Cross-posted from the Mojo thread, might be of interest to those following this thread also:
Interesting for a few reasons. With regards to the T5p, they're fairly neutral, although on the brighter side of neutral, and a bit bass light to my ears. Their main deficit for me though is how lean they are - it's not a matter of they are neutral and the Mojo is neutral and so the pairing is not ideal. They definitely want a pairing that is warmer and has a bit more body than the Mojo I think (EQ'ing will help somewhat). I had a similar take tonight comparing the Mojo with the Geek Out V2 with the Ether C. I need to compare more formally, but I think the Ether C is a little on the leaner side too, if not as much as the T5p (and with a better bass response).
With one DAC/amp plugged into each side of the laptop, and after volume matching them both to 75dB with a test tone, it was pretty straightforward to switch - just left the audio devices setting window open and changed the default playback device when plugging into the alternate DAC. Still a slower changeover than I'd really like, given the brevity of audio impressions, but at least the volume matching persisted through changeover. Listening to the GOV2 was via the balanced output, and mostly with the default TCM digital filter mode. Almost all files were 16/44 FLAC, with one exception being some 24/96 Pink Floyd. Music choices varied a fair bit - Rage Against the Machine, Pantera, Ella Fitzgerald, Alanis Morissette, Miles Davis, Tool, Muse, Massive Attack, Pink Floyd.
I tested for an hour, which is probably as long as it's worthwhile to test for with this kind of listening (and certainly my limit at present, as I recover from a cold that featured some unpleasant eustachian tube dysfunction last week).
The last time I did a "DAC-off" was with the Auralic Vega and PS Audio Perfectwave Dac II, and there it took some time to acquaint myself enough to discern any difference, and even longer to drill down into that and realise where, specifically, the differences lay. In that case the sound of cymbals was about the only area where I felt I could reliably hear a clear, if slight, difference (with my preference going to the PWD2, which I felt sounded more natural with cymbal sounds). That took place over a couple of weeks, and I still think a blind test would be the sternest of challenges for me...
In contrast tonight I could hear that there was a difference between the Mojo and GOV2 immediately, and in terms of specifics the bass difference came through pretty rapidly. With the GOV2 the bass was more weighty and impactful, the sound overall more dynamic, which made it a better pairing for the Ether C than the Mojo to my ears. Cymbals sounded a little more splashy with the GOV2 however, and I would imagine over a longer listening session it could be a bit more fatiguing (although I may be overestimating that, given I am a bit more sensitive to sound with the nearly resolved cold). Interestingly if I changed the digital filter on the GOV2 to the FRM filter it was less fatiguing, cymbals were a little better behaved, and it sounded closer to the Mojo signature, while still retaining some advantages in bass and dynamics. Soundstage and detail retrieval seemed similar to me, and it would take more sessions to meaningfully flesh out if I could hear any differences in those (or other) areas.
Take all that FWIW, I’m getting over a cold, and I think as much as anything this might reflect one headphone pairing and shouldn’t be generalised. If I have any time before returning the GOV2 I will try with some other headphones (perhaps with MHP1000, which are not lean in the least, or perhaps with the Pandora Hope VI too) and see how they fare with the respective units. What I would still take away from this is that the Mojo isn't necessarily going to be the be all and end all for all headphone pairings.
When/if the V2+ becomes available I will likely buy it and have a fairly lengthy comparison period including some multi-participant blinded tests. After this evening, I could perhaps see myself selling the Mojo.
