Pure Audio Project Trio 15 - Silversmith Audio Fidelium internal wiring upgrade

I heard the PAP Trio at the recent Capital Audiofest and the speaker cables were the Fidelium cables.  I have no idea if the internal wiring was also Fidelium, and even if it were the case, I would have no idea how tis affected the sound.  All I can say is that the entire system at the show was one of the best I heard at the show.  That being the case, the speaker cables had to be pretty good, at least in the context of this system.  

If a speaker builder offers a cable upgrade, you can expect that the particular cable chosen works well with the speaker (at least in the mind of the builder).  If you like the PAP sound overall, you can expect their choice of upgrade to be good.  I have some experience with a local custom builder and have heard the difference the internal cabling choice makes as to the sound.  One can easily hear the difference so it is quite important to upgrade to quality stuff.  The particular builder likes Audio Note cabling and uses different cables in their lineup to tune the sound to the customer's particular taste.  Even the choice of cabling to just one particular driver is something that matters.  In one particular speaker, the chosen wiring was a cable that costs close to $20k for a stereo meter (to the midrange driver), but a less costly run of cable to the tweeter (cheaper cabling chosen because the builder actually tried the same ultra expensive cable but could not hear a difference when cheaper cables were substituted). 

In short, I am saying that internal cabling matters quite a bit, so i expect the PAP people would be choosing the right cable to improve the sound of their own speakers. 

I just ran into a video posted on another audio website that describes an audio system with PAP Quintet speakers with the upgraded Fidelium wiring which was describe as "not a subtle upgrade."

Since you are looking at alternatives to upgrade your Trios, at some point you might want to experiment with different capacitors in your crossover.  I know a custom builder who makes some quite expensive and nice sounding speakers and amplifiers and he tunes the sound to his and his customer's liking with choice of capacitors in the crossover.  He particularly likes vintage paper in oil caps from the likes of Western Electric and Aerovox, but, he also uses modern film caps from Audio Note.  I've heard the difference and it is quite substantial.  What he really hates is the sound of Mundorf caps--he finds them to be dry, analytical and unpleasant.  He can hear them when they are employed in amplifiers too and does not like the sound.  He also employs different internal wiring for tuning the sound. 

The thing that is missing in most speakers these days that is so critical to getting a speaker tuned--to the taste of the owner, to the room acoustics, and to the other gear in the system--is an L-Pad for adjusting the level of the drivers.  It is crazy, to me, that designers think they have got it just right for every circumstance.  I think adding an L-Pad would be another step in upgrading the speaker.  The Trio I heard sounded really good, but, I bet it could have been made more to  my taste with such control of driver levels.  My speaker came with level controls for the midrange and tweeter, but, because the midrange control only allowed for three setting, I put in an L-Pad instead and it is really useful for tweaking the sound.
