Welcome to the Lounge! I wonder if the problem stems from a power conditioner that is current limited by design. At any rate, glad to hear you found the answer and can now enjoy your gear.

The timing of this post is very good. It has been a long while since someone has posted about the huge difference it really makes to plug the Emotiva power amps directly into the wall outlet. For some reason, many new Emo amp owners are reluctant to heed this advice -- until someone like you posts on the Lounge. I guess seeing an owner posting the importance of plugging the amps into the wall outlet makes it real.

Welcome to the lounge ;D I'm happy that you got that problem resolved. Lonnie, the chief engineer for Emotiva had previously advised that Emo power amps and subs should be plugged directly into the wall socket. They already have surge protection built in. He also warned against using power conditioners as they could limit current output and affect the performance of the components. Your experience is solid proof that we got very good advice. Happy listening

This depends on the power conditioner, surge protector or even power strip being used as many will limit power peaks affecting sound quality especially bass and headroom, BTW UPS systems are the worst.
I have auditioned many power conditioners and found many to poorly affect sound quality however others with good high output outlets have no poor effects at all and can have an overall improved sound quality. As usual it's best to experiment to find what works best.

Happy listening I want the Science behind this explained, please. According to Lonnie, many power conditioners limit current to the power amps. I have also heard (but I have no personal proof or experience) of some such devices that have wiring that were out of phase for some inputs that affect component performance. Someone with an engineering background is better able to explain the science behind all this ;D

I have found that the high current outlets on both of the power conditioner/surge protectors that I use have no ill effects on the sound in my home theater as opposed to being directly plugged in to the wall. Living on the Florida Gulf Coast demands that I use surge protection, is it necessary? maybe, all I know is it give me peace of mind, and again I don't hear a difference either way.

I recently purchased the xpa-2, erc-2, and the usp-1 to replace my marantz 6000 ose cd player and NAD c270 power amp that I've had for 10 years or so. Upon listening, I found it very detailed in the highs (almost too bright) and in the mid range, but it was lacking bass extension. I could hear the bass detail, but it was restrained and lacking in any real deep bass. After hearing so much about the newfound bass extension and detail that the xpa-2 has brought to so many other people's systems, I thought maybe the new gear just needed time to warm-up and burn in for a few days. So about 30 days later, still no bass extension. This is after checking all connections and swapping cables, etc. After reading almost every thread and review I could on emotiva gear looking for a solution, I finally came upon a thread that I had read before I had made my purchase, regarding plugging the xpa-2 directly into the wall and not into a power conditioner. As it was, I had all my gear plugged into my rotel 900 power conditioner. The rotel's amp outlets are rated for up to 1400 watts. So, that night I plugged my xpa-2 directly into the wall and voila!; beautiful balanced, deep, tight bass. The highs also became smoother, but still extremely detailed. The sound that comes out of my B&W 684's is nothing short of superb. There is natural mid-range and highs, deep, detailed bass, amazing soudstage and a musicality that has me tappping my foot and listening and purchasing more music than I have in a long while. I have to say if it were not for the Emotiva Lounge, I would have been a disgruntal and frustrated former emotiva owner. As it is now, I am an Emotiva believer! Thanks! Good to hear you figured out the problem. Now all you have to do is sit back and enjoy!

Yep looks like you have the PF-60 as I do, I prefer my amps plugged into my PF-60's high current outputs and have no ill affects from it.

My APC AV H15 also has a high current section but I plug my UMC-1, BRP and CD into that section. My subs and amps are plugged into my 20A outlets. I have not done any comparartive listening. So I really can't tell if there is any difference. But all my components are getting all the amperage they need ;D

I know this is off topic, but I noticed you have a Panasonic DMP-BD10A. Have you had any blu-rays not play to date? I'm just wondering if I should have kept mine instead of passing it on to my brother. It is still today one of the best looking blu-ray players ever sold that is non-BD Live.

Either way, 110v or 220v, ultimately it's converted to DC current.

I have the same response living in Louisiana. In the past, I've lost too much equipment without power conditioners so I use them now and haven't lost anything for several years now due to power spikes.

i use my power conditioner only on my pre-pro, cd and bluray players. up until recently i have plugged my xpa-2 and xpa-5 directly into the wall. i now use the cmx-2 for the 2 channel amp. i can tell no difference but i like the added assurance of protection from all the nasties.
as for current draw, i have the power amps each on a separate dedicated 20 amp line. tchaik...........

No I have never had one not play which has surprised me since it is one of the very early Blu-ray players, it has the latest updates but they were from a long time ago and I am sure no more will be available. I have been very happy with it.

I had my XPA-1's plugged directly into the wall but a couple of months ago got a CMX-2 unit for them instead. Lonnie said there is no current limiting on them so it was fine to use this for the XPA-1's. I don't hear any difference in sound but then I don't play anything at ear-bleeding levels. ;D The CMX-2's sure do look nice and are built like bricks.

I'll keep my eyes open for the CMX-2's at Emofest.

I want the Science behind this explained, please. Current limiting and/or drop in AC voltage (poor regulation) A good conditioner does neither of these things. ...and keeps hair soft and manageable.

Don't get a false sense of security with the CMX-2. It is not a surge protector. It's a line conditioner. A very nice one at that.
