I would certainly recommend my pre-amps, except for one detail: I have only ever seen 4 for sale, ever, and I bought two and sold one of those. The other one was on a Canadian site. So it does not matter. Good Luck. I recommend you listen and buy what you like to hear. You are on a site with extremely prejudiced listeners, who often taut what they own to make themselves fell better. Many are going deaf from age. Visit a city with dealers. They still exist. To save money, if necessary, buy used, but listen first, somewhere.
