I own the Klipsch ProMedia 2.1s, and I am very pleased. I recently purchased the $30 Monster Cable upgrade for the ProMedia 2.1s, and this has really helped the clarity and precision; it is most noticeable when watching a high-quality music DVD, such as ?G3 Live in Concert,? or ?Dave Matthews Band: Listener's Choice.? However, I have noticed even larger flaws in my MP3 collection =) The Diva Swans are nice as their transient highs are incredible, but they are not worth $200, IMHO. The new Cambridge Soundworks' MegaWorks 210D are great as well, however, they were never retailed - the 5.1 version (510D) are the best multi-speaker system I've heard to date. However since the focus of the thread is 2.1 with headphones, the best PC speaker system I've ever heard is the VideoLogic Sirocco Pro. They are simply unrivaled by any PC speaker set, and even very few home theater speakers can defeat the absolute clarity offered by the VideoLogic set. However, the $900 entrance fee is prohibitive to even the most critical and wealthy of audiophiles, which is the exact reason I don't own these wonderful speakers. I enjoy my Klipsch ProMedia 2.1s, and the headphone output is loud and clear. The $150-$180 asking price is very reasonable. Enjoy.
