I was looking around for speakers that reproduce the music as accurately and naturally as possible. Personally, I don't think this is same as "great-sounding speakers", or speakers that try to sound nice or interesting. In a perfect world, speakers should be neutral and not add any "colouring" to the music.So, my criteria for new speakers were:
- neutral, natural sound
- easy, tight (including ultra-low) bass (no mid-bass peaking please!)
- detailed Stereo image

Arrow is a Dutch speaker manufacturer that has some special principles:
- optimized (flat) phase curve (instead of flat frequency curve). This should ensure a natural, non-distorted sound with lots of stereo information.
- high and contant impedance for easy amplification
- slight suppression of mid-band frequencies to compensate for human oversensitivity of these frequencies.

The Arrow Zeta is a 2-way, closed cabinet system and costs around 2400 guilders (~ $ 1200). They are about 1 meter high and finished in high gloss black, very pretty indeed. I use Van Den Hull CS Hybride cables, they sound alright and look awful (I don't really know much about cables). A 3 year old Denon PMA-680R is my power supply.

Some first impressions (I've only had them for 2 weeks):
- modest, pleasant sound, not agressive or raw
- mid-band suppression not that obvious
- excellent Stereo image with a lot of depth and width
- very transparent, you can easily focus on individual instruments
- bass extends to ultra-low frequencies, "under-belly" bass that is felt rather than heard. Spikes installation improves this.
- No mid-bass peaking (if placed away from walls).
- fast, tight sounding; excellent transient/impulse behaviour

All in all, I'm pretty pleased with them.
