I agree with the electronics as the starting point to address LF. Two months ago, I replaced my modified Music Hall CD25 cdp with an EAD CD1000 series III cdp. I changed nothing else to include my listening environment. The sound was much easier on the ears. In my system, the CD25 sounded very detailed, almost too detailed. The CD1000 is much, much smoother sounding, with a warmer feel.
Just my opinion from a very recent experience.
