Also how does that amp sound? I was thinking of getting one for the purposes of hooking up for my speakers and what not (would also have for my iPod too), but was curious what you think about it. Also, that price is a bit steep from the link that you posted, I'm guessing that you didn't actually buy it from that site?
That's actually an insanely good price for a tube headphone amp that also powers speakers. It's at that price point where diminishing returns starts, it's not too strange for A/V nerds to spend a thousand and up on components like these so 350 for a chinese made stereo tube amp is a damn good deal considering it'll do the job better than something you can get at best buy for 2-3 times the price.
Grado is a pretty interesting company, but I think you might be exaggerating about them Ragnar. Obviously they have some sort of device to measure the frequency response of the drivers because all the specs are listed on the site. There's definitely a "Grado Sound" associated with the headphones though, the mids and highs are very punchy and sharp while the bass is a little shallow(yet accurate) compared to most headphones in their class. I used to have a pair of SR80i that were awesome and my buddy has SR325i's hooked up to a shitty amp and they're some of the best headphones I've listened to.... BUT I also like to listen to a lot of rap/electronic/dance music that can really lay the bass on thick and the 325i's don't handle that so well so I was wondering if the RS1i's might.
Speaking of Bose, I've got a pair of their on-ear foldable headphones from a vending machine in an airport 'cuz I forgot my headphones and I gotta say if they were a hundred bucks cheaper I'd recommend them to everyone as a go-to pair of headphones for unamplified portable player because, aside from being a little too bass-y, they're not too bad!
