Sorry I had not been able to update this thread. I am using the same setup almost daily.
For some music it sounds amazing; for others, I just dont feel the connection with the music. At this point, I am thinking of buying another amp altogether. I can sell the Krell later, if necessary.
Because of previous (very positive) experience with Naim (old XS) I am leaning towards the new Naim XS2, or the Supernait 2, or even the Rega Elicit R. I will audition these next week. Some have suggested valve amps in this thread, I will see what is available in the market (in Singapore) and see if I can audition those. Will update the thread accordingly. Any more suggestions and ideas are most welcomed.
Have a great day.
