I recently purchased the Anthem AVM-90, and I'm delighted with its performance, particularly in handling subs and its phase-matching capability. The AVM-90's ability to eliminate guesswork and seamlessly blend all four of my subs with my mains (B&W 804-D3's) is a standout feature. This alone, coupled with the excellent sound quality, makes the AVM-90 a worthwhile investment. Finally, I've achieved the desired audio experience from a pre-pro without the need for a $15,000 budget.
While the Lyndorf and Trinnov may offer superior features, it seems that the AVM-90 provides comparable performance at a significantly lower cost. In my tuning experience, the difference doesn't justify double or even a $3,000 higher price tag. I'm thoroughly satisfied with the AVM-90, especially considering its sound quality, higher end components and DACs and expanded features compared to the 70.
