Have you ever used a separate speaker selector unit to audition speakers? Would you?

@hilde45 That’s the point catdoorman and b_limo were making.

First, you will need to find the ’workable’ / ’close to best’ placement for each speaker and evaluate each in the specific positions each sound ’best’ to you.

Second, ideally, the speakers not being evaluated should be moved out of the space so the physical presence is not a factor (for the non-active speaker).

You will also likely have your ’original’ speakers set up to your preferences and optimized via component / cabling etc. synergies based on your choices. That may not transfer over to the second and third, and.. speaker being evaluated.

Listening positions may also need to be adjusted / changed.

There is more...

It gets tricky. : )

@david_ten Thanks. I get it more, now. I'll establish placement for each speaker, mark it, and make sure that nothing extraneous gets in the way.

There are all kinds of obstacles to a perfect comparison -- how long it takes to get used to things, burn in, placement, etc. Either those obstacles are great enough to indicate no point in comparing or they're minor enough so that there is something to be learned by comparing.

I'm going to assume there's something to be learned and do the best I can. (I also think this will be a pleasurable experience.)

If I hear no difference, I choose on other factors. But whatever happens, I'm the sort of person who wants to go through a process before making a final decision, even if that process will be less than ideal.

@b_limo 
Sometimes you don’t appreciate or understand a speaker until you’ve listened to it for a week or two.

Agreed.

 

in most cases, for most people, sonic memory is good enough, long enough... so that no switching device is required.

If you find that you can’t tell the differences between the two, unless you had a switcher for instantaneous switching, then they are close sounding to one another.... close enough that it’s in the ’six of one, half dozen of the other’ kind of category.

I submit that your ears, and recall... are very very likely to be good enough so that there is never any switcher required to get this sort of decision off the ground, after a few back-and-forths....

In many hundreds of speaker comparisons, I’ve never felt a need to arise for a switch-box. As 99.99% (of course that is an exact percentage! right...) of all ’different models and brands’ of speakers are so different, so obviously different, that no switcher could ever be of any fundamental use.

If I was tuning crossovers as a comparison to the original lab calibration sample speaker... THEN a switcher would be... quite possibly... critical. But then, burn in of the production sample vs the lab sample rears it’s head and you’ve got a difference and a mess again.

Yes, one possibility here is that I'm just stupid. But another is that you tend to rush through experiences or don't pay enough attention to realize they are complex. To a gourmand, all food can be gobbled up quickly. But I've read other comments you've made in other places and know that you are a careful listener. Why not draw on that experience and contribute something you've learned to this topic rather than finding a way to demean the question -- and the questioner?

Pretty sure you meant to say glutton. A gourmand will take his time because he enjoys eating. Gluttons gobble. Gourmonds savor. Just a little too much is all. 

All you have done is buy into the same evanescent memory trap as so many others. Its easy to do- at a keyboard. The minute you step away from the keyboard, and actually go and listen, that is when you learn what is what. Once you do it blows the blather away in an instant. 

Like if you read back far enough in my posts this will be about the third or fourth time relating this, the story of back when I believed the evanescent memory blather. I drove 200 miles to where they had just the magic switch you seek. Because surely whatever slight difference there might be between interconnects had to be so miniscule no one could possibly be sure or remember unless switching back and forth fast and often. 

When I got there the magic switch was broken. I had driven 200 miles. Okay I will try without the magic switch. Listened a few minutes to their wire. Okay, pause, put mine in. Instantly, and I mean so fast I hadn't time to sit down, it sounded like I broke the guys expensive tube amp. I could hardly believe. My wife was there too and she could hardly believe it herself. 

There's a million things to say about how to listen. But really its not how to listen, you already do that just fine yourself. Everyone does. Only reason we're here is a million ancestors heard the twig snap and froze or hid or ran or fought. But they heard the twig snap. So you hear just fine. What you need is the language to understand and describe what you are hearing. This you only learn by actually taking the time to listen and compare. Which sad to say cannot be done at a keyboard. 

The differences between interconnects are obvious and easy to hear. The differences between speakers are obvious and easy to hear on steroids. 

Go and listen. You will see.
