Agreed. The $500 range is pretty crowded now with noble universals, and the recent liquidation of aurisonics asg series.(noticed how many keep popping up on the for sale forum lately?)
The aria looks very nice indeed. I love that it's a quad, and clearly that response curve is quite a beauty. Honestly it looks very similar to the old audeo pfe series response curve, witch is a good think. I had the pfe 132, witch is only a single BA and I always thought it had absolute phenomenal sound. So if the aria sounds similar, it will be a beautifully coherent sound.
I'm glad you got me hip to the aria. I am currently building up funds for my one last hoorah in my decade long earphone hobby. I want a final set. I've raised almost $600 for my one final stab at absolution.
You've just made my decision even harder lol. Aira, asg 1Plus, ath im04, or the new aluminium noble savant. These are what keep me awake at night.
The most I've ever spent on a single set of earphones is my RHA T10($250) my fx850($275) and very recently I decided to choose the aurisonics bravo series forte as my last purchase($400) but I did not enjoy the sound from the Forte's and sent them back. So now I've gathered up what I feel I need to acquire a single piece that will accomplish many things: sound great, look great, fit great, be built well, last for years and most importantly, truly represent the current state of the art in in ear technology.
I've yet to decide, but I'm leaning towards the asg 1Plus. Now that I've seen aria,I don't know...
