Is it worth upgrading your Dac when you use the digital out on an Ipod ?
My present system is a Marantz M-CR603 and Dali Lektor 1's and my 160gb Ipod classic is connected via an Onkyo ND-S1 dock and QED optical cable to the '603.
My question is would I hear a difference if I upgraded to an external Dac in the £300 to £500 region or is the ipod as a source the limiting factor making the Dac upgrade pointless,the reason I'm a bit uncertain about this is that I tried this upgrade before only with a Denon DR-M38 and a Dacmagic and I could barely tell any difference between the Denon's Dac and the Dacmagic.
The Dacmagic did sound better but it wasn't worth the extra money imo.
So any opinions on this would be welcome,also any Dac recommendations.
