REVIEW: Schiit Bifrost DAC


No - it’s not a mis-spelling - the company really is called SCHIIT

It was calculated and they play on it - but despite their apparent sense of humour, don’t go thinking they are in it for a joke - these guys are deadly serious about hi-fi!

They produce 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 Gugnir, 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 (OK - we all want that, but how good could possibly it be?)

The only problem with web-based outfit - who knows how good they are - there really is no possibility of a side-by-side audition.

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 $520

Since I’m in Canada I had to pay around $60 for the mid level postage 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 than actually required.

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 well broken in Furutech FP-314 Ag - a 15AWG α (Alpha) conductor power cable handy, I powered up the Bifrost. Yes, cables make a difference.

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 - i meter in length. Interconnects matter also.

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 and I’ve put in several hours listening so far.

What about HD Digital you say?

The bulk of my collection is 16/44 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 - go figure.

SIDBAR: I use an iMac to stream HD, and the iMac has a silly setting that also up-samples. To avoid this you would need to install BitPerfect - a small program that passes the data at the sample rate recorded - it’s only $9.99 from the Apple Store.

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 disk 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 with the Uber upgrade I think it would also be a very close call.

If you need balanced outputs then the Gungnir would be the model to go for.

So I now have a piece of Schiit on my hi-fi stand and my wife didn’t give me any because it was much less than the competition.

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 2, 3, or 4 times the money!

Yes - it’s that damn good!

UPDATE:The 4490 board arrived this morning and has been up and
running for around 2 hours.

My old Bifrost environment was
- Uber Analogue Upgrade option
- V-Link192 in place of the Schiit USB port
- excellent power cables, USB, IC's and SPDIF cables

I have always liked the Bifrost for it's "spirited"
and detailed abilities, but the 4490 has now upped the anti in
a very good way...

- The dynamics are a little more punchy
- The image is very cohesive - the best I've ever heard it
- the mid-upper frequency details and clarity has improved
- The high end has much more body - not quite so shrill
>>> upper register of violins is much smoother
- Micro details have improved
>>> excellent venue acoustics reproduction
>>> significantly improved decay of cymbals
>>> more whispery textures on vocals

The upgrade from the Uber Analogue to the $70 4490 was well
worth it, so I would imagine upgrading from a stock Bifrost to
the 4490 would appear even better.

I was not impressed with the USB Gen 2 upgrades, since its
performance was trounced by the v-Link192.

But the 4490 upgrade shows that the Bifrost Team can pull off
a very worthwhile upgrade for a very affordable price.

This is as close to analogue as I've ever heard it!

It should be really nice - once it's burned in :-)

Well, after 11 days continuous burn-in the 4490 has provided an exceptional improvement in SQ and is providing the most cohesive reproduction I've ever experienced on my system.

All aspects of fidelity, i.e. timing, image, spatial accuracy, dynamics, clarity, and details have exceeded my expectations for a $70 upgrade. Only leaves me wondering what the Multibit is capable of.

Comparing the Uber Upgrade board to the 4490 reveals a remarkable similarity in the components used and their placement - I would guestimate 90% the same - which leads me to believe that the Uber Upgrade is also included.

If you are considering 4490 upgrade I can highly recommend it :-)

Regards...
Im curious why you didn't go with the multibit... $? I have a bifrost uber as well and was going to go multibit because I didn't think the 4490 was much better than the uber...
B_limo - I'm in Canada and subject to conversion rate and maybe even duty.

I priced the multibit and took into account the time taken the ship the unit there and back, plus the price of the upgrade and shipping cost to and fro and possibly duty. It started to get expensive by comparison to going the 4490 route.

The 4490 was a much simpler upgrade process and significantly cheaper. No duty either.

Turns out the improvement in SQ was far greater than I had thought would be possible, which was a bonus

In my mind, if I were to go with multibit, I would also upgrade to the Gungnir because of its superior design.

I'm not really considering the yggdrasil at this point in time - to $$$

The Bifrost 4490 is a very capable DAC with the right cables and when used with a USB-SPDIF converter like the v-link192.

Unfortunately, I did not find the Schiit USB Gen 2 upgrade to be in the same league as the v-link USB interface.

That's about it :-)
