New P10 added on clean line


#1

So - recently I bought a P10 - and the question comes up a lot about ‘what if my power is good now?’… Well I think I can answer that…
My power without anything connected was @ 1% THD sometimes dipping to .9% THD… voltage is a fairly consistent 123… With the P10 - that of course goes to .1% THD & 119.9 or so voltage to my components.

Short story - system sounds the best it has ever sounded. I have the following hooked up - DS/Cary slp98p tube pre /martin logan descent sub/ sunfire signature amp / magnepan 20.7. The sunfire is a bit different in that it has a Bob Carver ‘tracking downconverter’ power supply… which supposedly tracks the signal and either boosts or decreases based on demand. It is Class AB but the power supply is a bit of an anomaly…

Here is what I noticed: Things sound a touch quieter/ a bit more real / bass seems better and at times before it seemed like I would notice a sub ‘thump’ every now and then during playback… Not any longer. I only have my sub boosting the frequencies 25hz and below and the Mags do pretty well… Soundstage definitely seems wider and everything just seems to have a more organic feel to it… Everything that audiophiles love. And to the stupid part - Is it bad that it just makes me feel good having everything connected to pure power? It just feels good…

Highly recommended… Thanks Tim.

Hi, Tim. Would love to hear about your experience with the 20.7s. I’m considering them, but can’t hear them locally, even though there is a Magnepan dealer (which doesn’t have them) and I’m driving distance from White Bear Lake (their listening room is a war zone right now). Anything you can share, especially in terms of comparison with 3.7i (which I have spent time with).

I too was stunned when I introduced the P-10 into my system. It was as if I improved all of the electronics in my system. The bottom end was mode defined and dynamic the overall sound became very lush! It was the biggest single improvement to enhance the sound that was not actually a component part. My power is not as clean as yours going in but of course is going out of the P-10. A must have for every true music lover.

yes… dynamics as well as you stated sixpack… forgot to mention that… the system had a bit more jump in my opinion…

oh my … I absolutely love the 20.7s… To me - they are in another league compared to the 3.7… I don’t really need a sub… I had the sub - and decided I would run it a very low volume - but the sub has a bass volume at 25hz which is what I use… The tonality of the bass and the lowness of the bass is all there without the sub…but My room is 30x17x8 … which works incredibly well as I have them off of the front wall 10’ … This isn’t definitely a must - but very nice. In every case I tried to knock the bass when I listened to them before purchase… and in every case came back very happy. To me - they give you everything the 3.7 has but with added mid-bass and lower bass weight… which really adds to musical enjoyment. The textures of the instruments really seem to come alive with this as well - and they are much more dynamic as compared to the 3.7… I actually listened to them in Evanston Ill @ Audio Consultants… Then had to buy them somewhere else!! (not my choice - theirs) …I had listened to Wilson Alexandria XLFs, Sonus Faber Strads, Macintosh Line Arrays, and B&W802D2s… All more expensive … but I like the 20.7… If you get them - you will love them… Let me know what you do…

just an fyi Christopher … if you go to audioaficiando - I wrote a fairly extensive review in a thread there under the magnepan category and a thread that may just be titled ’ ‘20.7s’ … It will be an older thread… but you should be able to find it - and opinions from other users there as well…

After reading this review I’m going to have to check these out.

Why not consider these bad boys?

I’d love to hear those speakers, despite the fact that they’re outside of my budget, and too large for my room. Heading to a local dealer today to check out the 20.7’s and the 30.7’s.
Edit: No longer any Magnepan dealers in the Denver area. Bummer.

here is a good thread for multiple reviews of the 20s - mine included in this link… https://www.audioaficionado.org/showthread.php?t=13018&page=20

back to the P10 … So last night I sat down and put on Coltrane Ballads and the Coltrane/Johnny Hartman album… Is there any bourbon in the house??? Oh wait it is a work night… dang… I think the P10 does bring some serious JuJu to the mix… (Paul you can use that in a marketing campaign… :slight_smile: ) .

Nice to know, that even if one’s power is fairly decent, these regenerators still make a difference in SQ.

Thanks for your feedback.

Great review timm. I called Magnepan and they are trying to arrange for me to meet with one of their customers in the area who has a pair of 20.7’s. I’ve owner open baffle speakers in the past (Apogee Duetta signatures and Audio Artistry Dvorak’s) and love the open boxless sound they produce. Been contemplating some Spacial Audio open baffle dynamic driver speakers, which I heard at RMAF, but would love to check out the Maggies as well.

Having fallen in love with my Maggie 1.7i, I can’t wait to upgrade to at least the 3.7i.
