First best preamp is the Wavac PRT-1 but that is ,000. So close alternative is this one - a PRX-2 Mint as new Wavac Pre - very little hours, boxed and beautiful - currently new around £8,500 - selling as changed system from Wavac. Never seen one for sale EVER before untill this week - one in Germany second-hand asking 5,500 euros. Mine best offer close to £4000. :)
