I know they will introduce a little something soundwise,
how did you prove this to yourself?

AndrewT,

By trying/comparing troughout the years crimped vs non-crimped (bare wires) speaker jumpers, interconnects and speaker cables...

That is how I ''proove'' it to myself... Other audiophiles from Montreal were here to compare as well. Maybe some of them (members of DIYaudio) could jump in ?

Sadly, I don't have a catalog of datas that could be examine by the scientific community to accept or discard (after all the mathematical graphs have been analyzed) what I (we) heard....

Differences ? VERY VERY subtles loss of transparency and, instruments/voices becoming very slightly bigger (compare to prior sizes without sleeves). We are talking tiny subtleties but, noticeable nontheless.

Regards

Scorpion

Stocking up I see. You will write the "Scorpion BOM with notes" in the end of your experiments I presume. So any aspiring "Deluxe DCB1" builder could use it as a subjective compass.

Hi BigE

Yep...see pics above. I have Vishays Naked Z-Foil Tx-2575 at the 220R position.

Going to compare them to Shinkoh Tantalums (among others).
