Running a one man shop like this can result in a million emails, especially from audiophiles. Constant nagging questions and queries. If you let it they can really overrun you. In my experience Justin is very responsive when it matters, such as changing your order, and pretty good for general queries on groups like this where he can answer many people at once. But everything else is probably purposefully dropped.
So if you're expecting customer service via email or whatnot you're not going to get it, his model looks like he puts that effort into the builds, which is a proper allocation of effort IMO. At any rate anybody coming to this board should know that's the deal, so the constant discussion isn't really helpful either I think.
