I use XLD as an encoder for my mac to create ALAC files. Works like a charm.

The only downside is that XLD is less forgiving with cds that have scratches/wear and tear on them. iTunes doesn't have that problem but I believe you do get a better, more accurate rip with XLD.
Also for you mac users, try adjusting your mini settings in Applications>Utilities>Audio MIDI Setup. You can change the Audio output for headphones or speakers or anything connected to the audio out from 44.1hz to 96hz. Also from 16 to 24 bit. Give this a try to see what you guys think. As with everything else related to audio, YMMV.
In terms of grados, I own the 225i and couldn't be happier. I also own the 80i but they don't get that much use. Did the tape mod on both and it does help just enough to add a small but noticeable leap in bass for my taste. I also own the ATH PRO500. The older version, not the MK series out now. I know most people gravitate towards the PRO 700's but the 500's aren't that bad.
One day I'd like to get the higher end models like the PS500 but it's just not in the budget right now.
