@asmithkash Congrats, on the KRELL. I am assuming it is the K-300i. I have not read all of this thread, but I saw somewhere that you had a bad room.
Here is something to consider. The reason I bought the KRELL K-300i was to be a headphone amp for the RAAL SR1a earphones. Pair the KRELL with the potentially bright RAAL SR1a and you have some of the best "2-channel like" sound in your room. The room acoustics do not matter with the SR1a, unlike the B&W.
The K-300i can easily be setup for both SR1a and B&W at the same time (a flip of the switch on RAAL the adapter box). Something to consider if you like to listen late at night when the family is sleeping, like mine. Only problem is I stay up too late and do not get enough sleep.
I am bummed out that I sold the K-300i because I could use it again in my bedroom as a headphone amp (I needed the audio $$ when I sold it).
