Can anyone sugget a good DAP player for an advanced classical musician crippled by extremely developed ears and brain function. I require accurate sound but also will dip into RAP where I would need some accurate and deep bass. Budget puts me under $1000 and I would like some decent internal storage. Reviews are often talking about case and looks which is not where I'm at. I need the best audio quality at this price point. Also suggestions for compatible closed headphones (for travel) would also be greatly appreciated. Looking for personal listening comments rather than endless specs. Many thanks to you all.
