I have O&B SS2150 class AB amp currently and It is powerful amp.
I recently updated my DAC to Musician Pegasus R2R and liked the direct sound out of it so sold my tube preamp which was filtering high frequency micro details coming out of DAC.
My current setup:
MacBook pro > Pegasus R2R > O&B power amp with volume pot > Dali blue 6006 floorstanding with SVS SB 1000 pro sub
To be honest, I am not sure what is lacking in the system, but I feel I can get more sonic improvements.
I feel I am not getting depth or imaging in my current setup so thinking if I can get it by updating to different class Amps like A or D, but not sure which path to take so thought to get audition from existing users as I never listened to class A or D amps.
I read that latest class D amps like Sabaj ICEpower modules had made significant improvements and has good imaging and depth and they do sound good so would try to listen them as well if someone already using them in Pune.
