Thank you to all who have responded. You have provided a wealth of good advice about audio tweaks. I often wondered how important speaker connectors are. Fortunately, the connectors of the several speaker cables I have owned, seemed more than adequate, but.....
The Harmonic Technology Pro11+ I purchased used on AG came with expandable banana plugs. Most work, but some seem difficult to use. easily However, with garden hose thick speaker cable and these types of banana plugs, there is always the risk of breaking the speaker connector, especially if the speaker connectors are made of plastic and because the torgue of the cable because of its thickness. It is worse if the cables are longer than you need, which is a problem I have with the HT cable. It is a 12 ft pair. But the sound they provide is excellent The speakers are the Golden Ear Technology 7's, a very good speaker, but the speaker connectors are cheaply made.
The speakers came with a ceramic oval base with standard spikes. Occasionally, there is a bit of overhang in the low bass which could be related to several factors. I have considered using a one inch "dense" wood platform of equal size to further decouple the speaker from the floor which is carpeted. A couple of months ago, I called up The Cable Company, and they advised against added elevation of the speaker to insure the correct ear to eye line from the tweeter to the listener's position. I am very familiar with this standard rule of thumb caveat, and saw nothing in the manual advising against a minimal elevation; unfortunately, I have never felt confident with The CC's recommendations or advice. At times, they can be unfriendly and dismissive
BTW, do "Audio Additives" RCA caps for unused sources reduced the noise floor as claimed. Music Direct sells them, and they are reasonably priced. Thanks, SJ
