In regards to the power cords, I just completed a round of comparisons with the 95 tube mod, and the 83SE with SS mods.
I added an IEC to the 83SE so the analog stage would get power from a separate cord, and PLC if necessary. But I did do some comparisons before the installation of the second inlet. The JPS Labs Kaptivator and their Digital AC cord were best out of about five cords. A silver cord and a stiff solid core copper cord were the worst. I won't mention the brands of those two. The Kaptivator also remained the best on the analog side after the second IEC install.
For the 95 with tube mods ( the mods are almost the same as the later 105 tube mods), I tried six cords on the outboard power supply, and three on the player.
On the player, I ended up with the same cord/PLC setup that is best on the 83SE : A BMI Hammerhead from player to regenerator, then a Purist Dominus Fluid to wall outlet.
For the outboard power supply w/tube regulators, the following cords are in order from best to least benefit :
1. Clarity Cable Clear Focus.
2. Sablon Audio Gran Corona (very close second). May be better with some set-ups.
3,4. Isoclean Super Focus, and Mojo Audio 8 Guage (tied but different sounding).
5. Harmonix X-DC. Good overall sound but not excellent.
6. Audio Magic Liquid Illusion. This particular cord I do not recommend for the outboard power supply. Not terrible, but it lacked harmonic richness, weight of impact, and sounded rather plain.
I have more cords here, but became very satisfied after hearing the top two above.
Hope this helps !
