Just an update on the modifications I completed on the 300 and 150. Adding the DC blocking circuit did not bring about additional sound quality improvement. It did however quiet down the transformer in the 300 and the transformer in my integrated amp.
Now if you read back to an earlier post where I replaced the power cable with a nice Furutech on the outgoing female end only, this resulted in a Nice improvement to my ears. The biggest difference is more of a full-bodied sound presentation. All of the details are still there, however they are delivered in a more full bodied and meaty manner. In my system this is a big plus. However, this is both system and user preference dependent.
Looks like @kinghifi said the same thing much earlier on in this thread.
As as for the chassis dampening and removal if the steel bolt, washer, and top plate, not sure how much of the SQ improvement is due to these things.
