Most enjoyable speaker you heard under $800??

Pioneer BS 22. Not attention-grabbing, just musical and very easy to like...at under $100.

Silverline Minuet Supreme Plus

A pair of Wharfedale Denton 80th Anniversary bookshelf speakers, gorgeous retro craftsmanship, most probably will enough for you enjoy all musical genre, and listen the bass is surprisingly deep and tight!

For me, it's Magnepan's MMG in a walk.

ZD542 - I am not great with audiophile descriptions, but the results of the A5+ with my SACD player made me believe that I could be happy with the combo if something happened to my Focal 836v speakers. Using the Airport Express the sound is more like an old tape player lacking detail, clarity, and dynamics in comparison. It just sounds ok rather than surprisingly great.
