound, and less analytical.

 

Uberfrost/Lyr 6N1P

Finally, the Uber Upgrade. After dropping this card into the Bifrost, the first thing I noticed was transparency and the fine detailed texture across all frequencies has improved. You can hear the brushed metal grooves on the cymbals as the drum stick runs across it, the delicate rrrrolling of the Rs from Melody Gardot, and even seeing the sine waves from Lindsey Stirling's electric violin. The extended highs seem to be back, but without the frequency spike or harshness anymore. All in all, sound signature similar to the Bifrost/E88CC pairing, with a smoother high end, finer all around detail, and better transparency. 

 

Uberfrost/Lyr E88CC

More of the same from the original pairing of Bifrost/E88CC, but now with finer all around detail and transparency, but the highs were definitely too... shiny? Harsh? Sibilant? Too bright? A little reminiscent of my good ol' hotrodded X-Fi with max crystalizer (V-shaped EQ). Dunno, didn't spend too much time here and went back to the 6N1P. 

 

Hope this review helped!

Nice, useful impressions.

I hesitate to mention this as I fear for your wallet but you will likely enjoy the many tube options listed in the lyr tube rolling thread evil_smiley.gif

Hahaha, yeah I've been well aware of this... issue... diving into the Lyr instead of the Asgard 2. Your warning to my wallet is as useless as you thought it would be tongue.gif. Sorry wallet! rolleyes.gif

Thanks to toschek for your guide! Very useful.

People who find the leds shining too bright might just want to not put them back in their holes. Either gently folding or setting them upright could be an idea.
