I am delighted that you found and enjoyed these SD45 recordings. That V20 does have its distinctive low rumble. It is a real thrill to get them into run 8 and then walk outside and listen to them roar away. Can't do that when running, of course, but I can open the door; for air flow naturally!
My recorder is a Sony ICD-SX57 solid state tiny little thing, but it amazes me with the quality of the recordings of which it is capable. Amateur to be sure but still quite good. I post train recordings on ebaumsworld, mostly because it is free and they do a good job. I have some additional recordings which I plan to post.

There are also some good recordings of the GP7 with its original 16-567-B roots blown engine. My personal favorite is the middle of the night recording of the BNSF SD40-2's.
I post videos on youtube under the handle "np560". Unfortunately a youtube search on "np560" also gives unrelated posts by np-560, but you will see my posts there.
