As it stands my system is fast, detailed and transparent. I would like to add a touch of air and harmonics to the system and perhaps enhance the focus a bit. I also want to enhance my system dynamics, hopefully by adding a high-current power amp. I have a Supratek Cortese Linestage on order. I am also going to replace the 4B-ST. Probably with a Sim Audio Moon W-5. I don't have problems with the sound of the Bryston but it runs out of steam sooner than I prefer and I think an amp that doubles down into 2 ohms will enhance the dynamics and control of my Thiels. I would appreciate comments on my proposed amp selection. The other alternative amp that I am considering is a Pass Labs X-250. After upgrading my preamp and amp I will add a single disc transport. Probably either a Vecteur D-2 or Rega Planet.
