Finally decided between sr80 and sr225 and got my sr225. However I use (atm) portable source and the guy at the shop gave me a 1/4'' to 1/8'' that doesn't work good with it. The left and right channel don't sound as soon as you twist a bit the cable.
After 10 minutes usage putting the plug is useless. It falls (doesn't have enough strength to hold the big 1/4'') So i won't be able to use them during this weekend...
