Every client has paid The Upgrade Company LLC in full. No kickbacks, no commissions, no fees of any kind for recommending our products and services.
Our "Signature Edition" upgrade we performed to Dr. Stroud's Convergent Audio Technology SL-1 Signature Version vacuum tubed stereo preamplifier
The CAT arrived. The sound is AWESOME! Great job! More later...
