NAD receiver 7400

NeilGabriel

I am thinking of pulling the proverbial trigger on a nad 7400 that appears to have excellent power for 4 ohm speakers. I am getting this (maybe) for a pure 2 channel old school system. Can anyone confirm this will be good choice for 4 ohms (Lsi9s)? Thanks.

No opinons on this? Thought there were some nad advocates here?

There are......but even more so for the LSI's.And every one of them will tell you to get a seperate amp for them at close to if not more than 200 watts.Not that the Nad won't drive them,but you won't get the most out of the lsi's either.Plenty of info here on this.If you don't listen all that loud,by all means,pull the trigger.

from the older NAD gear that i've owned... I have kept and still use most of it on a nearly daily basis.

You can't go wrong with NAD as far as I'm concerned.

get the NAD receiver. then if you feel you need a separate amp.. get it down the road..

I would just get a preamp and a min 200 watt 2 channel amp. Take time to find what you want. LSi's sound fully with more juice. Amps drive me crasy. "It's a 90 watts a channel amp but is high current and will sustain a 1000 watts for 1 micro second" Just get make 200 watt amp and stop playing word game. Ops Rant. LOL

Nothing like a good rant to get the blood flowing...I prefer tampatails.com.

I'm not a big separates guy (as in I just sold my pre/pro and 5 channel amp), but I could use my carver integrated as a pre and team it up with a power amp. I do like to listen louder than most old fogies....but 200 watts a channel seems like a lot for a 10x12 listening room. Thoughts again??

Small room......so grab the nad then.It's not the best idea to underpower speakers,but as long as you don't crank on that volume dial,you should be OK.Or choose a different speaker.You don't buy a race car and put regular unleaded in it,know what I mean?

As long as you have the high current ratings, the watts are nothing to be concerned with, NAD is great for providing large amounts of the needed headroom.

my Manley Stingray drives my LSI to copius levels with its 20 watts per channel.

I think Ted is making a valid comparison. I know he has owned quite a bit of NAD gear and his point is high current power whether NAD or Manley will drive the LSi series nicely even when rated as a low wpc.

"While the 7400 is conservatively rated at 100 watts per channel continuous power for test tones, its Power Envelope circuit produces upwards of 370 watts per channel of long-term dynamic power for music, with a peak current of 40 amperes for precise control of voice-coil motion with speaker impedances as low as 2 ohms. "<--from the NAD spec sheet. It does not give a continuous power rating into 4 ohms. I am keen on a receiver...then again I've lost too much money on stuff I bought to test drive.

P.S. I could ask my wife, but she would want to know if we can get it at Home Depot.

I had a Nad 7600 reciever to drive my SRS polks. It's fine at resonable volumes. The Nad has a nice lay out and is easy to use for 2 channel. The tuner is also very good. Get rabbit from RS for an antenna or best an outside antenna and you will be very surprised at the quality of FM, assuming there are good FM broadcasts in your area, like near a big city.

I sold the Nad a few years later and made my money back.

How much for the Nad 7400?

IMHO...that Manley outclasses the Nad by a large margin.But I did get his point.However,I believe the poster is going the economical route and won't find Too many low wattage,high current gear.The Nad will power them,but if you press it too much,you won't be a happy camper.Seeing that he has a small room,can't imagine him pushing the limits,so as I said,go for it.

Running Onkyo M504 amp 165 watts and 200 watts Adcom 555II. the music was fuller and warmer. Both are high current amps. Adcom wins hands down no holds barred.

Here's what I don't get. about power needs...if I have good clean high current power, and you can run 4 ohm speakers at decent volumes with 10-15 watts, why do you need 200 watts as opposed to 150? I am sure I will be dead before this sinks in. I'm gonna just run the Lsi9s with my carver for now (150 watts into 4 ohms) and see how it goes before I buy any other power sources. Thanks a lot. This was really helpful, except for the stuff that baffles me.

reeltrouble1

bingo you got it. very small difference between 150 and 200, very small very small, hear me, that is where the current comes in, how many electrons dancing down the pipe to carry those transients, especially those bass ones, then look at the slew rate, how fast is she?
