I gave it a go, was very interested in it, but unfortunately I didn't notice anything special....am actually quite disappointed about it.

At least there is a very simple way to give it a try, especially for me as my computer skills are very limited indeed.

trouble is, the barrier method is so 'foolproof' that for the life of me I can't think of anything that I could have done wrong

When have a bit more time I'll try again I suppose, but have no high hopes this time (which may be a good thing!)

It took a little time for me to get use to it. I was so used to the triangle setup. I had to switch back and forth over a period to unlearn the commonplace configuration. The main reason it sounds better to me is, my ears are more convinced there is live music in front of me now. This is especially true for width and depth. Every other system I listen to sounds like music on a flat pane with no 3d feeling. I am at point now where this is more pleasing than doing a million tweaks to to system components.

I totally agree with you. I'm using a dsp, not a barrier, which makes life much simpler. I'm just shaking my head when they are talking about "fidelity", and "reproducing what is on the record" in stereo reproduction.
Also don't forget about the ambience channels, at least as important as the XTC.

That was my experience as well. The phisical barrier occupies a lot of space and takes a while to get used to. And it is such an uncommon set-up that for a while you keep switching back until you realize that, yes, 60 sounds unreal and creates listening fatigue over extended periods. From then on you dont look back.

fcserei: what dsp xtc do you use? Id like an inexpensive or diy hardware xtc-I know tact and lexicon produce expensive stuff- to replace my present physical barrier in the future.

well, that all sounds promising ie the time factor involved.

When I wrote my little post earlier, I didn't mention it but it was in my mind as I typed, my physical barrier was very much jury-rigged, even to the extent that I physically held one end of it up whilst I leant forward close to it. Not very conducive to long term evaluation. To be honest though, the terms usually used to describe the difference -amazing, significant etc etc all the usual audio descriptions, (my favorite) veil lifted- seemed to indicate a night and day difference that that would not take long to find. Perhaps that is wrong and I'm curious enough to give it another go.

So, as a sort of survey, how many of you are (still) using physical barriers??

Fcserie I hope will get back to us about the dsp he uses. Fc, did you start off using a physical barrier and then move to DSP?? and if so, was the only reason one of convenience/appearance or whatever, or was there a significant sound difference/improvement as well??

I believe he is using the Yamaha yss901 chip, which I can't seem to find anywhere. I was trying to figure out what equipment ever had this chip so I could obtain it that way. Is there any diff between the 901/901-E/901-F? I came up with all three in searches.

I got the xtc cancellation to work for me from the ambiophnonic website. Mr. Glasgal and Miller were very helpful in emails helping me to configure it. I think the barrier sounds much better. There is probably some way to get to a point where the pc sounds better, but the barrier is so much easier cause I don't have to fight the pc with 4 soundcards in it. I also like not having a pc on.

I've been waiting for some units to turn up on ebay. I am a little confused about the front relection speakers. Are they a different signal than the rear/side reverberation? Is there just diff modes on these units that just allows you to configure between reverberation and reflection?

I use a yamaha ax1 hall effect for ambience. Ive tried jvc-xpa1010 but it was not good enough. The ax1 is so good I just bought a second unit so I can have 8 ambience speakers as advised by Ralph Glasgal. In my experience ambience should be 15db below the main speakers.

The front ambience channels in the ax1 are different from the rear ones. They basically provide early reflections.

indeed the sound can be compared to externalised headphone sound, like being immersed in a soundfield

some like it and some don't

I like it, it is much more realistic then conventional stereo

instead of using an impractical physical barier one can try "Stereolith" or "Beveridge" positioning with nearly/equally impressive results (but "Stereolith" positioning is VERY recording/loudspeaker/room dependent)
