The 450 was definitely underpowered at just 226w by anyone else’s measurements.
The hard core, baked in, compression to artificially boost the troughs felt like it was pumping top & bottom end but sucking all those lovely mids.
With hindsight I guess I was fooled by that compression and could have partially got around it by boosting mids but the fact that it was permanently engaged just took all the transparency and organic tone away for me.
