DR-3 at 4 ohms is 600 watts per channel at .1 THD and 120db S/N.

Lonnie....to replace the XPR-1s with a DR-3 is tempting.......  |

Remember, when you're running a high performance SMPS, the need for the these big banks of filter capacitors is negated. They look pretty, but they are not necessary when you are recharging the main filter capacities at 50,000 times per seconds vs. 60!!!
The current delivery is much higher with the SMPS and it does not sag under load or low AC line like a conventional transformer does.
Low frequency transformers are rapidly becoming a thing of the past.
Just saying...

So, Dan, new DR-3 versus my old MPS-1 for my LCR? Which way do you go? :-)

As a former XPR-1 owner I can't wait to check them out!

As an XPR-1 owner, I’ve done a Ronco,,,,,,,,  Hopefully I won’t need replacements for a Very Long time! |

This is very nice news BUT, where might this setup be? DC-1 DC-2 and Mini monoblocks.  Lets get a Podcast with just a few bits of news and updates. We don’t need firm dates and what have you, That doesn’t go so well,,,,LOL. But its been some time now. Maybe a hello from everyone at Emotiva, a joke or two and some soft shoe. 😋😁
Perhaps a Live Birthday wish from the gang. 😎 |

The VAST majority of high end/high performance amps still use large linear power supplies. Why do you think this is? Sure, SMPSs are more efficient and run cooler, but I would bet my last dollar that the biggest motivating force for Emotiva to go to SMPSs is to save on shipping costs and the associated damage that often accompanies heavy packages, NOT for a performance advantage. |

BUT THERE IS A PERFORMANCE ADVANTAGE; MUCH BETTER EFFICIENCY.Russ |

Just looked at the Audioholics amp article and they make several mistakes. 'D' amps are not 'digital' but are really analogue. The first 'D' amps were made Years before 'digital' anything made it to the consumer market. And while they tout people on to the high efficiency, that is at full power. Efficiency at useable power levels is lower. And while this is beyond the scope of the article, using the B&O data for an example, while the amp is rated at, for eample, 250 watts, that is for only 30 seconds or 60 seconds. FTC power is much less. en.wikipedia.org/wiki/Class-D_amplifier |

For headphone listening that is!  Though everybody's boat gets rocked differently, I'm still not sure how it's tempting to replace a set of XPR-1's. It must be the space thing. But if it was .... why would you get XPR-1s? |

I am just looking....it would be interesting to give it a test run for the 30 days.....some feedback is the Sound Quality of the DRs is better than the XPRs.....again not married to anything.... |

Yes, its a space thing! 😋 I have a space/office at work that would most likely love this setup. Not loosing the XPR’s my friends. 😁🎶 |

I am thinking of building a 2-channel Rig with twin XPR-1s and sliding in the DR-3 into my HT system.....

Nice !
XPA DR-1 Power Output
600 watts RMS 8 ohms, less than .01%
1,000 watts RMS 4 ohms, less than .05%
1,500 watts RMS 2 ohms, less than .075%
