I've been steadily changing all of my cabling to SR Tesla over the past year. Started with T2 power cords on my Ayre preamp and CDP and a T3 UHC on my Krell amp. Soon afterward bought a Teslaplex (incredible bargain and should be the first purchase before or along with the Tesla power cords).
Next was Accelerator speaker cables and XLR ICs. I agree with Dave b that the Accelerator line (when it is the only Tesla cabling in the system) has a "Gray" sound that tends to wear on you after a while. Too bad he hasn't tried Precision Reference and Apex. Totally different story, plus the Accelerator XLR IC works well when used between preamp and amp combined with the higher-line cables (poor man's Precision Reference?).
Soon afterward, upgraded to Precision Reference speaker cables from the Accelerator (big improvement). Then bought a REL Stadium III and added a REL Spec 2 hi-level cable.
Each addition and upgrade of Tesla cables and power cords was a significant incremental improvement. The only exception was when I tried a Precision AC power cord in place of the T3 UHC on my Krell amp. Although detail, clarity and air were superior with the Precision AC, overall musicality suffered so I quickly sold it off for what I paid for it.
The frequent claim that adding additional Tesla cabling (properly selected to give optimum synergy) yields a "sum is greater than the parts" benefit has definitely proven true in my system.
I recently added a Powercell 10 SE (most significant improvement yet) and a QLS9 for the MPCs. At the same time, I decided to demo an Apex XLR IC and Hologram D in place of the AQ Niagara 72dbs XLR IC and T2 power cord on my Ayre CDP. As expected, the improvement was remarkable, so I decided to buy the Apex and Hologram D in addition to the Powercell and QLS9.
The demo Apex ICs and Hologram D from the dealer did not have the Galileo MPCs, but I ordered four of them with the new cables. One was placed on the Powercell 10SE/Precision AC combo, one on the Precision Reference speaker cables, one on the new Apex XLR ICs, and one on the REL Spec 2 cable. I can assure you that the Galileo MPCs in these four locations made a VERY profound improvement in the sound of my system over the non-Galileo-MPC'd demo cables.
Based on what I am hearing with the Galileo MPCs in place, I would recommend adding them to your existing Tesla ICs and speaker cables before upgrading to higher Tesla lines, just as the Teslaplex is a more sensible early upgrade than moving up the Tesla power cord line from T2 or T3 to Precision AC or Hologram without it.
I have read many posts expressing contempt toward the $400 retail price of the Galileo MPCs, and I certainly agree that $400 is a lot of cash for a "wall wart", but the improvement in my already Tesla-loomed system makes it (almost) seem like a bargain. Contrast spending $400 on a Galileo MPC for your Accelerator or Precision Reference ICs/speaker cables with the cost of upgrading them to Apex. BIG DIFFERENCE. Not that I am necessarily asserting that there will be the same improvement from the Galileo MPCs compared to moving up to Apex, only that it is a more reasonable financial step and you WILL hear a wonderful improvement with the Galileo MPCs on your existing Telsa cables. Plus, they can be used with subsequent Tesla cabling upgrades, so it is almost a can't loose decision.
Just my opinion.
