Best monitor for bookcase ?

Sonus Faber Toy Speaker (monitors) - they deserve to be on the audition list. They are small, inexpensive, and beautiful sounding. I am listening to a pair right now and they do a great job of pulling me away from typing to listening. They are in a small room (about 8.5' x 10.5') which helps. The speakers are rear ported and proximity to the rear wall helps in their case.

They are driven by a 30wpc tube amp, fyi.

If the book case is fairly deep, I'd recommend the Daber Audio Monitor 2's.

The word AMAZING comes to mind. I had been warming them up for a couple of days, just pushing low volume current through them 24/7,getting them a little broken in and getting my new Rega stuff all good and warm (Rega Brio R and Rega Apollo R)

First cut: Adele's "Rolling in the the Deep". Soundstage was first thing i noticed, how the background vox were layered behind her lead Incredible!!!

Then the bass presence: obviously not thunderous but on that particular cut the depth and resonance is there while still being ultra-tight; palpable and fantastic. Hard to believe that kind of bass can come out of a monitor so small!

I've now changed to a small EL34 tube amp and they are even better. Amazing little speaker, and I see myself having them for life.

I believe this speaker is a world beater. They're obviously not for rockers, but they are precise, realistic beyond words, and incredibly articulate. I know of no speaker under $1k that can touch the Monitor 2, and very few under $2k. WOW WOW WOW!!!!"

Isn't it ironic that one of the last places you'd want to put a "bookshelf" speaker is on a bookshelf?
