Hyperfi do seem ver cheap at the moment, well, they always are! But, if i were you i would see if you can bargain with someone else to get a similar price, i have tried hyperfi befor and they employed dirty richersounds tactics on me!
Well, they were good as gold with me. Kept the items on hold till I found the C4C I needed then had them sent next day delivery at no additional cost (and there were lots of BIG boxes - everyone one double boxed).
Haven't set them up or connected them to anything yet as still planning the HC room but they sure look good
