Anything new with digital room correction?

Mmike: It's true most CD players have digital out--but in that case where will you do the D/A. Most Cd players do not have a digital input. Some very high end ones do, but most don't. And I'm also considering the possibility of analog sources such as a turntable or tuner. I did not mean to imply "you have to buy new equipment." I was only trying to point out some potential caveats. That's to say there is one and only one way to accomplish the goal. It's more a matter of helping those reading this post to define their goal and then what approach might work best. Obviously, it's not the same answer for everyone.

Rives-

I was assuming Sashav has a preamp with phono or if not, and he needs it, he could add a separate phono stage. Your last post says most CD players don't have a digital in but I think you meant out which I don't agree with. Most high end one box CD players do have a digital out, and a high end transport would work even better. While it's true the D/A conversion has to happen somewhere but in the case of the Lyngdorf room perfect system the unit has an excellent D/A in it.

Thanks for clarifying though (and responding to my post!) as I felt your first post suggested Sashav would need new equipment and should abandon digital correction which may not the case. In the end I strongly suggest keeping an analog or digital source as far as possible. Thanks for clarifying. I think we're both making useful suggestions so Sashav can make the best improvements he can. :)

Sahav says, "Yes, I have a couple of nulls above 100Hz, but not exceeding 3-4dB."

How do you know this? How do you know what is happening in the lower freq (20hz to 100hz)? Just curious.

Mike--I actually did mean digital end. My point was getting a really good D/A conversion. You are right most CD players do have digital out--but my concern was where will the D/A conversion take place. If the CD player is a top shelf unit you wouldn't want to just use the digital out and convert D/A with something that's not up to par. What would be pretty nice is if you could go digital out to a really good digital processor and then back to a top shelf D/A. This would work great if you used separate transport and DAC or in the rare event the CD player did have a digital in. However, this obviously limits the sources that would be corrected.

Acoustat6,

I measured it using TacT.
