What's my next step in AC conditioning??

I'd start with a good outlet. Search on some comments by LAK. He seems to have done the most research, via his ears, on this topic.

I've tried Hubbels from Home depot, PS Audio Power ports, and Porter Ports from AlbertPorter here on audiogon.

For under $40...the porterports are a steal, IMO, and in my system. Better dynamics, more queit background.

Your amp might be best plugged in outside of the conidtioner. The front end components only into the conditioner. After expiramenting...I sold my conditioner for everything...but YMMV.

Umn:
What do you have plugged in the HTS? What components?
Do you have a dedicated line?
There have been several threads on this topic that you can benefit from...
The HTS which I currently use, is a nice piece but there are better options I'm sure you'll get input from other members about this.
Would like to suggest some trials to you but need more system details
Regards

Into the HTS I have:

CJ MV-55
Creek OBH-12 passive preamp
HAD 512 CDP used as transport
MSB Link II
Scott 350 FM tuner (vintage)
Sony Cassette deck (I am always dubbing for my kids)

It is not a dedicated line.

Thanks.

Oops. Typo. That was a NAD (not HAD) 512!
Sorry
