In my opinion the XO version is the best of the A3 variants, able to communicate not only the detail in a recording with a natural tone but also the emotion of music. For sale my Gold Note A3-XO bookshelf speakers.
Small bookshelf speakers with a BIG sound. Given the size and considering that these are not high-end speakers, after filters were modded, the sound is amazing. The speakers are in good condition with a few marks here and there.
