@M Code touched on it... I think the HTP-1 was a calculated gamble.
It's at a good price point compared to the other options out there/coming down the pipeline. Mono/ATI assumed it likely that only a relatively small handful of people would jump on this. They also probably counted on a dedicated group of power users to do things to the unit that they just couldn't imagine in the shop. Lastly, they also probably counted on the AVS thread taking hold.
I don't now what it is about the HTP-1 and other 16-channel units that seem to be so much more trouble than existing 11- and 13-channel units. Likewise, Dirac is out on the market, and it strikes me as silly that [Emo] can't get it up.
But therein lies the rub with being an early adopter, sometimes... there are kinks.
What I know, from reports on the AVS HTP-1 Owners Thread is that:
Mono has taken units back without problem for any reason... some just as silly as a user that couldn't do something his old AVP allowed him to do
Monolith Guy is a member of the Monoprice team and has been monitoring the thread actively, responding periodically, and posting updates on bug fixes and release information.
Dirac also has a team member participating in the thread.
Most of the power users are happy.
The non power users seem to be ecstatic (one in particular came from an EMO and is gushing over the HTP).
It would seem that there are only two issues that are readily holding things back and those are fixes from some minor popping coming from sources, and the gain structure adjustments.
the Bass management software is in hand at ATI/Mono and being worked on for implementation. No release date is set to best of my knowledge.
In two months, roughly, they got that device up to ~90% of it's promise.
For those that can afford to purchase the luxury Processors, which I would consider the JBL unit to fit in to at $6K, perhaps the future is bright. ATI will have a head start on the competition. Perhaps the Arcam/JBL units catch up. I know there are some outliers in the field, but for now...
HTP-1 for the win.
