length of interconnects for passive preamp

My passive sucked the life out of my system when I was using very inefficient speakers and monoblocks, which required  3 meter ICs. I recently switched to very sensitive speakers (horns) and a stereo amp  and the passive sounds great even with the same ICs. the reason for my q was I want to purchase shorter interconnects to get it to sound even better (and the fact that I do not require this length). I will purchase 1 meter or .5 meter ICs - question is what brand - to be honest I do not quite understand the specifics of some of the previous posts but want to express my thanks and appreciation for your contributions.

Ideally we change only 1 thing at a time.

I suspect that the input impedance of the power amps play a role, and the gain of the amplifiers also okay a role.

I would purchase the cheapest Amazon cable, or what you already have in a Red/White/yellow set.
And use that as a baseline in an A/B test.

The Wonka mentioned these earlier 

Personally I would not be using anything that is more $ than that, and they are at my edge of what I can tolerate in terms of marketing foo.

It would be best if you could try them before committing.
And whether you hear a difference or not… it would be good see your feedback.

@holmz - as I said in my previous post

Granted - using as short a cable as possible will reduce capacitance and inductance

So I guess we agree ! - to some extent 🖕

BTW my statement 

• using any old piece of wire is defeating the purpose of having a passive pre in the first place

I was not quoting you,  I was just trying ot highlight the point - my apologies for the mis-use of bolded text

A better qulaity cable like those offered by Zavfino of 0.5 or 1 meter long will help to achieve your goal.

Also - what speaker cables are you using?

The speakers cables were made for me by a local tech and I do not have the specs. I will report back after I try the shorter ICs. Regarding my prior 3 meter ICs I I started with cardas microtwin, which seemed to "round out" the sound and were a little muddy,  then I changed to a more expensive cardas - I can't recall the specific model - which was a step up - and then I had 3 meter ICs made by Stephen Sank, who is a tech/modifier of equipment based in Arizona -   they are unshielded and were inexpensive - but were MUCH better than the other 2 - so I may purchase shorter ICs from him or send the 3 meter back and have him make 2 pair of shorter ICs.
