With this player pretty much the sky is the limit but the mods that give the most bang for the buck (IMO) are as follows.
1)Superclock and superclok power supply are the first mods I would make.
2)I would do the analog output stage
3)Then the power supply.
First you must pick a reputable modder......unless you are doing the work yourself. Reference Audio Mods (RAM), Vacum State Electronics(VSE) and Audiomod(Richard Kern) all have excellent reputations and experience modding this player. All three have websites discussing their modding techniques and philosophies. I would read them as well as some of the discussion threads on this site. Also there location may make a difference as shipping may be an issue as well.
Good Luck.
