Just thought I would post to say that I wanted to upgrade my setup and get a high-end sound with headphones without going nuts on cost.

I tried the HD850's and settled on the HD650's as I thought they had more bass. For the DAC everyone seemed to be using Hugo DAC's at all the demo booths I visited so I bought one blindly.

I placed my spotify account on notice and moved to Tidal.

I have conducted some blind tests of my own, using mp3, Tidal and SACD souces with and without the DAC using a Alienware 17 R3 laptop which uses a Recon 3Di board (which I assume uses a Cirrus Logic CS4382 DAC) and a reference point in the shape of some closed back Bose QC25 phones.

Summary is, the HD650+Mojo combo is pretty incredible, the most notable difference between using the Mojo DAC and not using it is that the band instruments on a track can be heard individually. I did not think the external DAC would make that much of a difference but it does.

The other surprise was Tidal, its a pretty awesome source of material. To the point where I am looking at my Mp3 collection and considering deleting it all as it has been comprehensively out-moded and out-dated.

In terms of SACD, if there is a difference I think its with orchestral music, pop music, rock and everything else I tried did not seem to benefit to my ears.

The biggest difference is of course, the headphones, they need 100 hours burn in but so far they are well beyond anything I have heard at this price point. Highly, recommended! They are still very capable without the DAC however, you lose about 15% of the music quality (if I were to put it into numbers).

In terms of cost, I managed to get the HD650 cans with the promo 45% discount (£240), the Mojo I paid full whack for (£399).

No snazzy cables or accessories required.

What was the exhibition (booth ref) when you tried Dac's, did you audition others ?
So is the Mojo fine without need for any equalization, that is really a pre-requisite for me, that you do not have to put (well) questionable pieces of software in the sound path.
Equally, no hum problems ?, or is there some optical isolation in it if you choose to use it with a phone, or lower 'quality' front end eg phone

Tidal, yes, I discussed that in another thread not yet started my trial , but looking forward to some good flac, it is primarily american no ? so I was perhaps concerned with getting bandwidth to their servers
 
I went to canjam.

there is no hiss on the higher end DAC+amps like the mojo. I know what you mean though. I have not tried it on my phone yet.

I have no problems with tidal in terms of throughput, I even stream over 4g on my phone.

tidal has an offline option so you can download on wifi and listen on the move without a connection.
 
I bought a mojo and ended up sending it back. Just didn't notice any improvement at all over my SMSL Sanskrit 6th USB DAC. Was only using it purely as a DAC into naim hair 5i and some decent rega speakers.

Was left very disappointed by the hype train around the mojo .
 
yeah I suppose in terms of larger form factor DACs there are plenty of cheaper options. the o2 for example.

from what I understand the mojo offers a really good amp plus the dac in a small portable package which is hard to beat. I looked at alternatives but the mojo has a really strong amp which I can use to drive a wide variety of phones with. alternatives I looked at included the oppo.

what you think of the Sanskrit? a lot of people seen to think the specs look bad?

Do you think i would hear the benefit using one over a E10K purely as a dac (using Little Dot MKII as amp)
 
Did a blind test between spotify premium and tidal lossless. Couldn't tell the difference with my HD650. Which is fortunate as the price of tidal lossless takes the ****.

Really like it, so much so I bought a second for use in my back room where it's hooked up to an nvidia shield TV when it on music duties.

Well built for the money
Just works, some can be a bit flaky , especially with the shield TV.
Sound wise, again no complaints. Before I sent the mojo back I did some A/B testing and couldnt tell a difference. Both are noticeably better then other , cheaper DACs I have tried.
 
About Tidal cost : I maybe wrong - their premium with flac is £20/month and basic of £10 runs the same as spotify premium both giving 320Kb/s mp3 or 192Kb/s AAC.
Agree £20p/m is a lot , £10 is too and 320/192 is minimum I want for home listening (speakers not headphones).
I will comment more when I have had my tidal flac trial.
[concern is now that music is being mixed/produced for the more typical headphone environment - the home speaker customer ignored]

Anyone with half an ear for music would probably be impressed by it coming from your average DAC/integrated audio, etc. where the cheap and nasty workhorse capacitors, op amps, etc. kill a good bit of the separation and imaging in music without necessarily realising it isn't something unique to the mojo.
 
it's not unique no but if you want a portable amp plus dac with enough power to drive bigger phones then the choices are more limited.

if I did not want portability then a £130 o2 amp would be fine
 
O2 is decent but designed to prove a point - subjectively I found the sound far more enjoyable after some modifications - especially separation and depth - the JRC4556 output op amps while good with high current requiring headphones have some issues with HD600s and the likes IMO.
 
Rroff - what would be your choice of non-portable optical/usb DAC, not necessarily with an AMP, in the £130 range. ?
( when you said "O2 is decent but designed to prove a point" I assume you mean it has been designed to a specific/limited cost point - £130 )

With respect to SMSL, both Amazon&head-fi reviews do criticize their reliability (both Sanskrit 6th USB & 793 II), and I would hope that the Mojo is better in that respect, although, very few reviews show a tear-down with pcb board design and components reviewed ... but clearly you have some knowledge here.
 
TBH I went down the DIY route as I never found anything I was completely happy with - at that price I'd probably be taking a long hard look at the Schiit Modi 2 uber DAC wise but there are other options as well.

The O2 amp was designed to prove a point in that you don't need overly complicated designs using £1000s worth of boutique/brand name components to get high quality sound. The problem is while it performs great the designer went to great lengths to spec the minimal component to do the job (to prove the point) and there isn't a huge amount of allowance for error margin or use outside of the specifically intended situation, etc. The DAC was an extension of that but built using the best of what was available at the time with quite a lot of limitations.

SMSL are largely copies of established ("open source") designs (though few amps or DACs are truly unique or different design wise).

Esoteric solution eh - nice one.

Thanks for your suggestion, I am currently using an older echo audio cardbus dac, but has no driver support with win 10 and cardbus/expresscards rare on laptops now;
albeit it has an a2d too, so have done some vinyl rips for portable use.

You are using a crap DAC and a crap amp then, or you are half deaf.

I can hear the difference even on garbage equipment. With a TEAC UD301 feeding a Schiit Asgard feeding Hifiman HE400i's the difference is absolutely night and day.

Honestly you guys should be listening to SACD rips. Not that PCM crap but actual DSD stuff with a DSD capable DAC. That stuff sounds insanely good. Sure, 25GB albums are a pain in the arse to store but still..

Also, if we're talking about running off a PC, there are a lot of factors to consider to get the best audio possible. Does the PC have moving parts? (fans, HDD) that's bad. Are you using something other than MAC OSX or Win 10? That's bad too.

For serious listening you should go into your sound adapters properties and click the "turn off all enhancements" dialog box.
 
Depends a bit track to track with Spotify as well - some are like night and day difference with Spotify sounding like a 96kbit MP3 even on max quality while others on Spotify are quite good and I struggle to tell the difference versus a lossless original.

I'm with you on that - some tracks on Spotify sound noticeably better than others

pity Spotify don't offer lossless :(

interesting to see what Amazon music premium do to the market - if only they were to introduce lossless it might force the hands of the likes of Spotify

I think the user interface on Spotify is fantastic

I personally use an E17 DAC - but only with my Tablet - a Samsung Tab S - as I find the Note 3 headphone output about as good as the E17
