My experience with RCA is similar to what the others here have stated. They utilized a lot of circuitry to maximize their set performance. All three of my ten-tube RCAs receive and sound as good as many other sets that have more tubes.
My 10T-1 on bass boost has comparable sound to a console set.
RCA did tend to apply higher than usual plate voltage to their output tubes. You will often encounter 385V on the plate of a 42 or 6F6 per the RCA schematic. With the higher house V now in use, this means that you really have vic 400V plate. This contributes to higher performance but also shortens tube life.
