Singlepower MPX-3 vs. Raptor

post #1 of 106
Thread Starter 
Both the Singlepower MPX-3 and the Raptor seem like outstanding tube amps. Are there anyone out there who have heard both and can compare the two amps?

Thanks

another vote for the zana deux- it really does take senn cans to another level.
the singlepowers i've always thought to have a refined sound, very beutiful, great dynamics, and very involving presentation
the raptor is fast, have great pace and alot more solid state sounding than the rest, i've found it to work well with the PS-1, it's best point of reference is something like a GS-1, but it's a little better imho than the gs-1.

Just a friendly reminder...we're going to insist on civility from all involved in this thread.

As most of you are probably aware, these threads tend to get a bit, shall we say, involved. There's nothing wrong with discussion, and expressing opinions. When it becomes an argument, it will be a problem.

Please keep it civil...thanks.

Both amps are quality products and really need to heard to appreciated. I say this because both brands have a loyal following and sometimes the debate about them can be very polarized. Much like the on going Grado vs. Senn. debate. By hearing them both at a meet, you will be less likely to be influenced by who yells loudest.

Tuarreg, have you read the 6moons reviews on the two amps?

Yup. both reviews were quite interesting, but I don't remember much direct comparisons between the two amps in order to make an informed decision.

I had the Raptor for about 13 days and the MPX3 (w/ upgrades, but not the slam version) for about a month.

Source: EastSound E5
Cables: Grover U4/5s and M-Paths
Headphones: A900, SR225, & HD650

Raptor
I think my impressions of the Raptor were slighted by the source and cables. The Raptor had great speed and separation, but I couldn’t listen for very long periods and not as loud as I would have liked, but the M-Paths did help with this.

MPX3
I didn’t like the MPX3 with the stock tubes. But when I rolled in the NOS tubes it completely changed my opinion. Yet the MPX3 had a slower delivery and not as good separation and slightly lacking in low level details. With the NOS tubes the MPX3 did have a fuller, wider soundstage, and more musical sound.

If you are truly interested in these amps, you need to hear them. If you call, I am sure you could sample both in your home and that’s the best way to make your decision.

If I picked between the two, I probably would have settled on the MPX3. But I preferred the Eddie Current EC-2A3 hands down over both and in the end that's what I got.

Thanks 909. I am going to get a chance to audition a Raptor soon, but I have no idea how I might be able to audition a MPX3 or EC-2A3. Matter of fact, I never even heard of the EC-2A3 till now. Perhaps they will be at a meet in the near future. Meanwhile, if anyone else have any direct comparisons, I'd be much obliged.

Thanks

Just call Mikhail at SinglePower and tell him you want to demo a MPX3. I am sure he’ll work something out for you, but you'll probably have to be patient. The EC-2A3 is an Eddie Current amp. Craig at Eddie Current no longer makes the EC-2A3, but is now making the Zana Duex, which sounds better and is a bit more.

If I was in the market for a headphone amp and given the choices presented and that I’ve heard all I’d get the Zana.

Just read the meet impressions from the 2006 summer So. Cal meet. Here’s the link:

In fact, the Zana Duex is probably one of the best amps I've heard and at the asking price, it's an absolute bargain.

LOL, MPX3 vs. Raptor discussion is as usual limited and turns into a recommendation for Eddie Current.

What's with this general reluctance to post about RSA vs. SinglePower? I'm sure many members have heard both and have an opinion.

Of course, anyone is free to refrain from posting their impressions; no one will know.

I use an RSA Raptor as well as a Lehmann Black Cube Linear and AT-HA5000. I've never heard a SinglePower, but I've heard the Prehead MkII SE and HA-2 MkII SE. I don't think any one of these amps are absolutely better than the others. They each have strengths and weaknesses when paired with different gear.

I would assume this to be the case too with the Raptor vs. MPX3. I would love to be wrong, though. If the MPX3 or Zana Duex is so much better than the Raptor, it would be one hell of a single-ended amp and worth selling all my amps for.

I currently have both amps and agree with Elphas that every amp entails a mix of pros and cons.

Running on Tung-sol 5687s with one Ken Rad, the MPX3 Slam offers a detailed and spacious sound. I find this tube combo to work best with my 650/Zu and K701. However, it is little too bright for my tastes with cans like the new DT880. I would tend to agree with comments that this amp delivers the typical tube sound signature.

The Raptor on the other hand (Tung-sol 5687 with Sylvania 12AU7) provides a more impactful sound that is 'thicker' sounding, but works well for the RS1 and DT880. Again, a different sound that synergises better with certain cans and interconnects.

I am lucky to be able to keep both amps to give me a choice.

It is tough having to make a decision based on other's comments, so trying out both amps before taking the plunge would be the ideal way to go.
