It doesn't SOUND like a problem, but I wonder.....

OK, here's the deal. I had been biwiring for a LONG time in I guess whatcha call yer "shotgun" mode(?), with four two foot lengths of good 'ol Tara Master Gen2 from each monoblock to each speaker (good stuff). Not one for obsolescent dogma, and being the open-minded sort that I am (and partly because I was bored), I ran one length to the mid-bass driver and used the other two foot length as a jumper to the tweeter to assess the difference -- also because I'm switching to tube monoblocks with a single pair of binding posts and Tara isn't the most bendable, stretchable cable out there ya know. (whew, that's one hellacious run-on sentence, huh?) Result: sounds good - better overall, actually. My question is: Is it a problem at all to use such a length of wire as a jumper? Will it cause any potential timing errors or quantum tachyon phase-shifts or any other unforseen phenomena? Do I REALLY need a short-short-yet-high-quality jumper? Have I already answered my own question? Am I just lazy? ;-)
