I have used a Placette with Merlin's as well. It was a huge improvement over an audio research pre I had previous to it. Incredibly clean sound, very smooth. I now have a Joule but have kept the Placette as I couldn't part with it. the Joule may be a bit more euphonic but not as detailed. I enjoy them both. It's been a while since I had the placette in the system. I guess the real test that says it works in my system, is the I am looking forward to hearing it in the system again with a degree of excitement, it performed that well in certain ways.
