Schiit JOTUNHEIM R ( the only alternative other than the Rall interface box or the Raal HSA1b which I already have on another system ) This piece of. Schiit malfunctioned as soon as i attempted to power it on .I attempted to talk to customer service or technical assistance which is impossible because this schiity company does not have any. You have to use emails that they do not answer .I. had to initiate a PayPal complaint to get my money back and send it back .This company has miserable quality control and it is obvious they do not check equipment before shipping .Normally I would take a chance and ask for a replacement item in exchange but I would never dare deal with this company ever again!!
