Sonic Frontier, Joule or Counterpoint Tube Preamp?

I love my counterpoint SA5000. For the price in the used market, it is by far the best value/sound. You get top of line MC/MM phono stage with excellent line stage. Works wonderful with my VDH Black Beauty cartridge, Marantz CD17 player,McIntosh MR-71 tuner and both high/low power amp in two different systems. I used to own a lot more expensive preamps and with a seperate MC step up.
Never had any issue with the unit.
