Newbie lsi9 + marantz

albatross

Hi everyone:


I've just bought a pair of lsi9 and i was wondering if the Marantz pm7001
would have enough power to drive my speakers.
And if you got a better suggestion of another stereo amplifier will be very apreciated (less than us$ 1.000):o

thank you.

marantz specs:

That's a solid integrated amp. I've listened to it with a lot of different speakers at an audio store in Des Moines IA. With the high current design it should be adequate for the LSi9's unless you are in a huge room or want to listen at high volume levels.

^ what that dude said.

thank you. On my way to buy one right now

No, don't do it.

That Marantz is on the anemic side when it comes to 4 ohm loads.

If you already have a preamp or have a receiver that has preouts, take a look at the Parasound A23. A much more solid amp, and it wont break your bank.

I've heard that little integrated run Magnepan 1.6's, and it did a fair job. You can't put it in the same class as the Parasound Halo line, and it isn't even close to being in that price range. It's a good solid integrated amp that you could start out with for the LSi9's, and you're going to do alright on reselling it when you want to move up to something like the Parasound Halo line.

What's considered a good price for that Marantz?

dkg999

I have seen them new for $399 + shipping, in the past. Not a piece of gear I keep tabs on, but happen on them when searching for other things.

mightymouse

$399 is definitely a good price for such a nice integrated.:)

Magnepans are probably easier to drive than anything from the LSi series.

Do you own Magnepans? I do. I also own LSi's. Wishful thinking on the "probably".

They're right in my sig.

Maggie impedance curves are usually nice and flat at 4ohms, meanwhile a LSi9's dips down to 2ohms.

Anything else you'd like to add?

The 1.6's are a little different animal than the MMG's. I can drive MMG's nicely with my NAD receiver. The LSi9/7 have seemed much easier to drive in my experimentation than the Magnepan 1.6's. That same NAD receiver will drive the LSi7 nicely, and do an admirable job with the LSi9. It will die on the 1.6's.

Sorry to come off short, and didn't notice the MMG's in your sig.

Most maggies are similar in design and have the same flat impedance curve.

You may believe your receiver is having a harder time with them due to their less efficient design than the LSi's. When I hook up my maggies, I have to almost use double the volume as I would with my Tannoys to reach my usual listening level.

I don't even factor in the volume setting, I'm refering to sound quality.

Back to the OP's question, I believe the Marantz IA is going to do just fine with the LSi9's within the boundries outlined. You can throw around technical specs all day long, but the LSi's aren't that hard to drive, and I'm pretty much convinced that you can get decent sound with a wider range of amps and receivers than most of the comments here would lead you to believe. To get outstanding performance, and get the most out of them, then you need some good source gear. YMMV.

^^ I would have to agree that the 9's are not that difficult to drive. My old 70's integrated by Technics (73 WPC) handled them quite well. So do my HK 3480 and Outlaw RR 2150 receivers.

Exactly. The poster didn't ask if it was the "ultimate" setup, he asked if it would work well. As dkg pointed out, small to med room and moderate volumes, you'll be fine--later down the road if you feel the need, you can get an external power amp.
