hi Jafant, good to hear from you. yeah, lots of changes truthfully.
1. added another REL sub
2. got the PS BHK mono blocks
3. got their new transport
4. replaced the P10 power plant with a P20
5. replaced the PS preamp with a Pass preamp, the XP22.
so the only pieces that are still the same, gear wise, are the DAC and the speakers.
