Welcome to AK! I bought my first AVA component, a FET Three circuit kit for a Dynaco PAT-5 preamp, back in 1988 after visiting Frank's shop and hearing his equipment in action. Since then I've bought several more preamp upgrades, a power amp, a DAC, and his famous Longhorn Grado phono cartridge, and I hope to buy another electronics upgrade or two as soon as my upgrade budget is large enough.
