Longer XLR Runs

In over 25 years of this High-end Hobby I have never used or experimented with an interconnect run of over one meter in length. I have a want not need to move my source/preamp about 3.5 - 4 meters from my amp. I would use XLRs for obvious reasons (gain,etc) but my question is how much will this affect the dynamics or sonics in general? I certainly don't want to jeopardized those for any reason. I could do longer speaker runs which I have done in the past with good results, but I want my amp in the middle so that's not an option. Any thoughts or facts would be appreciated. Thanks Chris.
i have found that long balanced xlr interconnects w/ short speaker cable is way better than the reverse. and if your xlr's are between true balanced components respectively, you will not jeopardize any dynamics or sonics.
The general thinking is long interconnects and short speaker cables. you should not suffer a loss in quality doing what you propose
I'm using 25' (7.6m) XLR calbes with excellent results. They are Bluejeans cables (Belden 1800F with Neutrik connectors.)
I use 10meter XLR interconnects without issue.
