I own a Krell 300il for about 3 months and it runs very well with my Wadia. I also own a tube amp CJ MV-55 which I connect it directly to Wadia. To my ear, the Krell 300iL sounds great and like tube. I would rate CJ is slightly better for female vocal sound (4.5 vs 5.0). But in some CD, Krell 300iL is the winner. I do not notice any bright sound from this Krell at all.
