Wow - all those boxes! My HK990 does all this in a single box! And EQ's 2 subs individually.

Wow - all those boxes! My HK990 does all this in a single box! And EQ's 2 subs individually. yeah but is it good as dirac live ? I'll let you know when Emotiva builds their own version of the HK990 - if they ever do - and I hope they do. I'd be very interested in that. The really trick thing about the HK990 is I can leave the EQ on when in processor bypass to equalize the two subs when using the HT stuff. So any processor I might want to buy doesn't need to be able to EQ two subs. It works quite well. But where the HK990 shines is in two channel. I don't understand why so many audio enthusiasts want the best possible room correction for HT but are adamant about not wanting ANY room correction for two channel. If their setup is like mine, and most are - a hybrid setup - they are dealing with the same room interactions for two channel. Why would you not want room correction for two channel? Now that I've experienced two channel room correction I don't think I want to go back. The sound difference is quite notable. And for the better IMO. |

Let me step back a bit to discuss a few things. I am of the opinion that even a 2 channel system benefits from having sub(s). I designed my 2 channel system from the get-go with that in mind. Knowing that I would have subs, my DIY speakers were designed with a very limited -3dB point of around 60-70Hz. Wow! I agree 100%. You are one smart guy Chuck. Is it in the name Chuck by any chance? I frequently mention this to friends and catch nothing but flack. They think subs are for only for explosions in movies, they think the center speaker is only for dialog and the surrounds are only for rear gunshots. Take Care Chuck, Chuck!  |

Chuck,
From what I have been gleaning in my research on the internet, there are several software applications for doing the Real time analysis (REW, DIRAC, Dayton Audio has software for use with one of their mics, and Acourate DRC as examples). The cost of the Dayton Audio, Acourate, and Dirac software are all roughly in the same price range ($300-$580 for 2 channel correction analysis). The real issue for a modern audiophile digital 2 channel set-up (playing music from a PC) using an audiophile DAC is the implementation of the EQ correction and impulse correction for playback. The question to answer for the software is can the correction transfer function be done for music playback in the PC or via another stand alone device in the digital chain between the PC to the DAC? I have been been having a hard time answering this question. The only one I am sure can is the Dirac software. REW can't, and I am not sure about Acourate or the Dayton Audio Software. (If I am wrong please anyone correct me.)
The Mini DSP DDRC-22D is $899 which is the device, plus the Umik-1, and Dirac software. It is basically just the Mini DSP Open DRC-DI ($299) plus the cost of Dirac software plus the cost of the Umik-1. It seem that it would just be simpler to buy the Dirac Live software for 2 channel, and leave the Mini-DSP out of the chain. Then your audio playback chain is the PC directly to the DAC then analog out. I think this may be the direction I will be going for my 2 channel set up. I am waiting on a UMC-200(to repalce my UMC-1). For the UMC-200 I will likely use either Dirac Live and/or REW, to get measurements and proposed correction EQ and manually configure the Parametric EQs of the UMC-200.
The only reason I could see going for the DDRC-22D is if you are going to run any additional digital audio sources other than PC audio through the audio chain.

Yes, the DDRC-22D runs on the same platform as the OpenDRC-DI which is a PEQ version.
Here are the prices:
OpenDRC-DI $299
DDRC-22D $899
Dirac Stereo For PC $529
The cost of the DDRC-22D is very close to the combination of the OpenDRC-DI + Dirac Stereo For PC. Or in other words, Dirac is responsible for about $500 of the DDRC-22D cost.
Microphone cost is not included as it is needed for both.
Although I agree that a PC Version of Dirac solves the single source issue, I would rather have a hardware solution.
IMO Dirac is currently way overpriced! You can bet that it was responsible for the XMC-1 price hike!!!
