Hi,

Wow, he sure did create a beautiful web site. Being an Orpheus owner, and someone who has tried a fair amount of digital room correction, I am interested in what he is doing.

A couple of things struck me about the content on his site.

First, I think he is misstating one of the aspects of the Orpheus. He calls it a digitally controlled analog volume control. I had checked into the volume control before purchasing the Orpheus. I received a message from the Orpheus engineers a while back stating that the main front panel volume control is not analog, but a 32 bit digital volume control. In other words, it does digital attenuation of the analog output stage, not analog attenuation. Still, it is a very nice output stage that has no problems driving my Pass XA 100.5 via long interconnects. At the -10 dB setting, not much digital attenuation is needed, and I don't detect a loss of dynamics compared to a good analog preamp. The smaller headphone attenuators are indeed analog.

Second, I was very surprised to see that the picture of his Spatial software is the exact same interface of the IK Multimedia ARC system that I reviewed here a month or so ago. The ARC system licenses the Audessey Mult-EQ software but implements it in a more robust fashion regarding the number of measurements that can be taken. The software and measurement setup is very simple compared to other digital room correction software I've used. The effectiveness can range from very beneficial to almost unnoticeable depending on the system and room it is used within. I wonder if he is using the same software for room correction. It does look the same.

The IK Multimedia ARC software system ships with a measurement mic for about $500.00, and the Orpheus lists for $4500.00 but can be found for about 15% less in the current economy. So I guess the extra $2800.00 pays for the 2 terabyte drive, the crossover software, software setup, microphone location template, mic cable and stand, and remote measurement support. It doesn't appear that the MAC is included in the price.

I suppose this is a reasonable price for someone who needs support for computer software setup and room correction measurement. Still though, I think anyone who is interested in implementing digital room correction really needs to learn the measurement process. DRC systems can give bad results if not done correctly, and remote support does not allow the person who is taking the measurements to hear the results. Still, it looks like he assembled a nice system.
