I went to RMAF a few years back and brought my wife. She has a healthy amount of skepticism and calls it the way it is. She heads into a room with some vinyl she just purchased in the marketplace and the host throws it on. There was about 500k worth of equipment playing her disc and I knew we just approached the crossroads with the needle drop. It was unlistenable and after two tracks the album was politely returned to her. I found myself making excuses for a half million dollars worth of equipment. The room was crap, the vinyl was poorly recorded, high end systems reveal more of the truth, crap in crap out etc. Her take was she loved the artist and wanted to enjoy the record….. was tired of three days of well recorded jazz.
Yup a 40k amp should sound better than a 10k amp but often doesn’t. If I bought it I would have auditioned it in my room to see if it met our very subjective definition of better. If I bought it without auditioning there is a good chance I would be cornered into making excuses. Been there done that.
