Singlepower MPX-3 vs. Raptor - Page 2

post #16 of 106
I can testify that the Zana Duex is a great sounding amp. In fact the Zana and the Ear HP4 are the only amps that could tempt me to move away from the SinglePower brand, and the Ear HP4 is a $4000 amp. I should point out that I have never heard the custom "Blackie" amp that was at the NY National meet, and that may well be another temptation, probably an expensive one.

That said, the one thing that would concern me about the Zana Duex is the lack of "tube rolling" possibilities. Although it may not be that much of an issue since it sounds so good with it's stock tube array.

Yes, but what fun is that? It might as well be solid state.

My PPX3 Slam just arrived. I already had 12 tubes to try in it (though 7 of them are the same type of 7N7). Fun fun!

I was looking for an amp to go with my K340s at the LA meet. I zeroed in on the SP amps and the Xana Deux as my favorites. I tried the Raptor. It just didn't sound as rich and lifelike through the K340s as did the SPs and XD. Of course, that's my brain. YMMV. After listening to Borat's PPX Slam, I knew that was the amp for me.

IMO...

Raptor - Neutral sound but still ever-so-mildly 'tubey', tuberolling does not have as dramatic effect, good for someone who likes the sound of his associated gear and doesn't want to change it OR someone who prefers to tweak from other than the amp side.

MPX-3 - Much more colored sound, what more people would consider tube-like, usually requires (expensive) tuberolling from the stock compliment to sound best, good for someone who wishes to tweak system sound on the amp side.

I'm sure either can power virutally any headphone, past or present, with the only exception being the AKG K1000's (and some people claim they can do that too).

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.
I have 2 Tung-sol tubes. I dont see any number on the tubes said '5687" or "6SN7". Can you help me to identify ?

the 5687 is a much smaller tube with a different base (9 pin mini) like the one shown here:

The tung Sol 6sn7 is much bigger with an octral base:

Thanks. Then I think my Tung-Sol are 6SN7. It sounds similar to 6SN7EH on HD650. But EH makes GS1000 sound much quieter(thinner) than Tung-Sol. For HD650, is Tung-Sol better than EH ? I heard 6BL7 from Kan Rad is the best for HD650.

What headphones will you be using? I think that will play a big part in your decision. The Raptor does a nice job with higher impedance phones like Senns and Beyers but it struggles with Grados and other low impedance phones. The MPX3 will drive most phones very well (not counting the K1000 which it can't drive). If you choose the MPX3 I'd recommend you use get one with either the 5687 or 6bl7 output tubes as I feel they offer large improvements in the dynamics department.

I will be listening through the HD600 and I have heard that they mate quite well with both the Raptor and MPX3. Two more amps have entered the arena from the PMs I've been getting, so I'll add them to the mix: BADA PH12 and the Zana Deux (quite a bit more expensive and hard to get).

Thanks for the input.

to be honest there are somany different options on the mpx and somany different mod's and power supplys for the raptor that having a fair head to head would almost never happen, exp with good enough time in a non meet listening period.

I will tell you this, I own the raptor and heard earl's mpx's and to be honest the house sound from Single Power and Ray Samuels is very close to me one could enjoy either without the politics or fanboyism's...


Gilmore type amps sound like these two but are very airy and some say bright, also the HR amps I heard are even further from the SP and RSA house sounds imo...

not saying either is the best or either is the worest cause I dont have your ears on my head...
try them both yourself and leave the opinions of the fanboys where they belong...on internet forums talking trash about the other..

of course since I have an xp-7,hr-2,raptor,hornet,sr-71,and soon to be B52 (after I find a buyer for my kidney) I would easily be called a RSA fanboy..so there you go ..lol
post #25 of 106
how much for 2/3 of your right kidney?

Auditioning is what I did and it was the best thing I could have done.

I heard it differently, the Raptor and MPX3 didn’t sound similar to my ears and I am certain I am not alone. This is the first time I’ve read someone say they sound the same. No better advise anyone can give than to tell you let your ears be the judge; and you'll have no regrets.

The Raptor struggles with Grados and low impedance headphones?

I use it with the RS-1, HHF-1, HF-1 and MS2i, as well as the W5000 and other AT's. I think they sound very good.

I prefer Grados paired with the Raptor than the Lehmann BCL, AT-HA5000 or any of the Cordas I've tried them with.

The first time I heard the Raptor, it was a pre-production model. I'd agree that it seemed to struggle with low impedance cans (specifically Grado PS-1, SR225). I've spent some time with a Raptor as recently as last summer (SIGH...it's fall!!), and it handled the Grado PS-1, HF-1, SR325i, and GS1000 very nicely.

I've not spent time with a newer generation SinglePower, but they certainly have a strong following on this site.

I have not heard the Singlepower amps, so I can not contrast for you.

I will second that the Raptor drives the W5000 and the UE-10pros with aplomb. I go back and forth with 650s and the W5000 depending what mood I am in. UE-10s might as well be welded to my Hornet.

Proponents for both sides here, and being unusally polite on this tread, Congrats to both sides for a nice discussion.

I agree...thanks to everyone for making it so.

As is RS Audio's following certainly strong here too coincidently. And both camps tend to be very passionate about what’s pleasing to them and brand loyal as well.

When I started my amp search (about two yrs ago) I thought without question I’d get a Raptor based on the opinions stated here and else where. Then I thought it would be wise and won’t hurt to at least consider and listen to another amp. But still in the back of my head based on my readings I never thought another amp (within my price range) would or could be as good as the Raptor. Yet to my complete surprise the MPX3 with NOS tubes was more to my liking and then the even lesser known EC-2A3 made the music seem real and that’s why I got it.
