NAD 3140 - I know nothing

Wetagogo,

The post from above, "You should release the Bridging button when using with 2 speakers." is not correct. The bridging button is for bridging two amplifiers. In that case, you reset the jumpers with patch cords to the second amp, and run speaker wires from the positive terminals. I had that setup with my 3140 and 2150. Don't do it until you know more! You can damage your system.

SLC is for "speaker lead compensator," which NAD devised for longer speaker runs. I am not sure how it corrects, or if it is even useful. Best to use shorter wire runs (less than 10 feet) if feasible.

What you need is the owner's manual. If you cannot get it on line through NAD, e-mail me and I will fax you a copy. I believe I still have mine. However, we just moved and it will be next week at the earliest until I can find it and fax it, but if you are interested let me know.

Sorry for the error - I thought bridging was for using it in mono like some amps to get more power - listen to Tim, he has the particulat unit so he sounds like he knows for sure.

Gonglee, maybe a misunderstanding on my part of what you were saying. It sounds like we are saying the same thing. The bridging button is for running one speaker per amp, but you need a matching amp to do it. NAD actually made a power only amp to match the integrated 3140 for this purpose. I believe it was the 2140 (40 wpc, and also bridgable). When I was ready to upgrade (many years ago) that amp was no longer made and the dealer said the newer 2150 would also work. Apparently, NAD was so conservative in power rating their earlier amps, they kept essentially the same design and simply increased the power rating, so I was told. Anyway, my 3140/2150 combination served me well for many years and both amps are still in use in my second and third systems. Consulting the owner's manual should clear up the purpose and use of all the buttons for him, and my offer is good to get him a copy if he needs it, since I still have mine. - Tim

I like nad amps/ integrateds for what they are: solid performers for the money. Like Quadophile, I owned a NAD 3255PE and I really wish I still had it. It was a punchy little 25watt-er which mated really nicely with my Energy ESM4's at the time.

You know, I never really appreciated that equipment THEN as much as I do NOW (even though i don't own the equipment anymore)... it's just that over the years, I realize that equipment was quite competitive even with some of the mid-fi stuff available today.

Hi all - I've bought some speakers which really appeal to me and, I believe, let me hear what the 3140 can do.

I went to one of the few shops here in Auckland, New Zealand, which sell used gear. I took the 3140 and my (cheap, old) Sony CDP-XE500 CD player and some favorite CDs, and listened to about a dozen pairs of bookshelf (and a bit bigger) speakers.

The ones I bought really stood out against the new and used Mission, Audio Research, Klipsch, Morduant Short and others I listened to. They even sounded better than some much more expensive models.

These JBL HLS610 bookshelf speakers sounded so smooth, full, expressive, warm, clear, clean, detailed, and airy when compared to the others I just had to have them.

When I got home I searched the net for reviews and found a very enthusiastic one by Cory Greenburg of "Audio" magazine which, among other things, said "as soon as the HLS610s started singing, I knew that they were special. They had that immediatly recognizable rightness to their sound that seems to elude all but a very few audio designers" and "The sheer amount of recorded detail I heard from the HLS610s was a revelation".
