Hey! Any chance you could elaborate on this a little?
Would you say the difference between the two is significant or just incremental (ignoring price, purely the sound)? e.g. swapping between them is it immediately clear the RS1i is better in every way, or do you need to listen more closely to perceive the differences?
I'm debating a move up the Grado ladder, but I also have some 225i and a set of vibro cups and I'm wondering if I should just save my money and stick the wood cups on the 225i ... I don't want to spend £££s on incremental improvements, I want to be blown away
