I had the Benchmark LA4. It was very neutral with very precise volume control in 0.5 db clicks. I had the complete Benchmark stack at the time so I am not sure how it would be with other equipment. The DAC 3 was sending the full 12 Vrms analog signal to the LA4 so system synergy was in play.
But I too could not look past its awkward half pint looks, and other than on a tablet, I was not a fan of touchscreens on my hifi equipment. Sold it.
