opticon

Hi I currently have a home surround sound setup. This is what I have: Denon 2700h AVR Zensor 3s Zensor 1 Zensor Vokal Alteco C1 I'm looking to buy some floorstanding speakers to replace the Zensor 3s. I listened to some Oberon 5 and 7 yesterday and loved them both. I have no sub so I think...

I am interested in the Dali 5.1 surround system and was wondering if it is alright to mix Oberon 7 with Opticon Vocal ? Are there any issues with Opticon vocal compared to full Oberon setup ? Thanks for help
