I have read loads of forums where plenty of people spend their time offering advice, but you never know what happened in the end
So I owe it to you all to let you know my final decision
I eventually came to the conclusion that the safest option was to get a Rumble 40 V3
And I then found someone who was selling an immaculate example
I've been very pleased. I now see that the Rumble 200 v3 is a seriously deep beast bearing in mind its price point, so a smaller piece of equipment is never going to quite measure up
But my wife came home recently while I was playing and she commented how loud the 40 sounded from outside our house
And I've read the guidance from AstroSonic about how you can upgrade the speaker and sound if you want to, so there is an upgrade path, and that's great
So thanks once again to all who contributed
