Would be from a humble manufacturer. These are pristine looking floor standers with excellent finish. And a sensitivity of 90db, to go with the atoms low power. And they are the qacoustics concept 40's. I had bought the PMC twenty 26's , with the intention of disposing the concept 40's. But haven't been able to get myself to that. Such good speakers they are.
Most models you have mentioned are step down models of great brands. Where they are just trying to give the customer a slice of their sound at a price they deem acceptable, to egg folks up the ladder. But the concept 40's were qacoustics's best effort ever, till the concept 500's came out a little while back. And it shows in the concept 40's performance. They run so close to my PMC's. The PMC's have better bass. But the concepts have better vocals. Considering the price difference between the two , I would give the concept 40's a solid recommendation.
The concept 40's are slightly laid back on very fast charged tracks. And the Naim's are relentless in their pace even on mellow tracks. So both cancel out each other and make a perfect pairing.
Sadly you can't hear the combine. So I presume you would deem it safe to go with the big names. But I thought I'd give you a heads-up about a great pair of speakers. All the best 🙂
