grateful has a BHK Preamp for sale on the marketplace at a fantastic price. I started by using a Stellar GCD, and went to DSD Sr for preamp big jump in sound quality! Went from DSD Sr. handling preamp duties to BHK preamp with even a bigger jump in sound quality! If you have all the PS gear you listed then you are selling yourself short in my opinion without a bhk preamp!
