Conrad Johnson CT5 , 16LS or Herron Audio VTSP- 3A (r03)?

I have been a fan of CJ for a long time. But I’ve had their SS amps and PFR preamp. PFR sounds great. Whole system does. However I apparently am not going to be satisfied until I replace something. I’ve been wanting a tube pre for a long time. The 16LS was a dream many years ago. I know the newer CJ has a somewhat different sound but still gets good reviews . So does the Herron which I am not familiar with except in what I have read. I had beejn going after the 6SN7 tube circuit, (IE Sachs, deHavilland) But I know other mfgs which make top tier preamps use other tubes to great success also. So, which is your choice? It will be paired with a Latino ST-70 fully modded....at least for now. Thanks
