need help choosing line condtioner

If you have a budget and want better sound, do dedicated outlets-you will get far better results doing this then any conditioner. The only one that I care for is the Shunyata Hydra (which is a little over budget) and it can have a very negative effect on the PRaT of your system-so in home demo is a required. But if I were you I would do dedicated outlets first, and then think about a conditioner.

Dedicated lines for a college student in a rental situation is not a likely prospect. Go with a Chang 9900 Amp (30 amps capacity) for the PA's & then a smaller lower-curent source component unit for the rest; perhaps the Chang 6400 Iso.

Consider Virtual Dynamics power cords. The power conditioner is built in. They also have a 30 day return policy if you don't like them.

Good Listening,

I live in an apartment and use a 3000W ONEAC isolation transformer. I also have a Tice A/V Solo, but it's not a good idea to plug my amp to it.

You can get a *big* isolation transformer in eBay, but it is going to be 220V in for what you want it...

Sedond is using two VE unlimiters and is happy with them. I would try good power cords (whatever design, no debates here...) and also try a Highwire Wirewrap. For $25 it's worth a try--I have one to help my power amp and it smoothens sound by removing RF grunge.

Going to parallel filtration is also a good idea--as well as getting some surplus isolation transformers for your digital gear.

The Blue Circle BC85.1 is a great line conditioner. The unit retails for around $800. See if you can pick one up used. You won't be disapointed.
