Hi ! I've been in the market of a 4 preamps unit and been looking for ISA428 or Daking or something similar. Thing is my budget is limited (like everyone says) and I've came by the Sytek which is well priced and got good reviews. The problem is, I can't have any reviews or discussion about them since 2009' I went on their website, their review links are old, the site is also old and they use gmail addresses.. I sent an email just to know the shipping delay and they answered within the hour. They seem to have a good product at an affordable price but, I kind of fear the seriousness of the company and the fact that they are kind of underground, unless it's just one guy that does it all..
