That's not my job. I'm at the behest of the host. He's happy to run his system as he did. I'm not familiar with the gear, or how his room sounds w alternative gear.
But in a system w all ACerat dac/amps/horns, a server that was up there w the well regarded CDP that we also listened to, and a renowned loom of cables, what am I meant to object to/suggest?
My only suggestion is that the room was a challenge, but it's a typical room you'd get in a £1m+ N. London house, and had some treatments.
On the basis of all that, I drew my conclusions. Just like people do of my system when they visit.
As I say, it was engaging on a few levels, but a certain mids harshness intervened.
