Rebbi, yes, room, but also IC's & speaker cable. Monster can be a bit compressed, especially if its the cheap stuff. Audience has some good value cable. The IC should run you used @$220 and the speaker, well, I can't remember. If you can sometime, think about some of Audio Note Kondo's copper entry level speaker wire: @$500-600 for 8ft pr.
I like the Arro, nice little speaker, but, as I said, I would have tried to scam a Model 1 used for about the same price...that said, the Arro should image well; that's what all Totems do well.
