The team at Burson was exceptionally helpful and responsive. They promptly answered all my emails and made my decision-making process much smoother. Additionally, I received a complimentary set of V7 Vivid opamps for my Soloist, which was a pleasant surprise. I then decided to purchase a set of V7 Classic opamps to try out. Despite the challenge of coordinating this from Lima, Peru, in South America, their support made the experience very positive.
