Sorry to take a while to reply to this. My listening impressions are with predominantly the ifi GO Bar. However, I have also recently hooked the Ripples up to the Valhalla 2 and needless to say, things only get better.
Well, the first source I actually used was the M8 and I was somewhat disappointed with the within-the-head presentation and this is quite unlike the M8. It tends to provide a decent stage. I switched soon after to the ifi Go Bar and things were considerably more separated and stage much more extended in air and dimension. It's a perfect matchup. I think the ifi Go Bar has a particularly powerful amp stage and gives a good bit of drive which helps. Out of curiosity I've played around the Valhalla 2 and again things scaled up - the Valhalla always opens my earbuds, while adding a beautifully organic texture and character to things. Again, this is a great synergy that pairs well with the detail on offer with the Ripples.
Long story short: source is definitely at play here.
These comments pretty much hit the nail on the head. I understand your difficulty trying to describe what you're hearing, trying to compare the intangible/psychoacoustic/spatial properties is never easy and highly subjective. Having said that, how the midrange is handled/tuned on the Ripples places elements closer and adds emphasis that naturally has the effect of tightening perceived stage dimension but there is still a 'furthest extent' to the stage that I try to establish in my minds eye. My feeling is that this 'furthest extent' is larger on the Serratus.
What the Ripples excels in, better than the Serratus and Alpha in my opinion is 'imaging' within the stage which gives it that ethereal and dimensional quality. I will always index for better imaging than absolute stage width. It gives life, body and shape to instruments and everything is infinitely more enjoyable. If I can have both, which the Ripples does offer to a very good degree I might add, then great!
I think we're both hearing the same wonderful replay here. The longer I listen, the more I can see it supplanting the Alpha as my go-to. The Alpha is a whiskey and warm fire type earbud and the Ripples a stimulating and dynamic listen. It's quite a magical little set and reminds me of the Traillii in that it's deep, naturally revealing and exceptionally balanced. Except, we can one up that here with a more authentic DD timbre and impact when called for (the Traillii was the best BA bass I have heard but it was still BA bass).
Listening to this the Ripples conveys every last drop of texture and detail. Alot of DD's struggle with the bass in the left channel on this recording, it loses texture quite easily, but not on the Ripples.
Thimar is one of my favourites from Anouar, impeccable taste

Definitely an album I'll listen to once Alpha and Ripples are here
