Schiit Bifrost with USB & Uber upgrades


Category: Digital

Schiit produces a very focussed line of high quality products, at a fair price, with some interesting design features - and they only sell direct (hence the fair price)

The Bifrost is their mid-line product, being surrounded by the Modi as their entry level DAC and the Gungnir, the top of the line model

I opted for the Bifrost model mainly because I had identified very specific requirements which the Bifrost matched completely, which were….

- 24/192 on all inputs USB,
- toslink and s/pdif inputs
- onboard Mains Power (none of these silly little external supplies)
- amazing sound

I also opted to forgo the “Balance Design” of the Gungnir in order to save on cost. Hmm, maybe I should have splurged, but then, there is chatter about a new completely “tricked out” model in the development stages

The only problem with Schiit being a direct-sale outfit - there really is no possibility of a side-by-side audition. But apparently, you can opt to return the DAC within 15 days if it fails to impress at audition time - i.e. for a 5% restock fee + shipping (please contact Schiit for full details)

I did a lot of reading and people seemed to be quite generous with their accolades, so I took the plunge and placed an order.

I opted for the Bifrost with the USB input ($100 extra) and the Uber analogue stage upgrade ($70 extra) for a grand total of

Since I’m in Canada I elected to pay around $60 for the mid level (expedited) postage + tracking and on arrival, another $70 Duty and $10 handling - Grand Total $660

I placed the order Friday afternoon - within an hour the unit had shipped! The following Tuesday, around Mid day I was signing for the parcel. - now that’s Service!

Once unpacked, I put the little sticky feet on and left the mains lead provided in the box where it belongs!

I found, by way of experimentation with my previous DAC that a good mains supply is paramount when delivering good performance. I had replaced it’s meagre Wal-Wart power supply with a DIY supply providing much more headroom.

With on-board power supplies the only thing you can hope to improve is the power cable and since I just happen to have a Furutech handy I powered it up.

I first connected the Bifrost to my iMac via a DH Labs toslink (optical) cable, which I have found to be completely trouble free and very good at data transfer - rated at over 150 Mbps. The interconnects I use are Stager Silver Solids - 1 meter in length.

I played through several of my favourite audition tracks and right out of the box the Bifrost had already exceeded my expectations.

Prior to ordering the Bifrost I had gone to local stores and auditioned several higher priced DACs, including: Wadia 121 decoding computer Mytek Stereo 192 DSD DAC Chord QuteHD DAC

Now I’m not going to say the Bifrost is better than these three, since they are many times its cost, but it comes very close to two of them and to these ears, was better than the other one.

What I found was that the guys at Schiit are deadly serious about producing high quality audio products

The bass frequencies go very deep and are very well controlled - my favourite pipe-organ tracks now sound extremely realistic with those low notes that have the unmistakable rumble and the high notes are crystal clear and uncluttered and you can hear them breathing. The high frequencies are extremely well behaved - strings seem so much smoother, you can hear the air crossing the mouthpiece on flutes. Reproduction of sibilance is superb. Dynamic control across the board is extremely good and a vast improvement to my previous DAC The fine details that puts you into the recording venue are there and this is really highlighted on orchestral tracks and live music The stage is huge in width, very good in height and cavernous in depth - again pipe organ tracks project way beyond the back of the speakers - I was sitting in a Cathedral.

The musicality is another outstanding achievement by the guys at Schiit. The sound is much more analogue than digital and as the unit breaks in that attribute is just getting better. I have not yet found myself fatigued in the months since its delivery.

Streaming internet radio has also taken on a new quality and I can even listen to the classical and jazz stations for longer periods with the Bifrost in place.

What about High Def. Digital Audio you say?

The bulk of my collection is 16/44-48 with a few 24/96 tracks and a couple of 24/192, but the Bifrost handles HD tracks with amazing dexterity.

My previous DAC was an up sampling DAC, so everything got up-samlped to 192kHz - and it didn’t do a great job of that.

The Bifrost processes the sample rate it’s given, so whatever you throw at it, that is what gets converted - no up-sampling! The net result is there is no interpolation going on to fill in missing samples and that seems to result a “crisper” presentation. There seems to be more snap in the drums, more whispery textures in the vocals, but strangely, strings seems smoother and not brighter, probably due to the Uber upgrade.

SIDEBAR: I use an iMac to stream music files, and the iMac has program code that “messes” with the digital file for up sampling and volume control, ultimately colouring the audio output . To avoid this I installed a program called Audirvana Plus - a program that bypasses the internal iMac sound processing code and passes the data at the sample rate recorded. A nice feature of Audirvana Plus is that you can elect to have it integrate with iTunes or operate as a stand alone player. I choose to integrate it with iTunes to allow for remote control using my “Droid” tablet via an app called Retune.

One last item to test - the USB and s/pdif inputs - yep - they work! and they sound no different from the toslink to these ears - so I left the DH Labs USB cable in place.

For the s/pdif input test, I connected my DVD player. To my surprise playing a CD track sounded the same as the same track streamed from the iMac.

I could go on about the dynamics of “this track” and the delicate textures of “that track”, but then you would have to know those tracks intimately to understand my rantings.

I will go on record as saying this is an exceptional value for money - and I mean EXCEPTIONAL!

It is very close, performance wise, to the other units I auditioned and to be quite honest, I think that if I was to hear them side by side and budget was no object, I’d still select a Schiit - maybe the Gungnir instead of the Bifrost, but based on the performance of the Bifrost with the Uber upgrade - I think it too would also be a very close call.

If you need balanced outputs then the Gungnir would be the model to go for. For the extra $300 - you actually get a completely balanced design with dual transformer power supply and analogue sections, This should elevate it’s performance to the “next level”.

How much better? - that’s the $64M question.

Oh - I almost forgot - this little puppy is also upgradable, so as newer circuitry gets developed you can upgrade - e.g. the Uber Analogue upgrade is an example of this feature - if you don’t have the funds for the Uber right away - you can upgrade later - same goes with the USB input circuitry.

A base model Bifrost starts at $350 - AMAZING!

So I now have a piece of Schiit on my hi-fi stand and my wife didn’t give me any (shit) because it was much less than my original selections

To sum up - The Bifrost is a no-nonsense, no-frills, basic inputs, no remote, get off your backside and select the damn input yourself kinda DAC!

If you want frills - go somewhere else - but ya ain’t gonna get an audio experience as honest as this one unless you spend 3, 4, or 5 times the money!

Yes - it’s that damn good!

My most recent upgrade was to the Stager Silver Solids interconnect cables by adding Eichman Silver Bullet RCA connectors which allowed the Bifrost to demonstrate just how good it really is - a well worthwhile upgrade - more space, improved dynamics etc..

Hello Willie:

I loved your review especially since I own the Bifrost Uber+USB. Your point on power cords got me curious. I live in India and I may have to order one from abroad. What cable would you recommend for 220V, 50 Hz supply ?

Thanks and regards

Koth
Koth - I thought I had posted a response and noticed this morning that it was not there - must have pressed the wrong button - sorry about that.

Well, I have found that devices that operate at a higher voltage, in your case 220v, tend to experience less benefit than those that operate at lower voltages such as 120v

Not to say that you will not hear any benefit, but you may require a significantly better quality cable.

First a couple of questions
1. what mains plug do you use?
- 15 amp round pin
- 13 amp square pin
- Schuko
2. what do you want to spend for this cable? (in $ please)

Some people may think I am crazy when they learn that my cables (power + Interconnect) cost as much as the Bifrost itself - fact is, the Bifrost is capable of so much more than it's modest price tag would suggest - it just needs to be set free :-)

If you are at all handy and can attach plugs/connectors to a piece of wire, then the DIY route will get you the best "bang for the buck" - let me know and I'll send you the details. As an example - I just made a power cable for about $35 that performed almost as good as cables 10 times the price.

Let me know your preference

Regards...
Well - in the last few months I've packed a few upgrades around the Bifrost

1. Upgraded the power cable to a DIY Spiral design
2. upgraded the interconnect to a DIY spiral design
3. upgraded the USB to the cable below

Power supply and USB cable separate audio signal cable

This USB cable is nicely made and performs better than my DH Labs USB cable - even when plugging both data and power leads into my iMac.

For details on the DIY spiral design cables see the "System" link below

The new USB cable provided significant improvements of the very fine details and image, but the source of the USB power is crucial.

Power sources I have tried include
1. plugging power and signal into my iMac
2. plugging into a no-name USB power adapter
3. plugging into an Enercell or ASUS USB power adapter
4. plugging into a USB rechargeable battery

1 was not too bad but 3 & 4 were better
2 was the worst
3 and 4 were the best and equal in performance

This USB cable would enhance any DAC that utilizes USB power like the Bifrost does.

Schiit also has a "Decrappifier" which costs $100 and you'll need a second quality USB cable. No idea how good it is, so can make no comment, but this two lead USB cable eliminates the need for yet another component.

I had always wondered why Schiit chose to use USB power
- now it is quite clear, yet another product for them to sell to you.

if you want an even better USB power supply, take a look at the Teradak line of products - they appear well made and are reasonably priced.

But the Enercell or ASUS USB power adapter performs as well as battery power and they are much cheaper than the Teradak.

That's about it - this source is now complete and sounding fantastic.

Will there be better DACs? - probably, but this one is staying in my system for the foreseeable future.

Happy Listening :-)
One last update...

I have just found out that the ripping software can make a considerable difference in the performance this cracking little DAC is capable of.

I ripped a few of my best CD's using dbPoweramp and WOW! - what a difference.

It really revealed the true resolving power of this amazing DAC.

Just google dbpoweramp - their web site allows you to download a free full function 21 day eval version to try out.

Give it a whirl - even if you have some other DAC - it will make a world of difference

OK - second last update...

If you a looking at getting a USB port for your Bifrost or Gungnir then get the v-Link192 instead.

It's $15 cheaper as well, but you'd better hurry - Musical Fidelity have discontinued them - but they are on eBay

It is a significantly better USB implementation than even the Schiit USB Gen 2 - and I mean significantly.

I just upgraded and was extremely impressed with its performance.

It really allows the Bifrost to show just how good of a DAC it really is.

I would love to hear it with the Gungnir :-)
