First off, I hope that whatever price the HT4's come out at, that they sell very well and that Jim continues to be successful.
Secondly, I am extremely confident that the HT4's will compete with other products costing multiples of their list price (I am basing this on my experience throughout Jim's product line) in terms of performance, looks, and reliability.
However, I am not sure how many pairs of a $10k+ speaker ANY an internet direct company can sell. Generally speaking, people who have the means and are willing to spend this much on speakers won't buy internet direct. They want to see, touch, and hear the speakers before making a purchase at this price point. You also have to take into account that many people will only purchase from the well established and known brands when spending this much or more. In my experience, it isn't just about performance and value when you get up to $10k or beyond...name recognition, reviews in established magazines, as well as being represented by established brick and mortar dealers are the major contributing factors in the buying process.
Just my thoughts...
