I own D7’s and love them. Not bright at all, upgraded tweeter vs A7. I first heard D7 immediately after listening to A7 for 40 minutes- difference in quality was MASSIVE. I knew right then my budget for speakers needed to jump above my initial $5k target.
I’ve posted a lot about them across various threads (you can quickly scan - I think I still have less than 100 posts).
Basically I thoroughly auditioned a couple dozen speakers between $3k and $10k over several months and liked D7’s best.
But that’s just my preference.
Gotta go listen to as many as you can would be my recommendation, but yeah Spendor D7 one of most acclaimed speakers last 5 years - just seek out the reviews. It’s difficult to find anyone with anything bad to say about them.
Oh and if you generally like tonality of Spendor but want a little more reserved, then I’d suggest Vandersteen may be well worth auditioning.
