Gustard H10 with Burson V6 Vivid Opamp
Generally clear progression of auditory sensations with respect to V5. In spite of GAIN +6 or +12 settings, in my current configuration, significant overheating of opamps (especially double). I’m thinking of modifying the amplifier to improve cooling

The opamps are really plug & play. Very easy to install and a joy to listen after burn-in. Highly recommended!
