My own personal take on such a interest, it to tread carefully and attempt to see what a system will look like down the line.
I was very eager to purchase the basics in an ample quantity to do what I needed for producing Helix Design Cables.
A hold off on the Cable Production and taking stock, showed the eagerness was a little too early. The Amp's being Single Ended were under discussion in a previous period to be changed to Balanced. The Room with Audio Equipment is not to be permanent, and the same layout will not be in place if I remain in the Home with the main audio system. A New Space to be created outside of the home, is looking likely to become the Audio Room/Entertainment Room.
Today, the Amp's are Balanced, another Valve Power Amp is also in use as well, a selection of Speakers has materialised and the Planning for the changes to the home are close to being approved by the local authorities.
If I were to produce Cables under eagerness to solely experience them in use, as a comparison to Cables already proven to be improved over other options used, I will have ended up with a selection of Cables that might not be usable as a Length in the upcoming set up for the audio system.
Another important personal lesson learned over time, especially as a result of doing a fair amount of time doing investigation and follow up comparisons is that:
"Comparison is the thief of joy"
With the Outcome being only a little extra is a possible end result to be attained.
I have over recent years, once the A/B Comparisons are done, encourages a slightly longer period of replays of an Album as the parameter for the A/B.
The Outcome is nearly always the same, where the listener after having listened to the Album for a extra period of time, does not show too much care if the alternate is set up to be replayed.
The extended listening allows one to relax and enjoy, why change that.
Whether a Bass Note decays speedier or a Vocal has a little less sibilance is not a concern raised. Usually comments made are quite different, such as, "I forgot this Track was on this Album, it is a great Track".
