Last year, Onahighernote demo room at the Newport show with Luxman (think they are B-1000F) and Vivid (may be G1) makes me want to take a quick exit. Super Extended Highs is unbearable on the ears. Thankfully, it gets better as the guy changed the source and spins the tape on the tape project RTR. Recalling the experience still sending chills down the spines and hearing is what I value more than the brand or gears. My ears ring for the next two days after the show.
Hope the G3 is tamed at the High Frequency notes.
Good Luck Ivan!
