Axpona audio show. Is it worth seeing(hearing)?

If you are in the market for any particular components, visit the vendor that has the component you want to hear, plus visit vendors who have competing products in your price range. You may find some surprises.

If you want to learn about vinyl playback, or computer/streaming audio, visit vendors with those products. There are also vinyl seminars, as well as computer/streaming audio seminars.

Lastly, go see a vendor/product that is WAY out of your budget, just to see what is possible and what all the fuss is about.

droleg,

If you are a hi-fi enthusiast, and if it's nearby, I suggest you go and experience an audio show first-hand. Unless you are in the industry, or in a major metro area with lots of hi-end shops, you'll likely never have so much access to so much different equipment. 

If you go, have a plan. Check out the vendors you want to visit and make sure you get to them. Otherwise, you could get overwhelmed and miss the very things you went there to see/hear. Also, plan you schedule around any of the seminars you want to attend. 

Go to the show website for a list of vendors and products, as well as a show schedule.
