in regards to the v2s it might not scale as high as the monk plus, (like plugging them into a desktop amp and getting way more clarity, etc) but it does come with the benefit of being 32ohms only. easy to drive, without the need of an amp.
i have the same feeling with the chaconne, but with how sharp i perceive the highs, it ends up hurting my ears, can barely listen to those for more then a few minutes. it was one of the more expensive buds i was thinking about before i started to know about VE
also do get the 4.4mm version of the v2s. they sound wider and due to how wide the headroom is and its technicalities are further enhanced they are when compared to the 3.5mm version.
also i would also recommend snatching the abigail pro 4.4mm as well if you have not already. the v2s should still have the bundle available. if im not mistaken its basically getting the abigail pro at half price.
its loaded with a custom firmware and its actually more powerful then the old not by ve abigail.
oh and fyi, the monk plus is technically the 5th version right now, iirc it sounds slightly different then the monk plus you have, but only slightly. its tends to show up when running on a desktop amp, slightly less bass, and abit more forward in the mids. you can tell if you see a small VE logo on the driver cover
also if you are able to maybe try looking at the Monk Pro Vita, they are for me the coalescence of what the monk series is.
little something i wrote about them sometime ago
