A well thought out entry level system that you need make no apologies for. I've been involved with hi-fi since the late 50s, and what never ceases to amaze me is how brutally fast the "diminishing returns" principle comes in to play in the upgrading process. Regarding headphones--I have spent countless hours over the years blissfully immersed in sound that's totally unadulterated by room acoustical influences, at volumes sufficient to cause at least some hearing loss, especially high frequencies. Take care of those ears! I can't imagine living my last years without music. Check out the Sennheiser line. The Grados are quite good, but I personally find the Senns to be more comfortable for long periods. Enjoy the music.
