Small difference equating to a big difference?


My system had started to sound a bit dull and lifeless to me ever since I put in some blue jeans interconnects. I'm getting a lightspeed attenuator in a week or two so I purchased two pairs of short, inexpensive interconnects with a really low rated capacitance in order to use them with the lightspeed. Anyways, I replaced a pair of audioquest diamond back rca's between my dac and pre, and a pair of signal cable silver resolution xlr's between my amp and pre amp with the blue jeans so that I could have them broken in by the time the lightspeed gets here.
Anyhow, my system had, what I thought, lost a lot of detail and "life" and couldn't really figure out exactly why. So I grabbed two pairs of analysis plus oval interconnects to demo tonight and voila, right from the first song, I had my detail and "life" back. When I a/b compared them to the blue jeans I couldn't spot big differences like I thought I'd be able to, but for some reason it does in fact sound like a big difference and I can't put my finger, errrr, ear on it. The analysis plus do have slightly more detail and sound slightly more fleshed out but the don't sound day and night different but they do; does that make sense to anyone?
At the end, I a/b compared the original diamond back from dac to pre, signal cable silver res xlr between the pre and amp to the analysis plus between dac and pre and also between pre and amp. The diamond back / signal set up had more bass and equaled the analysis plus in all other areas but for some reason I still slightly prefer the analysis plus.

I've found also that sometimes it's hard for me to give a product an honest assesment if I've read reviews on the product before I listen to it because I'll be anticipate hearing the pros and cons about that product before I even begin to listen.

So what do you think is going on here with such perceived slight differences making a bigger difference? Is it possible I'm picking up on things in the sound that I'm not consciously aware of analysing like tone or prat?

Does any of that makes sense? Absofeakinlutely. Welcome to the beginning of the high end (that is, presumably it's a sign that you're taking the sound of your gear seriously). Many a hobbyist has gone on from where your at to build some mighty fine systems by indeed paying attention to the kind of things you just outlined. In my case it has taken me over 23 years to get to that point without breaking the bank, so don't be too surprised, except possibly at how far your instincts (which seem to be on target, to me) might end up taking you over time. That bit of "magic" or "life" IS the small, but also very BIG thing that this hobby often about. Synergy might be the word most often tossed around. With IC's in general, I've found that if it relates to openness, less smearing of the sound, better soundstaging, more air or space around the instruments, that is largely an insulation thing (less is more), but sometimes there can be a system-related effect that not many but the most advanced of ee-types among us can begin to explain to us with any degree of predictability of the results. So, whenever you happen to stumble across something like this by experimentation, do yourself a favor and try to come to grips with what you might suspect are the pertinent questions to ask...even if the answer is not yet in sight, you may eventually come across it later while looking for something else. I've done that countless times over the years, but I would never have recognized the relevance of the related topics had I not taken the time to at least fathom the questions of my own in my head to begin with. IME, hifi's, like women, are often mysterious creatures that must be lived with for some time in order to truly understand and appreciate them ;)
It doesn't take much to bring out the missing elements that make music sound right.
Rrog, that may ultimately depend on just how far someone ends up wanting to follow through with that approach - the further you take it, the more technically challenging it can become...but I'll concede that everyone will define the target endpoint for themselves differently (as it should be).
Analysis Plus will do that. IMHO far and away the best buys in audio, even their basic 99$ IC's are killers.
