Room correction - what device works best?


Looking at room correction and all the threads I found seem old. What are the current options for excellent 2 channel sound. Comments on DSpeaker, Lyndorf, DEQX, Audessy, Rives and others welcome. I have option for using in digital domain or putting between pre and amps. Would of course prefer great sound at lower price. Also prefer something that does not take a year of obsessive fiddling to get right. Have a very large family room, so room treatment options limited. Current system is Ayon Cd5s (transport, DAC and pre combined), Nuforce Ref 20 mono amps and Von Schweikert VR55 speakers. Is most of the bang for buck in correcting for room modes or is speaker phase issues also necessary? Eventually in may have subs but not now.

Al,

Yes, your speakers are truly of fine craftmanship. I've never heard them, but always found them very appealing from what I read.

Are you sure the DEQX can achieve time alignment among the drivers if you are to keep the passive crossovers in there? My understanding is the time alignment is done between pairs of channels, at the crossover points, through linear phase crossovers. Hence the need for actively amping. Maybe DEQX is different, but I think I did exchange with a user about this. At least on Acourate, I know the system can't time align if it only sees two channels as it can't delay part of the signal within a channel. This is why this decision has been so difficult to make. My system will need to change almost completely.
Thru DEQX time alignment can be achieved with speakers with passive crossovers. As it measures the response to test tones, it digitally adjusts the arrival times of all frequencies measured. So differences between drivers as well as any time arrival differences that might be produced by a particular driver itself.
Lewinski, +1 to Roscoe's response. Some time ago I had read through the 143 page calibration manual and the 36 page user manual for the HDP-4, and I found many indications of various kinds that are consistent with it being able to perform timing corrections on single-amp'd speakers having their internal crossovers in place, and nothing that would indicate to the contrary.

Also, this post by member Drewan77, who as you've seen is extremely knowledgeable and experienced with DEQX, appears to have provided further confirmation with respect to my specific application.

I know that with a regular EQ, digital or analog, any adjustments made alter phase of the frequencies adjusted. Can the DEQX get around this problem?
ZD, with respect to frequency response equalizations that may be introduced in the speaker calibration process the answer to your good question is certainly yes. I believe the same holds true for equalizations that are introduced in the room correction process, or subsequently by the user, but I can't say that with certainty. Perhaps one of the experienced DEQX users will chime in and confirm that.

Best regards,
