The reason you notice improvements may be due to you breaking in a new connection. On the QX5/20 you only need to break in the DAC, but on the preamps and amps you need to break in each connection. It will get better all the way up to at least 500 hours. Its' the amount of silver used in the leads etc... Crazy isn't it?
