Speakers versus Balance vs Amplifier

I’ve been leaning towards a Pass amp to try the magic of Class A but couldn’t commit to an amplifier without a “balance” adjustment. Love the reviews of the new Int-60. 
 

Yet, when I listen to my Mc 252 through my SF Olympia IIIs, I find the “balance” feature is NOT the same as moving my seating position to the midpoint on my loveseat. I always sit on the right side and try to “balance” the sound by increasing the left side volume. 

Should be good, right ?  Most definitely not !!

But, If I just shift my body 15” to the left, center if the of the loveseat, ALL manner of magic happens . . . the music and singer are now right in front of me . . . wide, deep, tall . . . amazing !  No sense of sound on the right or left . . .  mostly just right at me !

I cannot achieve this effect with the “balance” adjustment and I’ve been trying for 4+ years ! ! !

So, maybe I’ll try the Pass amp, forget the balance control and just sit in the middle!

And, yes, I’ve had the speakers and JL subs toed in, straight, toed out, baffles aimed inwards, aimed outwards, etc, etc, etc  

My seat is about 8’ back from the amp (in the center) with the speakers about 5’ to each side !

I guess Nelson knows “balance” adjustments controls just don’t get it . . . . center listening position does ! 

So, do others agree or am I just not smart enough to use the “balance” control feature.

All feedback welcome  BTW, tonight, 54 years since first listened to, I find the musicality of AquaLung still awesome !  The louder the better . . . being 72 still has its benefits . . especially when you’ve got the house to yourself !

Thanks for reading this ramble !

I agree with the OP. Long standing, peer reviewed science tells us that the ear/brain system uses both phase, as well as volume, to determine location of a sound. Changing the volume of one speaker vs the other only addresses the volume. You must be seated equal distance from both speakers in order to perceive a solid center and good stereo image. If practical, move the loveseat so the right side is centered.

 Addressing side wall, ceiling and floor reflections is often a good idea so as to reduce late arriving reflected sound from making the brain have to work harder to enjoy the stereo image.

I realize I am a member who has been remiss in posting photos of my humble room/system. Will address soon.

My first thought was about room acoustics too.

OP,

I think you get it. The sweet spot is the sweet spot, and it is in the center between the speakers. It is way more complicated than just boosting the power on one side. If at all possible… sit in the center. I have owned Pass amps for nearly forty years. The most recent have significantly improved in rhythm and pace. They convey more natural detail than Mac. You are likely to be very pleased.

OP. FWIW. I misread your post. I now realize that your reference to 15" was to bring you to the center, not 15" off center. The 49ers and the Eagles lost today too! :-)

I would measure each speaker from the seating position one at a time and see what you get. REW is a free software package. Just look it up. You will need a mic.
