I love the sound of both versions! Really wonderful sounding speakers. I found a slight preference for the V2 which sounded a bit more complete to me. However, I would need to be in that room listening to be sure.
The Vcap Odams are great in speaker crossovers. Vibrant and so very open. They are also easy to fit due to their relatively small size. However, I would say they are my 2nd choice in this particular speaker. The best choice, if you can afford them, would be the Duelund SnCu CAST caps. This is their tinned copper foil cap. The richness, realism and natural tone of this cap would be a better match in this speaker. I think this speaker would benefit from the body, richness and meat of this cap. The Odam may deliver more perceived air and liveliness, but I just don’t think this speaker is asking for “more” of these attributes. Just my opinion.
If these are too costly, then the Jupiter copper foil cap is also a great choice. Keep in mind the size of both the Jupiter and Duelund can be quite large depending on the value you need.
I am making an assumption these speakers don’t currently have a top tier copper foil cap in them. If they do, then wonderful and leave them be 🙂.
