Post Subject: My preamps revision: New Placette gain buffers.Posted by Romy the Cat on: 6/10/2018
After 13 year of using of my active Placette my preamp now is undergoing a modification. My knew listening room is rather on larger side (acoustically) and I am driving the whole system from super Milq, no help of SS amplification at the lower knee. So, I sometime feel a need to have a few more DBs of gain, particular running video over my main playback or listening CD recordings with low dynamic compression. The subjects of having enough power is a bit more complicated and I would like to live it aside of the conversation for now as I am care about the gain at this point. The Placette at full unity gain is not enough for me as time and I was wondering about the solutions. The aftermarket line-level gain stages are horrible, not that I tried all of them but a few that I did were a joke.
 
I learned that Guy Hammel has a new active buffer that can provide 6dB and 12dB gain. We were discussed it a bit and I decided to try it. I still do not want to lose the original Placette active buffers as I feel that are a benchmark of transparency. So, I asked Mr. Hammel to install in my Placette parallel to the existing original Placette active buffers then new gain buffers and to make my Placette be able to be switched running original active buffers or new gain buffers. The new gain buffers have the same ultra-low output impedance that is mandatory for me to drive my Milq’s filters. So, I am very interested to hear the new Placette gain buffers.
