I have to disagree, IMHO compared to other ciem's and iem's I would say the soundstage of the roxanne is a significant strength.
My Leckerton UHA760 does very well with them. The Hugo was nice but the price is not. But since I got the AK120 I don't use an amp. Only used it with the DX50.
Same here, the soundstage is the first thing you will notice that is different from Roxanne compared to other in-ears. It's comparable to a headphone imo. Which resemble the presentation on an Audeze headphone.
