Hello. New here but seriously considering buying the RTia5 floorstanders. I am also getting the Azur 650C CDP by Cambridge Audio. I have a C340 Integrated Amp by NAD connected to the variable in of a C270 NAD Stereo Power Amplifier at 120W x 2. Are the RTia5 floorstanders good speakers for the money? I have an old pair of RT400 and they work just fine but they are 10 years old and since $$ would permit me, I thought of upgrading to the RTia5 now. The specs on these floorstanders say from 20 to 250 W. Will the NAD be enough to drive these? By the way, I am also looking at the Parasound preamp model 2100 and the power amp model 2125. Any feedback on these? I spoke with someone from Parasound and he said that the advertised watts on page is conservative. He told me that if the page says 125W it would actually be about 145w continuous. Is this true? Should I buy Parasound or Rotel preamp and amp? Is there such a thing as "house sound" from Parasound and Rotel? Is Parasound warm or bright? What about Rotel?
