Let me share my experience with Focal 1028BEs and amp search. I auditioned these speakers with may be a dozen of different amps and I cross out A21 almost immediately. The sound was dull to my ears. Not good highs. No spark. Not much details. I'm not sure that you can fix the problem removing only A21 from your system. Maybe preamp have to go to. May be. Macs looks like the easiest next step. After few experiments I stay with Mac C22 tube preamp and Burmester solid state amp. I like the sound very much, but, as you know, there is always smth better. I wish I could try new (cubed) Bryston in my system. Or Mark Levinson! But you know, it's not an urgency I'm just lazily interested.
I also use OPPO 105 player, Linn LP12 with Goldring MM cartridge. Analysis Plus Big Silver Oval SC & Kimber Silver Streak IC.
