I compared XPA1s to Sanders Magtech Monos about a year ago. I can say for sure that the high power of the Sandes amps (1600 watts) was more resolving than the XPA 1s. However not so much so that I wanted to spend 8.2 K more to get it. Now Emotiva is offing nearly the same power at an upgrade price I myself can't refuse. Consequently, I have my pair of XPAs for sale in the Emporium. If anyone is interested, they are just back from Emotiva, clean bill of health all original packaging.

Please elaborate on higher quality. You mean a nicer case? Shinier switches? Please explain.. not sure. don't know what exactly what has been compromised in the current design / choice of parts to make it value for money or cheaper to produce. Im not a diy guy but if u are and genuinely interested to know about higher quality parts, can post this question in diy forums. I recall diyAudio did have people who self upgrade / modify the XPA1. Oh, one thing I can see is the connectors on XPA1s, can definitely use higher quality ones, eg the wbt 0710 series. whether or not using these parts can lead to better sounding gears is of course a separate discussion. There are a number of good reasons why Emotive is very open about "numbers". They reflect performance and design quality. It's hard to say how much time and money you'd need to invest in modifying an XPR amp to see any improvement. All amps have some compromises, and I bet you'd need to invest quite a bit of money to improve it measurably (more expensive caps doesn't always mean 'better'). |

Class A output question? So the xpr-1 is a class a/b amp with a class h power supply.
Presumably it's amplification section runs in class a mode at some point. Does anyone know how far that is?
I guess I'm figuring its fairly low since the class h power supply is causing the rails to track roughly with the input?
Not that I think that it would change my purchasing decisions, but more out of curiosity.

Not that I think that it would change my purchasing decisions, but more out of curiosity. Regarding Class A: To answer your Class A question, its 0. The XPR-1 is pure Class A/B from the 1st watt You can read Dan's explanation on the class H PS here: emotivalounge.proboards.com/index.cgi?action=gotopost&board=amps&thread=24997&post=417104 |

I know the dependencies between increasing electrical horse power faculties and a clean undistorted stereo playback in higher db regions. This is an argument pro XR-1  To be honest I am interested in an amplifier having none noise floor over the complete db meter range. Is there some ground snorring, hiss etc. or is it like dark silence when the amp is alive, and underlying music signal takes a break some seconds ? Ok the preamp may be also taken into consideration. What are your experiences ? |

The preamp is important. I used to run a Parasound P3 and for what is was it sounded pretty good. However, when I put an Ayre K5 XE MP in the chain things were a lot smoother, much less fatiguing, so much so I won't let myself try the flagship Ayre preamp because I don't want to have to buy it. The Ayre took some "etch" out of the XPA 1s.

What are your experiences ? My experience is with the xpa-1's . They have a jet black noise floor, absolutely no hiss at all even with my ear as close to the speaker as possible . no noise during silent interludes within the music either, even at extreme volume level. no sound other than that recorded on the media. A wonderful amp , i can only assume that the XPR-1 would perform identically with respect to noise floor and superior in the dynamic range. |

i wonder how XPR-1 will fare against Classe CA-M600 monoblock. Based on the specs, both sides have different strengths, but in terms of price, its definitely a large difference.
Just wondering how the SQ will be like when comparing with these two.

Arrrrrgh. Might be a bit before I can get my XPR-1s set up. I have nobody to help me, and a bad back. Everyone is so busy with the holidays, none of my friends or family have a few hours to spare. Frustrating. I really cannot risk it though by myself In 1998 I suffered a horrible splitting upward of my groin (lifting a 200lb TV)...like my belly opened up. Walking funny during recovery caused my back to go out. AND I was born with Hernias...so lets just say I have genetic muscle weakness in the groin & back...so I don't think I should be hoisting 100lb amps by myself.

I noticed that these amps have a minimum ohm recommendation of 4 ohms. I thought that these bad boys might be Emotiva's first amps that break into the 2 ohm stable category. Oh well, maybe the XPA-1L will be 2 ohm stable.

My guess is highly organic and chocolatey, with midder mids over a wider soundstage with lots of air around each voice and instrument and with pinhead imaging. But I could be wrong. |

Oh well, maybe the XPA-1L will be 2 ohm stable. Oh they will handle 2 ohm with no problems, we just don't list the specs for it. It is one of those things. Whatever impedance we list, people will always want to run it lower.  |

So it's got the capacity, you just don't want to market it as such? I guess people will try anything, but it seems like it should be a proud moment for Emotiva.

But I could be wrong. And a velvety smorgasbord of low-mid, mid-high-low, and low-mid-mid delineated "air" of detail of course... |
