XPA1 GEN1

[jimlazaro]

Hello monoblock fans. I would like to know how many of you are plugin your XPA1 to the Emotiva CXM-2? Is it good or better straight to the wall? I'm short of wall outlet for my other source. So I'm thinking to get the CXM-2 for my XPA1.
Need your advice.

My XPA-1's work just fine with the CMX-2

My UPA-500 in another system also has a CMX-2

If you are not experiencing any problems such as buzz or humm plugging directly into the wall then scip the CXM-2. If you're having problems then tey the CMX-2. 

Disclaimer, I have one for each of my set of monoblocks, and no I didnt have any problems just wanted to free up a socket and got a good deal on them.

Thank you guys for replying. I'll do then the CMX-2 since I need the other outlet for my other source with CMX-6.
I just got the XPA1 Gen1. I'll try to replace my XPA2 Gen2 and see which one is better amp/sound etc.
My other source was.
XSP-1 Gen2
Stealth Dac1
Sp-1 for the phono(but did not setup yet and didn't try to my TT)
Laptop using JRiver flac files
Together with the laptop Audiophilleo2 Mk11 with Purepower.

Neither the CMX-2 nor the CMX-6 are "power limiting". You'll be fine...

Unless your utilizing two systems for TT use the SP-1 is redundant because the XSP-1 has a wonderful phono preamp. I actually believe its the same one used in the SP-1 and XPS-1.

I have my XPA-1's plugged directly into the wall socket. I have my HT set up with an XPA-2 and XPA-5 into a CM-2 though. Never really noticed any difference either way. Hang on to your XPA-2, they are going to be harder to come by now that Emotiva changed to modules and switching power supplies....or you can sell the odd man out in here!

In the last few months I have seen Emotiva Gen 1 and 2 amps selling for as much as they did new.

Sort of depends on the rest of the system. If you are working into low sensitivity speakers demanding power, and perhaps into a larger space than you may notice a power conditoner limiting current TO the amp and overall hurting rather than helping. I've had only limitied luck plugging amps into power conditioning devices. Sort of sucks the life out of 'em.

Call an electrician to drop you a dedicated line for the amps.    That's a real good move.

[jimlazaro]

Thank you guys for advice and reply. As of now Im using the CMX-2 on my XPA1 both.
I want to ask you what experience when you have your XPA1 to your system. I have and using before my XPA2 GEN2.
I noticed when I'm listening to XPA1 GEN1 on my system. I noticed that the center voice was not there anymore. But the details,base,mid and high was really nice. But I'm missing the center vocal or voice.
What do you think I'm missing on my setup?
I just did swap the XPA2 to XPA1 and everything was the same. What do you think?

[frenchyfranky]

What do you mean by missing the center vocal? The XPA-1 as the XPA-2 work on the complete audible frequency spectrum. You must not missing anything with both of them.

[jimlazaro]

What I meant was when I'm listening and sitting in the center of the chair when I have my xpa2 I heard voice singing in the middle or front not in the side of speaker. But now when I swap the xpa1 and listening in the same spot middle. I didn't hear voice singing in the front/middle anymore it was on the side of the speaker now. I did move my speakers and still I didn't get the voice in the middle.
I'm sorry I might you get confused what I'm talking about the center or voice singing in the middle not on the side of the speakers.

These past two months I've switched many different amplifiers in and out of my reference system. I think what you are referring to is the center image from a stereo recording. Believe it or not when I change amplifiers, I usually have to reposition my speakers to create that sweet spot again. Try to toe or angle your speakers a bit in towards the sweet spot. Speaker placement is extremely critical to obtaining an accurate Center image. But once you get them right they will sound amazing!

Also make sure you don't have your left output going into your right monoblock amp, etc. I've done that before.

[jimlazaro]

Thanks for your reply. Yes I did all placement of the speakers and I didn't get the right words you mentioned was the center image. So I'll double check also about the output you mentioned from my xsp1 to monoblock input.

[jimlazaro]

By the way are the XPA1 GEN1 has left/right input? Sorry for the newbies quetions.

[jimlazaro]

I'm using XLR balanced from Xsp1 gen2 to XPA1 gen1.

Your speakers are OUT OF PHASE.
Swap the speaker wire on ONE of 'em and I think your image will return to its normal, robust level.

I think you got a phase problem. YOu hooked the wires up the wrong way making the signal out of phase. Switch one of the wires on only one of the speakers and you'll probably hear the voice in the center.
Check your speaker phase here under the section speaker phase.

[jimlazaro]

Guys I was confused when you saying switch only 1 speaker to what? I just followed what the positive and negative on the amp. For example left speaker red wire+ to the red positive of the xpa1 binding post and so on....so what you saying swith the speaker wire to where?

[leonski]

It would appear you swapped a + and - wire to a speaker.

Before doing ANYTHING else, listen to a bass heavy passage. Than swap. Does bass go away or improve? Leave wiring where the bass is best.
That should be back in-phase.

Yeah the speaker wires that go to one speaker. Just swap the red and black on only one of the speakers. So put the red where the black goes in to the speaker and the black where the red goes - ONLY ON ONE END (WHERE IT GOES IN TO THE SPEAKER).
