The AP Crystal Solos continue to reveal whatever is thrown at them.
This week I changed out vintage Sylvania 6SN7GT preamp tubes for new-production Tung-Sol tubes. A lot more burn-in required I gather. Nice and full sounding right off the bat. Clean but a bit dry and less texture in the first 10-20 hours. The AP Crystal Sol ICs do what they are suppose to do for sure. Hoping 80 more hours of burn-in will help. It’s worth a test I guess...maybe TJ Full Music next.
