Yeah, I understand that and I don't think you have any ill-intent at all. Its a totally fair worry to have.
My main concern is around a 'cult of Trinity' that is slowly taking shape, hardly just from yourself. From some users, its pretty clearly tongue-in-cheek, others not so much, and either way its a kind of hype. Inevitably leads to arguments, generalizations, and people taking things personally.
I think part of the problem, though, is you just won't know until its in your ears. I'd hate for someone to tell you you 'must' have this x hundred dollar amp or dap to get the 'best' out of the Master 6 and then it just doesn't suit you at all - whether it be the Master 6 itself or some part of the chain.
My intent was to allay the fear that anything will sound bad out of a recent iDevice, if you're happy with how it performs with what you have now, then its unlikely to be the problem with anything else - more likely it'll be down to how well the Master 4/6/Hunter/any other IEM suits you.
I appreciate your comments, all very valid and spot on! I understand, I have to listen with my ears. I really worry, I won't appreciate the high end IEM from any manufacturer due to my ears and perceptions. I realize my sensitivities and needs are individualized to me and different from many of the members here.
I made my previous purchases based on certain user reviews on head-fi. There are some excellent members whose reviews have allowed me to determine the sound signature I prefer and what to look for in an IEM.
I have not and will not go out and buy amps/DAC before listening to see if I need something or want it.
Thank you for reminding to be realistic and not get misguided.
