Would the Loki be of any help in trying to fix bad room acoustics (too much bass because of speakers being closed to the wall)?
Of course, the Loki cannot do anything about fixing your room, but it definitely can attenuate the bass as this is one thing the device is designed to do. Personally, at a price of merely $149 I'd think of the purchase as "hard to go wrong". Besides, I'm pretty sure (not completely sure so by all means ask Schiit) their 15 day return policy applies, so you could try and if not to your liking, you'd be out around $20. Only reason I don't have one myself (but I do have other Schiit gear and have positive customer experience), is there is no XLR connectivity.
