My advice is that you buy a second-hand Stax amplifier and you use it until the BHSE arrives. Then you can sell the Stax amp almost at the price you paid for it. My upgrade path was: Lambda 404 and Stax 007tII (which I bought from different owners), then I bough a SR007A, then BSHE, then SR009, then I sold the Stax 007tII. They were all second hand except the BHSE.
