No it's not crazy. Yeah, sucks that you missed the $150 deal but if it makes you feel better, I bought my 2nd X1 at $300 just 3 weeks before the $150 deal. And no I wasn't able to get a refund.
As for being worth $100 over the HD558 or not, that certainly depends on what you want. The X1 is definitely, heads and shoulders, tip and toe better than the HD558 for gaming, this I can assure you as I do use to have a HD558 mostly as my main headphones for games. As for electronica and pretty much mostly every other genre, the X1 does very well in them. The HD558 is a rather decent all-rounder too, but it certainly wouldn't excel in electronica and rock IMO. The HD558s focus is on the forward mids with a very slight bump in the mid-bass, it is also a brighter and less warmer than the X1.
I'd say go for the X1 and it would be a headphone that should last you a very long time before you'd feel the need to upgrade again. If $230 is a tough pill to swallow, then perhaps wait for another sale?
Thanks for the feedback. I can be patient. My wife won't be gifting me the headphones I pick out until closer to my birthday at the end of March lol. Here's hoping for another X1 sale or at least a price drop to below $200. It really does sound like the best option for what I'm looking for.
edit: As of right now, the price has been creeping back up the last few days on Amazon. Would love to see it hit $200.
