I will be doing the upgrade, just trying to get the money together. I just dropped almost 2,700 on two more RF-7s and an RC-7 center. I will be buying one more RF-7 for my center when we buy our house but for now the RC will work. I want all four RF-7s upgraded, I'll pass on the RC since it will be sold in a year or less.
Oh btw, four RF-7s in the house bring a smile to my face everytime I listen to them. Soon I will open the door to tubes.
