Very impressed by the sound quality of my new 7G nano but of course the capacity is too small for my 45g of itunes music.Im thinking of buying a refurbished Ipod classic 5.5 from Ebay but I dont want to give up sound quality.Will I hear a big difference between 7G nano and 5.5 classic?I will be using new Apple Earpods that came with 7G nano.
