Hi all:\n\nBasically, I want to know if the Schiit Aegir (a single stereo unit) will partner well with my Polk R200 bookshelf speakers. They are rated at 86db sensitivity - 8 ohms but from much reading online I believe they are more like 4 ohms (which would rate the Aegir at about 40 watts).\nMy living room is not overly large (I only sit about 7 feet or so away from the speakers).\nI don’t listen at loud volumes (mostly around 9 o’clock on the volume - using an SPL app, the numbers were between 73db to 80db max). I mainly listen to classic rock, blues, country and light vocal music (Beatles, Mark Knopfler, Emmylou Harris, Cat Stevens, Van Morrison, James Taylor, Pink Floyd etc. – I think you get the picture).\nI have an NAD 326BEE integrated amp (50 watts) that has a pre-amp out that I would pair to the Aegir. \n\nI'm also trying to understand wattage vs SPL and speaker sensitivity. If my speakers are rated at 86db at 1 watt, why "might" the Aegir be problematic driving my speakers if I listen at an 80db max SPL?\n\nI like the Aegir design because I believe that Class A gives an overall better sound quality. I’m looking for detail, detail, detail - without sharpness of course) Any thoughts\/answers are greatly appreciated!
