All good responses here. My 2 cents worth. If you are happy with the sound quality of the system, just stick with what you have. There will always be something out there which will sound different and/or better than the current gear that you have in your system, whether it’s the amp, DAC or any other component.
Attempt to upgrade or change the amp only if there’s something bothering you ie. some aspects of the sound that you wish to address. If you have unlimited funds and/or are bored and want to have some fun, you can always choose to tinker with the system by swapping amps on the 30.1.
I’m rather familiar with Harbeth speakers and have listened to the M30.1 but do not own it. They respond well to amp, source and cable change. The 30.1s are rather inefficient and require a powerful amp to provide the current and drive.
