Brute power cheap?? Adcom Vs. Rotel vs. NAD

They may not have the SNOB appeal, but the newer Adcom gear is truly outstanding.

My good friend is using an Adcom 5802 to drive his Martin Logan CLSs. The sound is breathtaking. Smooth and powerful with plenty of finesse. Even at the new price of $1800, it's quite a deal. But used for ~$900 - it's an outright steal!

You'd have to spend a WHOLE lot more to do appreciably better. You've summarized it quite well with regard to the NAD products. They're very thick sounding. I think the MOSFETs of the Adcom coupled with the ribbon tweeter on the Maggies would sound terrific. The next best thing to a high-powered tube amp with the Magnepans is a nice MOSFET amp to smooth things out.

Others will recommend the usual suspects; Bryston, Aragon, etc. I wonder how many have actually listened - objectively - to the Adcom. Don't get caught up in the brand hype.

(BTW - I DO NOT own any Adcom gear, so there's not hidden agenda.)

Good luck to you!

Hafler is another good choice. It, too, is a MOSFET design. I used to own an Acoustat TransNova Twin 200 which, I believe, was made by Hafler and was designed, obviously, for use with the Acoustat speakers.

Great recommendation.

Chazzbo,

I've owned both NAD (still do) and Rotel. When deciding on an upgrade several years ago, I auditioned NAD, Rotel, B&K, Hafler, and Adcom. I preferred them in this order: Rotel (bought), NAD (2400 a close 2nd, great bass, but the Rotel's highs were better), Hafler (Transnova) and then a tie at the bottom between Adcom and B&K. I don't remember what I didn't like about the B&K or the model I listened to. I do remember thinking that the Adcom sounded lifeless to me, but I don't remember what model it was.

I have a set of smaller Maggies in a second system that I replaced amplification for about a year ago. I did mucho auditioning and will give you my impressions.

1) Rotel 1080 was precluded because it doesn't like low impedance loads.
2) Adcom amps struck me as having a bright top end, not to my liking.
3) NAD 218 has a solid bottom end, but not as much detail in the high frequencies.
4) Parasound HCA 1500A has great mids and smooth and detailed top end, but a little soft in the bottom registers.
5) I've not auditioned the Hafler 9505, but the amp I replaced was a 20 year old DH200 still in fine working order. I do like the Hafler sound.

I chose the Parasound and have been pleased with it.

P.S. Regarding bridging, I ruled it out as bridged amps don't do well into low impedance loads and bass can get sloppy. I would consider two amps in vertical biamp over bridged mode. Two NAD 218's or Parasound 1500A's can be had used in the neighborhood of $1,000 total.

Why you need 900 watts with Maggies?? Get a used Muse 160 and matching 3 pre used for about 1600. This combo will be musical and far better than anything you mentioned.Fully balanced 160 per.
