Pubul57, I would not say that my TVC is warmer than the LA-150 MkI, just that it is a tad warmer than most passive preamps. If you like the Placette as much as you indicate, I don't think the LA-150 MkI is going to cut it for you. Yes it is neutral, it is revealing, but I think it will not match the transparency and frequency balance your Placette gives you. It will come close, but you may regret the buying decision and unlike other gear, for reasons unknown to me, the Joule units don't have very good resale value.
Sometimes the best solution is right under your nose.
