You should check out PS audio web site, they have several that work well. I would plug amp into the wall.

Here's an idea,
1) figure out how much electricity the 590ax draws. You can do this by picking up a Kill-A-Watt EZ at H-Depot for $30.
2) Pick up an Ultra Isolation Transformer on eBay that is about twice the wattage or VA that you will need. Cost depends on the size you need, and usually from $100-$500.00
3)Go to your breaker box and find the breaker that is used for your system. Have the transformer wired directly to the breaker on the transformer input side and wire the output side with the Romex that leads to your system.
Your system will be protected from spikes and surges as well as isolated from all of the other noise on the line.
Check building codes before doing this!!!
I own top of the line Shunyata conditioning gear and promise you that the best defense against surges and spikes is a whole house surge protector installed at the breaker box. ($250 installed)
Your Luxman will do best either plugged directly into the wall or into a non current limiting conditioner, but IMHO there isn't one of sufficient quality in your price range. You could try a $195 Shunyata defender at the duplex where your amp is plugged in. I believe music direct offers a free trial and the device does not limit current.
If you are going to go with a whole house surge protector, I strongly suggest you look into the Environmental Potentials EP 2050. It will run you a little more than your budget, but it is more than a simple surge protector. It will also send the noise from all of the houses that are on the same transformer back down the neutral and isolate your house from them. I use one and like what it does. Do a search to get more info on this great product.
