But, when the midrange driver is being driven by a different amplifier than the woofer, (and in these cases by amplifiers not chosen for the similarity in their sounds, but rather for the difference in their sounds), the blending between the drivers is compromised and the sonic consistency of the speaker is inhibited.It not, suggest you study the close ups of both. Same topology, just different rail volts, and the amount of Class-A bias.
They have the same DNA, by adding more Class-A to one amp is not! going to change the phase integrity from bass to mids. Not that it matters that much anyway, so long as they have the same gain.
I’ve heard magic from Class-D on the bass and tubes on the mids and highs.
He recommends vertical bi-amping with two of the same amps.I do too if they have the "quality in the mids and highs of the Class-A Aegir", but the Vidar doesn’t. That’s why if the Schiits are used the Aegir is better on the mids and highs for it’s sweet class-A sound and the Vidar on the bass for it’s dynamic impact and bass drivability.
