possible incorrect wire connection when using the SS amp causing an out of phase image?
There's a possibility.

Those who have followed my comments for awhile may know that I'm a huge fan of near-field listening. Occasionally I've listened as far away as 80" from the plane of the speakers. Now, for some people, that would be "near field." Usually, however, I listen much closer than that.
Some folks smile or make fun of this preference for near-field listening, as if this is somehow "unenlightened" or something. Well, they are at least correct in that it does not work well with many speakers, especially those with a lot of drivers strung out vertically and/or horizontally across a baffle with a multi-way crossover. Most speakers, including these, are designed to be a quasi-point source (some are more quasi- than others!) in which inter-driver coherence is best only from eight to ten feet (or so) away or more.
By "inter-driver coherence" I mean whether or not you can hear out the individual driver positions when listening to the speakers--can you hear the individual drivers as individual sound sources or not. If you can hear individual drivers, you are sitting too close to allow the sound of the drivers of that speaker system to blend properly.

But if you're the type of person who likes to sit right down front at concerts, you are a prime candidate for appreciating this experience. And if you're seeking a level of aural and emotional involvement and immersion from your two-channel system you thought was not possible, you should try it. Just mark the chair and speaker positions you're using now. You can always go back to your "normal" set up.
Me, I'm not looking back. At least not until I look around for surround sound.
Due to the fact I have a small audio room, has meant I must listen in the nearfield. I have used this and also the cardas website for nearfield positioning - they mostly advocate a near front wall set up with loads of space behind.
I tried this approach and it resulted in a nasty dip at 97hz - its' the first image.
I then came across this article:
https://nsmt-loudspeakers.com/Nearfield-Placement
I tried to look up Leo Massi but sadly he is now deceased (i found out on an obituary page)
It advocates a mid room placement with ones head close to the wall.
I tried it and the results are superb - see the second image - yes a bit of a dip at 150hz.
I am minded to plug the ports (i have readings for that) but this was initial rudimentary tests andd I am pretty pleased so far.
I must say that I have ribbon tweeter speakers that are very smooth and high resolution (Roksan DArius S1's) the Ribbon really helps in minimising wall reflections - which I consider may well explain why Tensor speakers are becoming so popular in studios.
I now need to figure out what type of diffuser I need.
That's an interesting paper
I also have a small room and listen nearfield. The speakers tweeter is 4 & 3/4 ft from the front wall with the listening position 5 & 1/2 ft from the back wall in a 14 1/2 ft room. Distance to the tweeter is just over 6 ft with the tweeter 45 cm from the sidewall.
The balance changes as I move the listening position forward or back, a case of preference rather than right or wrong until against the back wall where bass becomes somewhat lumpy and less resolved. I ended up with this arrangement after much experimentation in the room, all tuned by ear rather than via measurement.
What I've never tried is anything as extreme as proposed here. I say extreme as I've never seen or heard of recommendation like this before.
From a listening perspective what do you hear? how does it affect imaging and tonal balance? Are you using traps in the corners as recommended?
Give the bungs a try, I needed them when I first set this room up. As I got to know the room and experimented with position I found I no longer needed them and the system sounds more natural without
So am I, while realizing your OP dated back from 2010, I believe near field is as good a solution as ever.I'm a huge fan of near-field listening
Dear TMallin.
These days I'm back to 60-degree separation. While 90 degrees is great for the best recordings--those using Blumlein or other quasi-coincident mikes as the main mike array, over time I concluded that 95+ percent of recordings just sounded too "pulled apart" with that much separation, resulting in audible "holes" in the staging.
These days, rather than a strict Rule of Thirds speaker and listener placement, I have more or less standardized on Cardas placement for the listener and speakers. This combines what I hear as the best imaging and staging for a stereo pair and bass which is fairly easy to electronically equalize into submission. See this page for the Cardas calculator for a box speaker, including the listening position with respect to the wall behind the speakers.
Thanks again. I had a pair of large Advents as well while I did one year of law school but then decided to go a different direction and got a Ph. D. after teaching for awhile. No photos of my Advents unfortunately. Regret selling those but maybe they weren't as good as I remember.Yes, the AR-4x is that size. I have no experience with the KLH 17, but the AR-4x was the first component speaker system I ever bought back when I was about 13 years old and the 4x was then in current production. I bought them again decades later as vintage speakers and used them in my office for over a decade until I retired at the end of 2022. They are good--very, very good, probably the most neutral sounding of all the vintage AR speakers, just with less bass extension but a very pleasing-to-me balance.
For a picture of that office system with the AR-4x speakers, see this link.
