I am running my system via two preamps, the ARC Anniversary Reference 40 and the EMT JPA 66. Both preamps can be switched by a special device both XLR connections putting on active/non active position.

Both preamps got new tubes, the EMT NOS ones. While the EMT runs turntables (currently via XLR) the ARC is responsible for the CAELES II/ Allnic 8000, the tapes and the digital line.
