Thanks for your advice, the system will be in a room about 4 square metres . It's good to know that I won't be doing anything thing fundamentally wrong by choosing the 606.
Definitely not aimed at you. I am most grateful for your comments and would not want to give offence in any way. I'm new to this forum thing and am still finding my way around it. Kind regards to you.
I would prefer to have speakers. The room that the system is going in is above 4metres square. The floor is Amtico and has curtains making it an acoustically bright room. All this is because it is to be a dedicated music room with a Steinway grand piano in situ (when the lockdown is over)!
