I am replacing my Adcom line conditioners For no particular reason other then their being nearly 20 years old. I already bought a sx1115rt for one system and like it. My plan is to get a 7500 in the fall or winter (heavy stereo season) for my main system would the Surgex SX1120RT handle the power needs of the 7500's draw with my other gear including the DD15 sub, if not what would, or should it go directly to the wall. I want to protect my current gear( little punny there) but also have what I need to move forward.

I power my 7500 and 990 and Aperion sub from one APC h15 power conditioner/surge protection and it does just fine. Remember that although the 7500 could draw 1500 watts all by itself, it is almost never called upon to do that and even then it would only be transient. Same thing for the sub for the most part.

I have a free performance upgrade advice for you. Plug it straight into the wall like I have my 7500 and my SVS pb13 Ultra. This advice was given to me from a proprietor of two high end audio shops who sells MacIntosh, Boulder, Rel, Vienna Acoustics and more. Do not limit dynamics on a high powered amp with surge protectors and power bars. The only item that you can plug the 7500 into with sound improvement and no dynamic power compression is a Shunyata Research Cyclops. That will cost 2K.

Sounds fine until you take a lightning hit close to your house. The protection afforded by the APC has Proven itself multiple times over the last 5 years. It is likely that the audio store has built in protection so they don't need extra protection.

There are LOTS of dumb/crazy/deceptive "high end audio propietors" out there.

Get a quality line conditioner! I absolutely can GUARANTEE that it will improve the sound of your audio system, improve the image of the your video displays /sources AND all but eliminate any chance of damage due to either lightening or power company issues.

Start with one of these:

I wouldn't recommend a line conditioning power supply for improvement in any aspect of my systems. However, I did get almost 10000 hours of use from a DLP TV bulb. Although it is nice to have some voltage regulation, the primary reason I would recommend the protection afforded by many of these devices, is against lightning and voltage transients.

Maybe if you live in an area with very modern all underground power company lines(which are unlikely to pick up RF), a utility that never does anything but top notch maintenance / service, and a home where all the "high draw" appliances are well isolated from the A/V system the improvements when switching to a nice well regulated power line conditioner will be less noticeable than in an area with above ground lines, poorly maintained utility feeds and typical appliances but I swear you will still see / hear the difference. Believe I am as skeptical as anyone about any sort of "audio snake oil" but the reality is that MOST homes do have some real problems with their electricity and well designed conditioners clean that up. The fact is MANY a/v stores have CRAPPY power too and the smarter dealers invest in their "house" too so that they can demonstrate equipment at its "least degraded" level of performance. In contrast crappy big box stores often have crummy looking / sounding equipment even if it from a "high quality" manufacturer.

When TVs do not get good juice you honestly will see random "sparklies" or noise. When sources do not get good juice the signal can suffer from things like insufficient gain, failing to get a nice consisten lock on HDMI signals, increased local RF / EMF noise and general loss of dynamic range. When amps do not get good juice the noise floor is often raised significantly, sometimes because the "bad" power has a whole lot more RF than it should AND/OR because the amp working extra hard to try to amplify crud instead of the "good" input signal...

The safety / protection / device longevity is pretty much worth the cost of devices alone and even if you are not a super critical viewer / listener I would strongly recommend good line conditioners for that reason.

Even if you have a top notch utility and a perfect house the power system is still grounded to the earth. When lightning strikes the ground close to your home, that ground path can go right to the third prong on a grounded system and to one of the other prongs on the two prong systems. I have not seen any evidence from a reviewer that definitively shows an improvement in either sound quality or video quality when using a power conditioner. I also avoid all the snake oil sales pitches out there but still have my equipment protected the best I can afford.

XenonMan,

I've been using a Shunyata Triton and Typhon combo for the last month. The difference in sound quality is palpable. I won't pretend I fully understand everything that's going on in this conditioner, but I'll confirm it makes a HUGE difference in SQ -- and not just to my confirmation biased ears, but to those of several friends who have commented on the before and after difference. And it's not like I'm using crappy gear, either.

Here's a review of the Shunyata combo by Mike Fremer of Stereophile: http://www.shunyata.com/Images/Reviews/MichaelFremer_012012.pdf

Although a lot of people respect Michael Fremers and his way out there reviews, I usually read them for the entertainment value of snake oil sales. He gets paid a lot of $$$ to "review" this equipment and I think his reviews reflect that fact.
