What I can hear so far is that Trifield is delivering an impressive width, staggering and massive improvement stereo build up.
If you have another (preferably digital) source, you could run that straight into the 568 to hear what it can do on its own with Trifield.
In my experience, Trifield comes into its own when you have rear ‘speakers, with some music it can really envelop you into the sound.
For it to really work well, all 5 ‘speakers need to be the same or similarly voiced and phased.
All the best,
Steve.
