For those who attended Emofest, what is the scoop on the XPR series, specifically, the XPR-1?
Will an XPR mono block ever come to fruition and does anybody have any specs on power into 8, 4, and 2 ohm loads, along with the size of the toroidal transformer ?
Thank you!

If I recall correctly, the XPR-1 was shown to be 1000 watts. It has a LARGE transformer.
The monoblocks will be a little while away. I was told the XPR-7 and 5 would arrive first.

The monoblock was 1000 watts at 8 ohm and a full 2000 watts at 4. I'm not sure if it will do 2 ohm and if it could I'm not sure if you would be able to feed it the power it would need.
Just thinking back to my college days... What would 2 XPR-1s and a set of Cerwin Vegas do (besided hearing damage)?

Thanks very much for both replies so far....
You know, I am starting to wonder if Emo Corporate Hdqtrs is or will eventually receive royalties from electric utility companies?...LOL
Well, I'm an analog kinda guy who upgraded from decade old Adcom gear and now enjoy a pair of XPA-1s with a a USP-1 and an ERC-1 for 2-chan listening. And, we watch TV and movies this way too.
For me, the upcoming debut of the XDA-1 and XSP-1 are for sure future purchases. The x-series subs may be deserving as well.
Honestly, I haven't been into home theater since Dolby Pro Logic days but maybe I'll venture back into it. Maybe an XMC-1 used in conjunction with the on-hand XPA-1s which could be moved to surround sound duty and then purchase a pair of XPR-1s for the mains.-- sounds overkill don't it? LOL LOL LOL
As far as speakers, I run a pair of decade old Newform Research 645 dipole ribbons and the Emo gear has breathed new life into them. They are very transparent while dynamic, 76" tall, and do light up my great room per say which is 24' X 26'.
In the 'past', the manufacturer of my speakers has advocated a home theater set-up w/o using a center channel speaker for home theater apps as long as the processor has a phantom mode of operation. Due to their transparency, I would agree
Well, all in hobby fun. In closure, I appreciate any knowledge gained from Emofest on the so called XPR-1 mono blocks.

Definitely do your research before you start scrapping those XPA-1's ...  I was at Emofest and after talking to Lonnie about amps...my friend decided to replace his 2- XPA-2's that he was using to bi-amp his 8.3's with 2 XPA-1's....the new XPR series are clearly powerhouses....but they are H Class amplification which is great power, efficiency and temperature control....but its pretty hard to beat the sound quality of an A/B Class amp like the XPA-1's....Just something to look into....I almost get the feeling that the XPR series reigns supreme in the high power home theater that many Emo customers desire...but home theater allows for a lot of forgiveness when it comes to sound quality...especially between amp classification.... |

Thanks for the feedback Joe... Personally, as far as myself, I have no intention to 'scrap' my pair of XPA-1s--any time soon. Heck, I haven't even hooked them up to a preamp with balanced cables yet--- waiting on the XSP-1 along with the XDA-1 for further potential sonic improvements. I will say this: If I do purchase a set of XPR-1s in the future, I'll most likely 'slave' them into my current system to actually compare them to the XPA-1s and then use my own ears to determine if the Class H mono blocks are supreme, and are keepers during the 30 day trial period. ------------------------------------------------------- stason.org/TULARC/entertainment/audio/general/11-18-What-is-Amplifier-Class-A-What-is-Class-B-What-is-Cl.html"Class H refers to using a Class D or switching power supply to drive the rails of a class AB or class A amplifier, so that the amplifier has excellent efficiency yet has the sound of a good class AB amplifier. Class H is very common in professional audio power amplifiers." |

Ya..I didn't figure you would be scrapping them....Absolutley on the right track with the A to B comparison...or in this case A to H comparison....Its all about our ears...  Good Luck and Enjoy!! |

One more thing Joe:
Since the soon to be available XDA-1 has a volume control, I intend to run the XDA-1 directly to the XPA-1s using balanced cables and then use my own ears to listen...
Next, then incorporate my on-hand USP-1 and also later try the XSP-1 when it become available for another listening trial.
At the bare minimum, I do think the XDA-1 will be a keeper....
All in hobby fun!

The XDA-1 was very interesting. Here's a link to a few photos I took at Emofest....the shot of the 2-channel room shows the XDA-1 being used in that very scenario...with 4 XPA-1's.....and the ERC-1.... I should have pre-ordered an XDA-1 ....I might have a use for one of those.... joelovescoffee.smugmug.com/Other/EmofestGear/13690068_VUktvhmmm more in the name of hobby fun.... |

Joe:
Thanks for sharing your Emofest pics...
We all have a 'big kid' inside of us-- and you remind me of a kid who just visited the North Pole....LOL.-- I bet you're still smiling...LOL
Maybe I'll make the trip next year since it's within driving distance.
