Recommend Me Some Speakers

Take a look at Ascend Acoustics. Just search on the Web. They're dedicated to higher end sound on a budget. I owned a pair prior to moving up to better gear; and still use one for center channel in HT set-up. Definitely worth a listen ... they offer no-hassle in-home audition.

I'd go with QUAD 12L used. Wery nice for its price.

Magnepan MMG's. These will give you a taste of high end sound, and a healthy taste at that. They will add a degree of life and vitality often missing in box speakers - for a peanuts price.

Vandersteen 1C works very well with those Rotels, a good match and excellent value for fairly full-range speakers.

Avoid the Magnepans at all costs. They require too much placement variation and are picky about what drives them. They also have a small "sweet area" and can sound like a transistor radio if you are walking around the the room. Maggies are for people with dedicated listening rooms and the ability to try different amps. Sounds like you just want to hear good music.

Epos and PSB make good models you can find used in your price range. The Dynaudio Focus 110 is also a great speaker at about $800.00 used. Quite good looking, too.
