what should I get to replace what I am planning to try

What is the rationale for blaming the tube amplifier for the location of the "image" generated by speakers being "too close" to the wall?  Or have I completely misunderstood your OP?  And then to go on about speaker cables seems to be a non sequitor.  First thing to do, if the object is to re-locate the image, is to move the speakers away from the wall, even if to do so is inconvenient.  You could move them temporarily to determine whether speaker placement has anything to do with the issue.  You might also try playing with toe-in, in either direction.  If indeed you find that you moving the speakers is helpful, then you have some further thinking to do about how to rearrange your system components.  Finally, you haven't mentioned what speakers you are using, but if they are conventional multi-driver electromagnetic speakers, try playing with phase; reverse the speaker wires on both speakers; does that bring the image forward a bit?

Sounds to me like you've been hitting the booze a bit much. Your post is incoherent, to me at least. 

@newbee just a BIT much?

Yes… I get the joke about sitting in the kitchen. But what is the issue? You want a smaller soundstage?
 

My sound stage goes way back behind the wall and my speakers are four feet from the wall.. this is an asset not a problem. 
 

Also, yes, the tube amp has nothing to do with the image depth… necessarily.

The image is all in your mind.  I suggest you close your eyes while listening and problem solved.   You're welcome.  Cheers.

EASY fix,turn the system around so it faces INTO the kitchen,thus reversing the sound stage to project into the listening area.

Thanks...I thought that it was just me. I haven't heard anyone here complain about excessive image depth before, but moving the speakers would seem to be a simple solution.

@freediver +100%. 🤣LMAO!,

I strongly suggest that you sell your MILLION DOLLAR speaker stands and then put the $500K, or so, proceeds into a nice condo (with a decent non-triangular listening room).

Your first, and only, mistake was plopping ONE MILLION DOLLARS into the speaker stands.

Just think of how much contact enhancement gravy you could have purchased with that sum.

With so much gravy @ hand you could have had many "enhanced" outdoor BBQ's and also used it to attract the whales residing off the coast of where you reside in cyberspace.

Priorities, priorities, priorities...

it is thinly veiled disdain for an amalgam of topics and positions that come up now and again….

think of all the $ you could save by abandoning the R channel entirely….. 

two condo….Lord, who wants to overwinter in the great white North…. only a Swedish GF could entice me so….. but alas, they so rarely surf….

I meant it as a joke (satire of a lot of wildly confusing and deranged posts lately).

I tried to write something so utterly meaningless and stupid that nobody would take me seriously, but I guess I failed.

Sorry. 

We’re a disingenuous bunch that just wants to help. Ha-ha. I’m relieved to learn you haven’t lost your marbles.

@lewm 

that's true, I underestimated the willingness to help!
