@lightfighter2018, I am assuming you are going to use a AV processor that calibrates the speakers for you to watch movies. That will take care of gain difference in using different amplifiers. There is no need to get same amp for LCR. Same amp for L/R yes but not LCR. The gain difference should not be large however like 6 or 10 dB most amplifiers have gain between 26 and 30. Stick to 26 area and you are good.
I a not sure where you heard about CS issues, but folks at audiocircle are quite happy with Klaus @ Odyssey, he personally responds and takes care of every customer if I am not mistaken. They are a small shop, you are looking for value for $ so I pointed them to you, everything is hand built and 20 year warranty. Real HiFi sound on the cheap. Similarly used Parasound are quite good value, they are stable till 2 Ohm again well engineered.
