I usually use my laptop, xbox or Ipod touch as a source. Would I be able to hear any significant difference in the sound if I bought a cheap DAC like the
Behringer U-CONTROL UCA202?
The SQ from my iPod Touch and PC is very poor compared to that from my CDP. IMO £20 is a small price to pay for what I expect would be a tangible increase in SQ.
There is no doubt that an iPod and PC for that matter is a convenient way of playing music if the SQ can be improved.
How do you send the sound from your PC i.e. what output method and what software program and operating system?
I currently plug and unplug them. I think I may leave my xbox plugged in without the DAC, I would have thought that the internal DAC on that is probably better than the one in my ipod or the one in my laptop....
Could you do a 'sound-off' between the xbox and the laptop using the same CD to see which gives best audio? Whichever looses has the worst internal DAC.

Then your amp has a problem and is potentially lethal. Plus, it may fry your new DAC. It can't just be the cable.
It might be a trivial fix, it might not.
kevinlar said:I put this down to the cable not being insulated correctly :/ I wrapped the metal casing in insulation tape
Whether the cable is insulated or not the voltages and currents involved shouldn't be enough to give you a shock.. Your use of block capitals suggested that the problem was a significant one.
It still sounds like an earthing fault in the amp to me, but others may disagree. I am not an electronics engineer but the only times I've ever had any kind of shock has been either static, my stupidity or a fault.
Insulating the cable may help but in general equipment is designed so that it takes at least two faults before something shocking or dangerous can occur. Perhaps a failure of insulation is exposing another problem?
it isn't a shock at all, just stings constantly.
It's unlikely to be static if it is constant and not discharged by a touch.
What does this mean for the amp? Is that a serious problem?
A static charge could build quickly again following a momentary discharge
Safety Warning: I don't wish to scaremonger but, if the amp is `earthy' the engineers term for earth faults, it could be lethal if the amp is switched on and not earthed through another component such as a cdp, this is normally acheived via the screened phono connecting cable, but again must not be relied on 100%.
