Cheers guys, I use a lot of different sources as you can tell from my sig so and the back of my amp is a tad tricky to get to plus I'm the kinda guy who likes to set things up then leave well alone incase I break something lol. Isn't the tape out bassicly a pass through so its purely the signal coming from the source anyways or does the nad amp do something to the signal? I've gotta say I'm loving the headphone amp though, it sounds a lot better and seems more clearer and better seperation plus there is more base and more control on it, could just be the placebo effect but we all love shiny new audio equipment don't we! Also won't having the headphone amp pluged into the tape out have an effect on the performance of the main amp when being used normally as it has to mess about with 2 signals as opposed to focusing on one?
