Need Advise for open sounding monitors

GoldenEar Aon 3 ($1K/pair retail). It employs a modern folded ribbon based on the Heil concept. Upper mids and treble are very clean yet relaxed with no edginess. Yet treble is very extended and like the old Heils, they're very fast. The built-in oval passive radiator helps get bigger yet tighter bass out of a relatively small package.

The Usher BE 718's are hard to beat at the price.

OHM Walsh speakers have a lot of monitor-like sonic attributes except they are full range floor standers with a small footprint that do not require separate stands. The omni-directional design is inherently open sounding. Cost is more than competitive with many top rated monitors. The main consideration for chosing a model is room size. The models from just over $1000 to over $6000 all tend to sound the same when properly matched to room size and acoustics.

Otherwise, the monitors that I have heard and like best are various Dynaudios and the Totem Mani 2. PSB synchrony is another monitor worth consideration.

ANy of these would match well to the Mac electronics in general, I would expect. I have heard the Totems specifically with large Mac SS amplification and they were very impressive.

Totem Mani-2. They will work well with your 350/wpc and give you the bass response you're used to. I don't think there's any way you can go from 15" woofers to a small monitor and be satisfied, but the Mani's will likely fill the bill for you. Make sure to buy some very solid stands.

I have a pair of Decware DM945 monitors (8" full range woofer, Ribon tweeter) that sound very transparent and have good bass in my 12x18 ft. room. They only have one capacitor for a crossover. Worth checking into...
