Redgum RGi120ENR integrated ?

Just ordered a Redgum RGi120ENR integrated... 155 watts per channel (ss) to use with Fritz REV 5's with upgraded drivers (ScanSpeak Illuminator 5 inch woofers and 9700 tweeters) in 12x14x9 room ... prototype not on Fritz website. Have been using Quicksilver 90 watt monos (20 years old) with Quicksilver new non-remote preamp... because of ss ordering WyWires IC's with softer voiceing rather than Kimber kcag. Quicksilvers get to warm in Arizona summers (even with air) and are about 45 pounds each. Getting old (68)... ANY OPINIONS?
