Just bought a new, unopened ipod 5th Gen on ebay for $249.00.. It seems like the older the better..The new ipod classic 7th gen has Cirrus DAC's.. So I first got a use Gen 5 from Game Stop. I could tell a big difference in that and a Gen 4 ipod touch and iphone 4s. With the EQ set on Rock mode. The Gen 5 sounded awesome.I the ipone 4s and 4th gen touch, the sound went way down and the highs were cut out! That was going from Fla to Rock mode on the EQ! So I bought the NEW unopened gen 5 form E-Bay! I ipod I got from Gamestop, had a bad headphone plug.. Music wouldn't play..Would hear a skipping sound in the headphones. When connected to a Music Dock, it worked fine! I have a Logitech s715i..It sounds great! I also just ordered a iHome iP1 Studio Series Speaker Dock for $149 on Amazon.com! That's a great dock with great speakers that have soft dome tweeters! Anyways..Hope this helped with picking out some good mp3 players! Newer isn't always better!
-Enjoy the Music!
