i'v already posted this in the HFC Forum, General Discussion under the title of "Possible Speaker Problem?", but didnt get much response. so if uv read up to here and recognise this thread, press Back... i'm changing the title so that it makes some more sense. ============================================== not sure if this is a problem, it could be the way bi-wiring works, wanted to know if anyone has had this experience: recently got a pair of KEF Coda 70s from Superfi. definitely new speakers, so not duff ones... 8Ohm impedance, 91dB and they r bi-wireable, so i got some single ended leads (QED SAs) from my amp (NAD C370) to 4 connections at the back of the speakers. nothing wrong with the sound. just seemed lower in volume than my Dynaudio 40s and they're rated at 87dB, 4Ohm and single wire. what's making this noticeable difference in volume? does this have anything to do with NAD's commutating power supply? ________ [URL="http://pennystockpicks.net/"]TOP PENNY STOCKS[/URL]
