I'm going to be (respectfully) blunt, because we seem to be talking in circles and I'm not getting the assurance I'd like.
Setting the issue of budget aside, because I'll grind what grist the mill requires in pursuit of SQ, I would like to understand how much of an improvement Hypsos creates. It's £1000, so what am I getting for that? Is it night and day? Horrible cliché, forgive me. Or is it subtle? Could one live without it and be happy? Or is it a must buy? If it's <5% improvement then I wouldn't bother. But if it's more impactful than that, then it's something worth considering.
