'H' is a rail voltage switching PS, not really an amplifier 'class'. The DR series is A/B, which is FINE.....no need to BS people.

Question: Is there any point reviewing a fully balanced differential amp using only unbalanced inputs?

This will be my next step. Get DR3 - and 1 Single Module for my XPA-Gen3 (which is now a XPA-9). I'll plan to take out the 2 Stereo Modules, and replace it with a 6th Single Module to get a XPA-6.

Question: Is there any point reviewing a fully balanced differential amp using only unbalanced inputs? You would be surprised the amount of people that do this with our DR amps. We get asked all the time if there are still advantages to the DR amps if they are only using the unbalanced connections. |

Sure it’s faster than your Toyota Camry, but you are not getting the full benefits out of it. |

Question: Is there any point reviewing a fully balanced differential amp using only unbalanced inputs? Since he doesn’t really do any testing in this review it’s kind of irrelevant, but his comment about noise makes me wish he’d gone into more detail about what he did to troubleshoot, and was the noise present without input or with his unbalanced receiver hooked up. To your point, he may have shown the value of a balanced connection without really mentioning it. |

Question: Is there any point reviewing a fully balanced differential amp using only unbalanced inputs? Good Question. But I'll GUESS that over 1/2 the owners DO use single ended not balanced. That would be an interesting Survey Question...... |

I own three DR1s and they are dead silent. I had to be his receiver.

I would have to think this amp is best suited for the XM-2, RMC-1L and RMC-1 for obvious reasons but whoever wants to spend their money on it regardless of gear behind and in front of it I'm sure Emotiva doesn't much worry haha.

Chad Right you are! A sale is a sale, even if the amp ends up in the PA system of a bar somewhere in South Dakota. |

To your point, he may have shown the value of a balanced connection without really mentioning it. The issue I believe is the receiver causing the extra noise. It's my receiver for sure. The amps actually help slightly, even using the RCAs vs XLR. To answer many questioning, no, I could not take full advantage of the DR series using RCAs. But many people will still use RCAs, so not completely irrelevant. I would love to upgrade to a pre/pro at some point, but it's money I can't justify spending currently. I've tried to build my system up over time, focusing on the components that will be more relevant in the long term first. So speakers and amps. You don't usually see technology make huge jumps within 1-2 years like you do processors and display devices. Shoot, I'm still running a 1080p projector. Making the jump to 4k and a pre/pro unit will happen, just gotta wait for the right time when the funds make sense. Then maybe I can enjoy dead silence through my speakers  (although I can't hear anything as it is in my seating, like I said in the video).
Hope that helps!

Fine, I prefer class A even though I hear people suggest that class whatever is more efficient by generating less heat. Power is cheap where I live so what do I care if a lot of heat is generated  @hair nick Really love your videos Nick. Wish you'd explain more about your liquor selection from the bar. I've never handled "hard liquor" well and don't really know what one may mean when describing Brandy as smooth In all seriousness I appreciate your use of your subs sensitivity rating. I recently took a db rating of my subs when the mains were at THX levels. I like my soundstage a little more bass heavy and while mains were dialed in at 105db the bass is now 120 db so ignore the 122.6 db from 10 feet in front of the soundstage while listening to Jazz music.  Can't wait till your next video Hair Nick! |

WHERE I Live, a high efficiency amp may help in the summer when keeping the place COOL costs a bundle.
In the cold season, I wouldn't mind a Low Efficiency amp since it all goes to heat, anyway.
Keeping multiple amps for 'seasonal' use is a non-starter for me. Maybe were I to get a complete SOLAR install, my electric bill would be less of an issue.
My bill last month was for about 250kwH and when adding in gas for cooking only, and not a lot of that, STILL ran over 100$

I ran air conditioning every day of last month keeping an entire 2400 sq ft home less than 68 degrees. My power was less than 50 dollars a month which included running this pc and my system and everything else. Mind you that's running a class A amp. I'm not mentioning where I live because I don't want Lib/Dems moving into my area driving prices up promoting their failed politics and green bills. I'd rather them stay in their area living their convictions as well as narrative. The grass is greener on your side!!! |

Why would using unbalanced be a problem? Many people don't have balanced but want the DR for other reasons. Unbalanced and Balanced only helps connection versatility and hurts nothing. I wish the reviewers would get how these amps work, right. It is a Class H power supply rail system, and class AB amplifier stages. Amazing no reviewer gets it right. It is after all right here. emotiva.com/collections/amps/products/xpa-dr3. Not like it's a secret. My thing is if you don't get the technical right, don't do the technical. Very easy honestly. |

Actually Emotiva is errant in calling their DR amps Class H. They are really Class G and yes I realize that these two classifications deal with power supply rails and not amplifier biasing. Here is a statement I found - Class G amps employ several power rails at discrete voltage steps and switch between them as needed. Instead of providing multiple rails, class H amps track the input signal and modulate the voltage on the supply rails. The only Class H I ever heard of was an amp designed by (who else) Bob Carver.
