I replaced my 38S two years ago with the 380S. I still have the 380S today and it has been a wonderful upgrade. The 38S, while having a very low noise floor, has a very antiseptic sound, e.g. clean, detailed, but no body/emotion. This was the biggest change for me when going to the 380S. I have been looking at the 320S as a possible upgrade option when it becomes available. I think you will find that it will be cheaper for you to sell your 38S and pick up a used 380S vice sending yours into Harmon, provided they are even going to still offer the upgrade. My experience with them is that they do not support upgrading a model to a newer version that has also been discontinued. Enjoy.
