well I recently bought the RHA T20i as an upgrade and the sound was obviously better but I wanted a bigger improvement in sound quality.
I pre ordered the vibro labs Aria this week. Theres a review on here of them if you ain't familiar with them.
When ai had the T20 and directly compared to the ex650 It was apparent how dark and tinny sounding the ex650 were. Probably not the correct way to compare as it will make any differences more apparent
Yup I saw you mentioned the Aria in your previous post. Checked it out and it looks interesting, will look into it more when I have the time.
Well if you're looking for what personally suits you, there's no "proper way" to compare gear. There'll always be things you like and don't, so if comparing the T20i to the EX650 makes it clear what you don't like about the EX650, I don't see what the problem is. As long as your wallet can keep up.
And that's the problem all audio enthusiasts have... The cursed constant need to upgrade is real haha
