Do yourself a favour and check out the Spectron class D amps before you change the speakers.The virgos or nautilus are both excellent but you may well be surprised at how good your old speakers sound with a Spectron driving them.Frank.
Nautilus or Virgos?
I'm currently in the process of upgrading my system which presently consists of Theta Miles CD, BAT VK-30 preamp, SimAudio Moon W3 amp, Hales Revelation 2 speakers, and REL Strata III sub. The speakers will be the first to go as I've had them the longest and I am currently considering either the Audio Physic Virgos or the B&W Nautilus 804s (or 803s). The next item to be upgraded would probably be the amp, to a Plinius SA100MkIII. I'm wondering whether the Virgos or the Nautilus would be a better match with the Plinius? Although I listen to a lot of jazz and vocal, I also listen to rock and techno/electronica so I'm looking for something which would give me a very natural and lifelike midrange (which the Hales have) coupled with speed and attack. Also, since I live in an apartment, I'm looking for something which would sound good at lower volumes as well. Your views on the Nautilus and the Virgos would be appreciated. My budget is about $3000 to $5000 so any suggestions would be welcome too.
