People exaggerate. I have the SS and the RWAK240, and differences, if they exist, are below 1%. I think the music might be more vibrant, but it might just be the added echo from the emptiness of my wallet.
And I would like to remind I sold NT6, 901, Hugo, Kaede, etc. So this is easily financed. I realised I just need one or two awesome DAPs...and the RWAK240SS is quite a treasure, although a very unreasonably priced one to say the least.
