Are you looking for a certain sound, or an accurate representation of the music as recorded? How many professional live performances have you attended in a proper acoustically balanced environment have you attended?
i own a pair of 30.2 XDs connected to a Belles Virtuoso power amp and have can tell you that what is so special about them is that they present the music, not a brand’s house sound. If you like a brand’s house sound you should buy that speaker, because our hearing can be subjective if we don’t know what we really are supposed to be hearing, not what you like hearing.
My 30.2XDs are accurate, and never tiring to listen too. I used to enjoy a pair of top-tier B&Ws and thought they sounded great, until I retired and had the time to sit and actually listen to them for long periods of time- they turned out to be bright and fatiguing. I found similar fatigue when auditioning many other speakers.
Love my Harbeths.
