Absolutely the HD6 blows the A5+ out of the water. I started with the A5+, as the HD6 were out of stock at the time. I liked the sound of the A5+ so much I wanted to hear their flagship. I bought them as soon as they were back in stock in April '19. Been listening ever since with zero problems. Paired them with a Klipsch R-100SW sub and SANUS stands and completely fills any room. Much better sound stage, class A/B amp, gapless core toroidal transformers, custom drivers, the HD6 has many improvements over the A5+: larger 5.5 woofers, improved crossover, die cast aluminum baskets for the aramid/kevlar weave woofers, 1" silk dome tweeters, thicker 18mm MDF cabinets, and grill covers, which are not offered in the A5+.
The HD6 is the last set of speakers I'll ever need.
