Newbie here. The Mojo drew me to this forum. Some great information guys. It's been hard keeping up with the posts (so many), but I wanted to post my thoughts on the Mojo I got at Christmas.
I primarily use Grado SR325's, but have all sorts of free headphones and IEM's. Unsurprisingly the Grados sound great.
What shocked me was how different (better) all other devices sounded. I have some ancient Sennheiser MX500’s I use at work for webexes etc. Occasionally I try to listen to music through them and they always offend. The Mojo can’t make them sound great, but it does make them play music rather than shriek awful noise. I found I’d listened to 9 full tracks with them and enjoyed every minute.
My music collection is mostly FLAC, having ripped all my CD’s several years ago. I have a growing 24 bit collection which always sounds excellent. Overall I find that the 16 bit FLAC music all sounds better. Cymbals and drums particularly are improved with them sounding different for each artist.
This would be good enough to justify buying the Mojo. The bonuses are with MP3’s, DVD’s and as a source for amplifiers.
Simply put, everything sounds better via the Mojo.
Connecting to amps the harshness I’ve always associated with CD music is gone.
DVD’s, particularly those with old film material, amaze me. I watched Dr Zhivago on the laptop, connected it to Mojo then to a Monitor Audio S200 speaker. The movie never sounded so clear. It’s got me trying all sorts of movies now.
The biggest surprise was MP3. WOW! I never liked MP3’s due to the reduced dynamics, harshness and overall loss of detail. Some music is only available as MP3 so I bought it, and had to live with the artefacts. I listened to some 320k MP3’s the other night and my jaw dropped. The Mojo brought out stuff I had never heard before. I have a Linn DS system which sounds great with well mastered files, but exposed what I always accepted as inherent flaws with lossy material. Mojo can’t fix the dynamics, but it finds detail the Linn never does.
This got me listening to DAB radio through Mojo. For those not in the UK, digital radio is based on 64k mono to 192k stereo MP2. YES, MP2. It is as bad as you’d expect. Even this rubbish sounds better through Mojo. The 192k BBC 3 station actually sounds pretty good.
I’m enjoying every day with the Mojo and listening to old albums. So many sound better. I’d recommend this to everyone who has an extensive MP3 or AAC collection. Don’t waste your money on buying them again in a lossless format. Buy a Mojo and that’ll upgrade your whole collection in one go. It really is that good.
