My room size is about 14'W x 20'D with 8' Ceilings. My current choices for pushing these speakers is not great. My largest amp is a McIntosh 2105 with a C26 Preamp. I have few older receivers that I've had recapped and restored over the last two years while getting into this audio hobby. I have a Marantz 2285, 2270, 2265B, 2245 and a Fisher 500B and Fisher 400 as well a MAC 1700. My ultimate goal is towards a system such as a McIntosh (2) MC275 as I would like to stay with tubes as the Fishers at this point produce the sound I'm looking for. I started looking into Infinity speakers once I subscribed to Paul McGowan's youtube channel. His philosophy of speakers first and then building from there is why I'm considering QLS-1 speakers even though I know they are power hungry. I'm currently using JBL L100, Polk SDA 1, Pioneer HPM 100 and Polk Monitor 10 speakers as my go to choices. Can I use these speakers with the setup I have until I can get what is necessary or am I barking up the wrong tree? Should I stick with speakers more efficient and less power hungry because of my equipment. I'm mostly into rock and heavy metal although I don't need to play it loud and blow my hearing out at all times. I know my music is not critical listening but would love to get the most out of it and have always been intrigued by the Infinity line. They look amazing and have quite the following as well.
