Very good recording quality. Audium are superb speakers. I have the Audium Comp 7 Passives driven by the Lab12 Integre4 integrated with kt150 tubes in the output. Very happy, great focus, dynamics and staging, and they bring forth the analogue flavour of the Lab12 Dac1 SE very clearly streaming Qobuz. Can you tell me what the 'discs' supporting the spikes are, and how they affect the sound? My Audium's spikes are on 25mm granite on carpet and the front of the speaker tilted up as recommended.
