Marri, the Galileo Cells are sold as pairs. For speakers you will need just one but for sources you will need one from source to preamp and one from preamp to amp. My source is my dac and it has a volume control so I only needed a preamp to amp. Also the speaker cell can be bi wired. Go to the Synergistic web site and you will see the latest versions. If and when, try and go with the active versions as you will get the biggest bang for the money. You will also find a price guide and if you google it you can find an earlier one. They have posted a guide of what they plan on releasing over the next few months under the CES posting. If you can call them they are very willing to guide you for your system and budget. Try Eliot. Right now on Audiogon there are a few Power cell 4 and 10 for sale. If your budget works, go for the 10SE MK II if it is still for sale. SR is coming out with an PC 10SE MKIII as I write this. Check with SR but I believe the PC is not voltage specific, just the cord. But check as I am not sure on that one. You are right to spend your money on the GU speaker cells and use your Aluminata SC with them for now. If you can go for the GUC for the speakers and the PC 10SE MK II. Then go from there. You may find after that you will stay with the Aluminata. SR says many other cables work very well with the GUC. One of my dealer friends love Cardas with the GUC in his system.
Well good luck and post your results after you finish.
