It's a placebo effect. Just imagine more bass, you'll hear more of it. I guarantee you.
I've owned a lot of Emo amps. They ALL sounded EXACTLY the same.

yep. "good bass" is a lie and a myth. as long as you have enough watts to sufficiently drive your speakers, the electricity really doesn't know the woofer from the tweeter. really it doesn't ;D

Hi All I've been using a UMC with a XPA5 combo for about 6 months now and they have serve me well. They produce good highs and mids and excellent lows when listening to my music in direct mode which is the best sound without using my power sub. However, I just found a decent deal on 2 XPA1 and pull the trigger on them. Reading thru the forums and found it produces very good lows and gives more headroom but only the mids and highs are benefiting from these amps. I am not getting that excellent bass anymore. Any suggestions on what to do to improve the bass like the XPA5 was producing for me. Welcome to the Forum. I would advise that you double check your connections to make sure your didn't cross your connection polarity on your amp speaker outputs. Also double check your speaker terminals and ensure that both the high and low terminals are properly connected. |

Better just send them to me for inspection.

XPA-1 is capable of more current output thus making bass tighter and more controlled. This is a factor with Klipsch RF-7 which have been measured to go as low as 2.7 Ohm. Less capable amp will distort more at low frequencies which is usually perceived as 'louder'.
Either your preference is not tighter, more controlled bass or your amps are broken. If you have everything connected correctly, call Emotiva.

garden variety cables will not be ideal

Thanks for the quick responses. You guys are quick on here. I'm going to try switching speaker cables today and see it makes a different. I was using monster z2 cable with xpa5 but the terminals on xpa1 are so far apart I am just using regular 12g wires from Fry Electronics. Z2 cables look to pretty to cut them but going have to now lol. I'll keep you guys posted

When you get the new cables be absolutely sure that you do not have them connected out of phase. The first thing that struck my mind when I read your original post was that you have one of two problems. First, I thought you probably have them hooked up out of phase. Second, the XPA-1s are delivering a very tight control bass which you are not used to hearing. If your previous amp was being driven hard on the low-end they may have started to distort, which could have sounded like strong bass output. If this is the case, the output would have been louder but the bass would have been muddy. With an amp with greater headroom, the bass would have been tighter, but may have sounded like the SPL was lower.

Ok bass is back!!!! I guess what happen is I just plug the cable in the highs only and not the middle where it is part high and part low. I got the bass back when I did that but shouldn't it matter cause it has jumpers connecting the positive to positive and negative to negative. I think it's odd that that made a different in sound. Well it's fixed and sounds awesome. Might have to upgrade wires later still don't want to cut those z2 wires. Any thoughts on canare 4s11. If I get those should do a bi-wire config or just make one 11guage connection

If I get those should do a bi-wire config or just make one 11guage connection 4s11 sounds too warm for me. I changed to double run of belden 1310 and it sounded more transparent and dynamic. So, how does the xpa1 sound compared to the xpa5 for stereo? |

garden variety cables will not be ideal as long as your cables are of a sufficient guage for the length of the run and make good contact with the binding posts, you can use any cable you want. sonically, it won't make any difference. **edit** if you feel that expensive cables sound better than cheap ones, please don't argue the point. instead go out and make yourself a rich man!

There is definitely a tighter bass and a little bit more headroom with xpa1 but I don't think I am getting all the benefits yet because I don't have a fully balance system set up yet. For movies it sounds the same to me because the center is doing most of the work. I listen to music thru my apple tv with hdmi so this amp is not really benefiting me yet. Waiting for new xsp-1 and xda-2 to come out:)..... For wires wise I'm going to wait because they sound good for what I have
Thanks for everyone's input
