I have been playing around with the ICOM R75 for a few days, and yes, I found it excellent high quality receiver way over the level of the S2000.
The twin PBT work treat. When copying the weak signal from VoA txed from Botswana 6080, the signal was barely audible with no intelligibility initially. When tuned and peaked with the R75's twin PBT, the signal came up stronger and became readable.

And the 2x preamps, W and N filters and S-AM mode all work great and are very useful . The audio is clean and crisp. Overall  4.9/5 from me.

It is either a MLA30+ or Long Wire with Ameco PT-2 preamp.  The latter seems work better for DXing.

My R75 has been collecting dust. I fired it up after seeing this post. It is a very good receiver.  Especially for SSB, it needs a TCXO. I need HI FI broadcast audio so I will build a SDR 9 MHz IF board then feed it to a 192Khz sound card with HDSDR with CAT control to sync frequency with the R75. This would make a great setup.

Interesting.  Let us know how you got on with the set up.

Just wondering, if your R75 has the DSP installed.  Unfortunately mine doesn't have the DSP, and I wonder if lack of DSP in the set makes the narrow filter sounds muffled.
Yes, my only problem with the R75 is that, when the narrow filter is selected, the audio becomes awfully muffled.  Due to this, I have been using it with the Wide filter selected only, but many times, I find it too wide, which gives selectivity problems.

Compared to AOR 7030, I prefer R75 AM audio.

The R-75 has 3 stock filters 15k 6K 2.4K. If properly set up in the filter selection menu (see operation manual) you should be able to access all of them. You likely have it set up wrong. If a filter is selected to off (in the menu) it will sound muffled. The 2.4K filter is to narrow on AM but is still useful on very weak stations. If you off tune the AM station you should hear a difference between the 15K and 6K filters when switching them. I found that my R75 was not set up correctly. Now I have all 3 filters working as W-15K, 6K, N-2.4K. Also if you can get a used or old new stock DSP it works very well.

Great info & advice MRI.  Yes, that sounds right. I have not read the manual yet, as I just got the R75 a few days ago. Just powered on temporary set up for checking out, that it is working OK.  Will need to set it up correctly in the new room - as my daughter moves out this weekend to her new flat in the city, I shall have her room as my new SWL/BCL room. :D

But yes, after a few nights of listening to the R75, I feel that it is an awesome radio.  Even with no proper set up and temporary trying RX, it sounded like the most sensitive receiver I have ever come across. I will get the manual out and read up for setting the filters.   I am looking forward to this winter season for some interesting DXing with the R75.

I have set up the filters on the ICOM IC-R75, and now it sounds beautiful.
A great receiver, R75 is.
