Hi:
Sorry it has taken so long to get back to you. Unfortunately Frank is under the weather and I needed to check with him to see how far along we are on various remote options.
We actually have a prototype unit with a remote volume control and remote mute. We have looked at the cost of adding it to the existing product line and it appears to be fairly expensive to do it right. There are many solid state options to electronically control volume, but everything we have looked at interferes with the sound quality. Naturally we don't want to do anything that alters the sound.
The best option is to replace our existing precision volume control with a motor driven precision audio control. In essence it's a very high quality volume control with a small motor that turns the knob/shaft. Along with the motor driven audio control we would need another faceplate, a new chassis design (or rework the existing chassis) to support the receiver and logic unit, and a hand held remote sender.
The cost of adding a remote volume/mute to the preamps would add a bit less then $500 to the existing cost of the preamp. At this time we are not sure if people are willing to spend the extra money. If, however, we get enough feedback from customers that they would spend the money for a remote control option we would bring the idea back to the front burner.
Thanks for your question!
