Got me a pair of AR90's. They are quite lovely!
Paired with a Rega p2 a cambridge phono stage, NAD 3140 (love) , and an emotiva xpa-2 490 Watts per channel into 4 ohms. Listening to meddle by pink floyd right now. The clarity is UNREAL! The people at Acoustic Research were absolutely geniuses!!!

Neighbor had these in his home office since 1986. He gave them to me for my home office.
I have the 3140 and it gets hot as hell. You will need some airflow. Also a recap, probably. Had mine done recently, caps were leaky af

NAD 3140 Stereo Amplifier
Okay, what we have here is a nice nad, 3140 stereo amplifier this. These amps were built in the mid 90s and actually has some really cool features, including this speaker, EQ, which is actually a bass, enhancer and - and it's got soft clipping - and this thing called SLC, which is speaker, lead compensation. The pots were all clean here, so they are really quiet, except for this one, where it has a little bit of speaker pop because it is a switch

Looking for an amplifier to pair with Magnepan LRS and a powered subwoofer.
Used Bryston amps are a great value and a 3B or 4B tend to do some work for magnepans. If you're looking for cheaper I've heard good things about the NAD 3140 and I would assume the 3155 would work similarly.

NAD 3140 AMPLIFIER OVERVEIW AND TEST
If that distortion comes back, I won't look into that because I thought was done. While that distortion was there, it could even be now don't think it was the track, but it could have been. I don't think he was, but I will check and to turn it off and turn it back on and just before it goes being on long enough. Now it's been on a lot longer.

* Going to a cobbler to stretch them. But I've read mixed things about this procedure, so not sure it's worth it. * Buying a used pair of 3140 in a ½ size bigger, resole them and sell my current pair. Please note that these upper leather have broken in plenty and I've had these boots for years.
