Hi James, you said the tag line should define what Bryston is or does, but another approach might be to define what state your client is in after acquiring your product.
I purchased my first Bryston product ~40 years ago. Something like "designed to outperform, built to outlast" is very well fitting for you guys, but lets look at the impact you have on your customers.
After buying Bryston, your customer...
- no longer worries about reliability
- no longer worries about achieving better performance
- no longer worries about support
I think that speaking to the outcome, or state of audiophilia contentment achieved is more powerful. Words like pursuit, anticipate, expect, sound like you are still trying to get 'there'. When you in fact you have already been 'there' for a very long time.
For me anyway, Bryston means "Performance and reliability, achieved". the only thing left for me to do is "Let the music play".
