I got my Spiral Dot Tips off of EBay. The ML size fits me if I get a deeper insertion with another cable, but isolation is not as good as tips like Comply foam tips. Although I probably need the large tips for a better seal. Note that the Spiral Dots are more shallow compared to other tips.
I also tried ML spiral dots with adequate but not stellar results. However, I received a pair in Large from Dopaminer and that additional size permits a nice external canal seal and the best bass, detail and overall musicality I've experienced with my A83's. I pretty much fell in mad love with the Fidue's all over again after using those tips...I'm not cheap but I guess I am easy.
