I love Sound ID reference, and I find it much better than Reference 4.
I have a suggestion. Why not adding the possibility to upload one of the headphones profiles to the translation check? I mean, after flattening the curve using one's user profile it would be useful to be able to listen to how a specific headphone of your database changes the curve. I think it would be of real help when dealing remotely with a client whose feedback is based on the headphones he/she uses, allowing us to check what the client is actually listening to.
