Bullet bitten and trigger pulled

[E-Stat]

The ARC LS9 seems to work pretty well with the X150.5, though a few recordings are a bit bright. This is unlike the Class D Audio amp that made the majority of recordings more or less bright.

Exactly. Some, but not all recordings are innately bright.

The LS9 stays on all the time; so does my Schiit Audio DAC. The X150.5 I turn off overnight or if won't be listening for a couple of hours since it sucks 200 watts at idle.

I have modest PS Audio shielded PCs on both the ARC and the Pass Labs.

Good on all points.

The Magneplanar MG 1.6's are amazing speakers: they are able to exploit any improvement you through at them. I'll be keeping them for quite a while.

I think I mentioned a while back I heard 3.7s driven by about $90k of sources/amplification/cabling at Sea Cliff. They can be as good as what you feed them.
