Hello @tjraubacher , I have literally been there. I had Parasound amps and Classe amps and Preamps. The Parasound stuff is built like a tank, sounds good, and lasts forever. I have had A23+, A51 and A21. But they can be on the warm side and never sounded 'great' until I got an Audionet Pre 1 G3 preamp. I got mine used for about $3500 without the fancy extra power supply. It was my first real experience with better equipment, and started me on a long and fulfilling upgrade path through Audionet amps and preamps. I strongly recommend a call to Bill at GTT Audio. He really helped me.
