New Amp Dictates New Speaker Placement?

I purchased a new amplifier a few months ago and installed it into my system. A friend who has heard my system more than half a dozen times over the previous year and a half mentioned that perhaps the speakers could be moved closer together because he could locate the sound from the drivers rather than the speakers disappearing.

The speakers had been positioned a couple years ago where they are presently located, and they have provided a superb image with many amplifiers.

The system sounds great with the new amp, but I do notice some localization of sound. Sort of a three-zone image. It's not aggregious...typical audiophilia.

Is it possible that the new amplifier has affected the image to the degree that repositioning the speakers is necessary?
i know when i use a solid state amp, i move my speakers a bit closer....and tubes, i spead them a bit.....nothing dramatic though
Yes, a new amp can make a change in the speaker location beneficial. HOWEVER, before you start playing "Waltzing Matilda" with those big boxes (I realize its relatively cheap and easy to do, but it can be frustrating as well) think about the possibility that your notice of some localization of sound may be due to the amp, or more probably the tubes you are using, than the amp/speaker interface/location.

FWIW, I went thru this with my Tylers - I was getting some piano notes, along with other instruments such as the clarinet, sticking out like sore thumbs in the upper mid range. A very narrow range. Initially I thought it was the Tylers, then I blamed the amps, ultimately what I discovered was that the utilization of KT88's in that particular amp (not in my other amps though) that was causing the problem. Put in 6550's and the problem went away. This also applies to small tubes as well. Now if you have changed your input tubes and no matter what kind you use it still is a problem then it might be your speaker location. Might be. But I'd be more willing to bet it was a speaker/amp interface problem than anything else. JMHO. Hope you can work it out.
The issue isn't so much presence of one frequency over others as it is left, right and center localization. Also, it's not on all recordings, so I might be over analyzing this situation.

I have changed input tubes in the amp without much change in the localization of sound. The amp has SS output.

BTW, this isn't the first time I've dealt with this with these speakers, so it's not necessarily the amplifier's fault. As you say, Newbee, it's likely the interface.

I'm interested to know who else has heard this phenomenon and gone through the process.
After some burn in it can change too.. but yes every component I have replaced caused a slightly different image, and moving the speakers anything from a half inch to a Half foot can recorrect it.. Last one that was weird is I changed my speaker cables and things sounded much tighter, but kinda disconnected, Repositioned the speakers and they opened the stage even bigger than previous.. same with Transports, Cartridge Loading on turntables, etc... They have all effected the best toe in, listening distance whatever in my experience.
Ah, a different issue than your initial post suggested when 'your friend could localize sound from the drivers', usually a problem associated with speaker design.

If anything is 'wrong' and you're not just obsessing, I would suggest that it might me due to the, for lack of a better phrase, the density of the information, between your new amp and the amps you are accusomed to. I would suggest you could do things to resolve your problem (much as Jaybo suggested). First I would play with toe in a bit thinking that perhaps that the previous amp(s)were a bit different in the highs and getting the right high frequency info would get you a unified soundstage, or if that doesn't work, 2)close the spread of your speakers a few inches. Just a thought! Oh, if that doesn't work you can go back to some really basic things like reversing channels to see if it the recordings or playback components, and even moving your listening chair a few inches left or right, etc.

At the risk of being offensive (and I'm always ready to risk that :-)) I bet you are too influenced by your friends observation and have become obsessive, but have fun, thats what this is all about. Been there, done that!
I'm having a similar challenge with low end presence after making some changes....have good tonal bass, just no slam of any kind....
I have played with toe-in. I'm going to bite the bullet, remove the brass footers, and move the speakers a bit closer together and then play with toe-in again.

I second Newbee...this sounds ever so unlikley. It is not unusual to notice new things about a recording even after having heard it many times does not always mean there is a problem/fault somewhere just you listened in a different way with a different form of concetration....but like a red spaghetti sauce spot on your shirt after lunch - the more you look at it the bigger or more obtrusive one thinks it is ( others may not even notice ) - out out dammned spot!

Once you notice something and know exactly how to listen for it, naturally you notice it more often. (Probably not what you want to hear - apologies if this sounds trite)
How about a new house? Tell the wife you need a special room for the new amp.
Keep my name out of this.
I have a nearfield set-up...basically an 8 foot equalateral triangle, give or take a few inches. I think the sound is phenomenal when I get even closer to the speakers...say within six feet. The speakers totally disappear.

Anyway. I moved them closer together by about six inches on each side, and I'm playing with toe-in again by trying less toe-in...essentially flat. I'll go from there.

Gotta tweak something! Can't just have a system that I turn on and play! That'd be too easy and against the Audiophile Code.
If you have anything reflective (like a TV) between the speakers, throw a blanket over it.
Tvad, Lets get that angst level a bit higher!

In my room, my speakers/listening position is triangulated at about 9 1/2ft and the speakers totally disappear, I don't need to get any closer to replicate a nearfield experience. Man you've got to work on that room!

The room is fine.

I've adjusted the speakers a little. Things seem a bit more coherent.

I'm moving on. Thanks for all the input everyone.
