l have owned both and they are both very good, owned the Orbe first and it was a tad 'dark' sounding ( good for me)- in fact it was very good sounding indeed and visitors were fascinated with it- heard The AVID at a show ( the original Volvere in Chrome ) and luckily one come at a good price and it was amazing sounding thing for a while, the focus, bass and cleanliness of sound and the sound was forensic, detail was incredible.... however with this warts n all presentation did become tiring for me so flogged The Avid and was Turntableless for a while, in hindsight one thinks that the audio grass is better on the other side and should have kept The Orbe- have a Gyrodec now.
Orbe- dark, full and musical sound-slighty romantic
Volvere- detailed, lean, focus, very quiet surface noise with great bass.
Tone arm was SME V and the cartridge was a Lyra Helikon.
Amps and speakers were the same for both protagonists.
All views expressed were in the context of subjects being plumbed into my system and room.
Good Luck.
