Sounds to me like you are very happy with what you have and are just wondering if there is any way to make it better. You could try Pass if the itch is unbearable. My Aleph 30 is ultra detailed and very musical. Dick Olsher (toob man) once wrote that it was the first SS amp he had ever heard that would allow him to forego tubes.
Personally, I'd leave well enough alone. Why tamper with success?
