RE: LCR Phono stage

I haven't tried the a mosfet follower to specifically drive a 600Ω LCR but have heard several variations at the input of an autoformer volume control in an attempt to buffer it. The results were similar to a cathode follower in that the cure was worse than the disease. With a source that has a 3KΩ output Z I preferred the sound without the buffer... moving up to a 7KΩ source it was closer to a coin toss and to me the proper solution is to chose a suitable "low Z" source rather than buffering a high Z one. Maybe there is a magical symmetry out there between one specific Mosfet / 600Ω LCR pair and I haven't explored all the options but I do discount general statements in audio suggesting a generic "perfect" solution to a problem. Ultimately it becomes a balancing act between choices of compromise and the choices made are what leads to a "House Sound"
