HD/IBOC noise performance of Marantz 125 and 150?

My understanding is that these two tuners are similar except that the 150 has a scope where the 125 has meters.

Many tuners are noisy in stereo when the station is also broadcasting HD radio.

I read that the later Marantz 2130 has a post-detection filter which should help.

Does anyone have experience with the performance of these two on that issue? If so, I ask that you please share your results. Thank you!
