Post Subject: Message from dcPosted by joaco on: 12/2/2011

Hello all , i know this topic is almost about pp experience but since im experimenting with electricity i like to share some thoughts here . I builded a dac using very high quality components . As you know the power supply is critical . So i decided to use dc from 24 ( 2 x12v) volt batteri and listen to changes , i now assume dc from that battery is like very pure electricity from ac , regardless of what element one need to purify it . So it is not just the noise that become quieter , the istruments feels different , feels like they are tuned now . So i was wondering that pp working from battery might have the same effect , or similar effect and when connected to ac , noise must become part of the circuit somewhere . Anyway I will build another power supply , this time with a much larger capacitance to see if theres some effect with same voltage but much more capacitance . It seems very difficult now to feel the instruments the way they feel with dc . I think lower level (little signals) are very sensitive to noise and one must take care from the lower level signal up to the amplifier , i do not know what effect may have pp when connected to ac in the lower level signal
