My current setup is a Rockboxed Sansa e260+microSDHC, and I'm happy. BUT, I heard that I might be sacrificing sound quality. If so, I need to upgrade. My requirements: -If I can't expect a serious upgrade in SQ, I'm happy as-is. -No HD players less than 40G. The 32G SDHC cards are coming out. -Rockbox, or EQ/audio tweaking of comparable quality. Don't need video. (On those screens? Please.) I like battery life, but I'm not rigid over it. AC adapters are nice, but this will be mostly a mobile unit. I use IEMs, so I almost never amp. I'm thinking <$300 USD. I don't mind paying more if quality is commensurate to price. Sound quality, that is. I don't care for pretty bells and whistles--a battered stainless steel cube would do, if it sounds right. So, should I go shopping, or is it Sansa For Life?
