Best speakers for hi-def music in home office

Forgot to mention I want the speakers to sit on my wooden desk.

You could go with a pair of KEF LS50 wireless speakers which would replace you main speakers, amp and pre-amp. They have DSP which allows you to configure them for desktop placement, near/far from walls, etc. According to the reviews I've read, the DSP is very effective for setting up various different placement options.

I replaced my small office setup with Vanatoo Transparent Zero.  Small enough to easily sit on the desk. Highly recommended.  They also have the slightly larger Transparent One Encore.

Buy them all pre-owned:

Atc SCM 11 

You can get amazing sound with the Naim Atom, see the thread about a guy who replaced a big really expensive system with the Atom.

Then there is the Micromega M100 which is fantastic, a bit more expensive but more power with a room control option.

The ATC SCM 19 are amazing compact monitors they image like crazy and are sealed cabinets, they go low enough to be impressive but not too low to overload a room.

Please PM us if we can be of assistance we sell a large number of great all in ones, Hegel, Naim, Micromega, NAD, as well as lot of great monitors at all different price ranges: Quad, ATC, Paradigm, Kef, Cabasse, and a few others.

Does the REL have an internal amp?
Regardless, There is a Rogue Audio Sphinx v2 integrated on Audiogon now for $950. These units have " Tube driven active outputs for subwoofer" . Add a modestly priced DAC (like a piece of Schiit) and you still got 8 or $900 for Speaker choice.   Then after time you gots the flexibility tube roll and upgrade the DAC as DSP technology progresses.

Here is a review on the Rogue

Shopping for someone else is fun:
Check this out: Tidy foot print, Built in DAC, USB input, pre out to run the REL. >$1k for Speakers. Although I like the Rogue/Schiit combo better.
