It is a frustrating situation for both Involve and the customers. You have to make business decisions and we have to make purchase decisions, both of them involving finances. I already purchased 2 Surround Masters, 1 and 2. The 3rd gave me no compelling reason to buy another, since I don't need the optical in, but HDMI out would.
I haven't been able to use either of my Surround Master's since my receiver with analog inputs died. Still saving to pay for 2 nice stereo amps or shell out for new receiver with analog inputs. Using the amps or considering the Involve 6 channel amp leaves me with no remote control pre-amp for volume control.
I really have no intent to "harass" you into adding HDMI, just giving my perspective as a customer and what some of us would like to see added to meet our needs. I really like the Surround Master and appreciate the technology you have brought to market. I also appreciate the communication and fun conversation you provide here!
