If by “Japanese” you mean “hifi”, I’m feeling that generally. It seems to require adjustment of the system to adapt to the changes. Ted has mentioned a change in the phase of the bass, so it may involve adjusting the phase and/or position of your subs if you have them, or moving your speakers. Most feel it is brighter, and a fix for that is toeing your speakers out some, which with most speakers results in you hearing the tweeters less on-axis, resulting in less treble. As long as it doesn’t kill the solidity of the center image, you also get a bigger soundstage.
Huron has a lot of positive qualities, but going in, I didn’t feel like Torreys was deficient. So, jury’s still out for me. I like to do long-term listening of stuff, so I’m going to give it a while before I start with the MQA-type raves ; ). (…and I say again - ; ). I’ll be perfectly happy to be proven slow on the uptake.
If I recall correctly from the DSSr. Thread, it’s possible that the sound may change with a reboot after install, if you haven’t already done that.
