EMOTIVA XPA-1 OR XPA-2 for Martin Logan speakers

post #1 of 22
Thread Starter 
Hi,

I am in need of a new 2 channel amp for my HT/music setup and own martin Logan ReQuests as the R/L speakers. If price is a secondary issue after sound quality which amp/amps would you get for those speakers; XPA-1 or XPA-2?

Both seem to be beasts with plenty of power but which would be also more detailed with the MLs?

Any ideas?

The XPA-1 seems like it's a little more beastly and probably the best choice of the two IMO. But you'd need two of them.

My current 2 channel ap is a PS-Audio 500 watt per and it has too much power for the ML and it would go into defaut once in a while. The last few days it had gone into default mode far too often. I've been interested in the Emotiva amps for a while now and would have bought a set of the xpa-1s if they had been available when i needed a new amp. I set up the PS Audio again and now it is not going into default. So for now I don't have to spend another 1800 bucks on a 2 channel amp.

Sensitivity 90dB/2.83 volts/meter
Power Handling 200 watts per channel
Recommended Amplifier Power 80 - 200 watts per channel
Impedance Nominal: 4 ohms; Minimum: 1.2 ohms

The XPA-2 will have plenty of power to drive your logans.

I really like my XPA-5 though.

The xpa-1's would certainly do the trick and sound great doing it. They happen to be on sale for the rest of today anyways as well. I have an XPA-5 that I use for my surrounds now, but I had it driving a pair of Thiel 3.6's as well as a pair pf Magnepan 1.6qr's just to test it out. It does a great job on both.

How about the FACE F1200TS ???

One of those has 1000W/ch into 4 ohms and that will be 1/4 the price of two XPA-1s (if you buy mine that I have sitting around, fans are modded already )

The XPA-2 should be more than enough. 500w/ channel at 4ohms. The reason I would go with the XPA-1s is looks. Monoblocks are cool looking and a conversation piece if setup in front on little stands. I don't know if it is worth $1000 more for that though. I can't see you ever needing 500w let alone a 1000w/channel with the XPA-1s.

Let us know how you make out.

I've ordered a pair of the XPA-1 amps and they are scheduled for delivery today. I discovered yesterday that my current speaker cables are not 'wide enough' for these amps. The + and - posts are 13" apart. I will be using plain 12 gauge with out ends wire until the new Bettercables arrive early next week.

He seems to care for that kind of crazy advice He opted for the 1000W, its good to know why will never use 90% of that head room

maybe he will post how 12 gauge wire wasnt as good as his $300 speaker wire

LOL. Love reading your posts. Maybe he thought they would look better on little stands instead of one amp in a rack. Hell if I had the money I might but them, but I am nowhere near that problem. If I did, at least I would know I don't need anything even close to that much power!

Bettercables; local, good quality, reasonable prices. I knew my little comment about my temporary wires would bring out the nimrods! It did.

The amps sound GREAT! My MLs have never sounded this good since I bought them. My back is hurting since these amps weigh in at 76 lbs each. At least I had a dolly to move them off the porch. However one of amp's LED meter is not working; ug, this probably means more moving, packing shipping back etc. It lights up but does not 'move' as the power increases.

Penngray is a Mesopotamian monarch? I thought he was Canadian and not nearly that old.

There is a switch on the back of the XPA-1 to turn off the meters. I'd check that first. Odds are it got turned off.

That was the problem. I called Emotiva who told me about the tiny switch on the back. Their customer service is top draw as is BetterCable's by the way. My back is very happy!



No sign of any snake oil yet, just made in China parts but hey my Rotel 1570 and OPPO BDP-83 have that in common. The OPPO is assembled here, don't know about Rotel or Emotiva.

The amps do get hot but not as hot as my Aragon 2 channel amp did. By the way in spite of the rated power requirements of the MLs the company has always recommended big honking amps for their speakers [my generation of MLs] and the Emotiva amps are the first affordable beasts I've run across. The XPA-1 model certainly has enough power and they do bring out more over all dynamics in my ReQuests. The sound is different, than the PS-Audio 500. So far I'd call it more robust, yet still detailed. I'd say the best quality recording I've played so far was the SACD of Bob Dylan's Blonde on Blonde and it sounds the best I've heard it. I have 28 days left to audition them and I have listened to more delicate recordings yet; for me that will be the keep or send them back test. I did listen to Diana Krall's The Girl in the Other Room and I was pleased with how it sounded. On both the Dylan and Krall SACDs the sound was some how more complete. I have many SACD/CD/DVD-A/DVD/Blu-rays to run through the Beasts before making the final decision. I bought these based on what the folks at Secrets of Home Theater and High Fidelity wrote about them and Emotiva in general. They lead me to OPPO and other equipment as well; I turst them. Other sources influence me as well including what many at this forum have said about Emotiva.


At this moment I can give a 'qualified' YAHOO to these mono block beasts but I still have much listening to do. The price is right, I got them 300 dollars off on sale and they drive my very temperamental speakers like champs; so far any way.

Just curious: What do you think will happen in the next 28 days that hasn't happened already? I've owned my Emotiva amps for over a year, and they sound exactly like they did on day one.

I am just taking my time auditioning them. Which Emotiva amps do you own?

I bought a pair of the XPA-1's when they were on sale and really do like what they do with my Thiel 3.6's. For the last 14 or so years I've been driving them with a Threshold SA/4e and I have always loved the sound that combo produced. The XPA-1's produce quite a bit more power than the Threshold though and that difference in noticeable on movies...not so much on music. I am impressed with the emo amps...they are a great sounding quality piece of gear.

After using them for a couple of weeks now I can say I agree with your assestment except that I notice a good difference with music. My Martin Logan's seem to sound better all around with the dependable power of the XPA-1 amps. My PS-Audio 500 watt per 2 channel amp could not handle the peaks and would shut down. Also the bass coming from the MLs is noticebly better. I can say that I wish I they were available 3 years ago.

There must have been something wrong with the PS audio amp since they can only handle 200 watts max.

I bought a pair of Emotiva xpa1's on audiogon, for $1250. And just before that I ordered an xpa2 for $679 from Emotiva, I haven't compared them side by side yet, but I'm wondering what is the better bang for the buck. Is there a huge sound quality difference? And I'm ONLY using my amps for HT.

Should I sell the xpa2 or sell the monoblocks.

I already have an xpa5 with a marantz 7005 pre. When I compared the 1's with my 5, the sound us just as powerful but a little refined. Is there a $500 difference in sound that's worth keeping the monoblocks?
