looking to go from seperates to intergrated

Although it is not a compact physical package, the Aronov LS-960I is an easy recommendation. I have played it through everything from mini-monitor Spendor LS3/5A's up through big floorstanding Clements RT-7's (transmission line bass, ribbon tweeter), with pleasure.
From a listening perspective, it is an "improvement" over most other realistically priced integrated amps, and also a "bargain" at a used price in the $1500 range.
Newbee is certainly correct that there is no universal unit, but the Aronov is at home with a variety of source, loudspeaker, and room choices. It is a unit sounding so fine that one does not feel restless to replace it.

A Jadis Orchestra Reference has just been put up for sale (not related to me) for $1950 asking price. It sure looks great as much as a virtual component can impress in an ad.
Since my Aronov recommendation would also be a great match, but is not for sale used today, that Jadis sure looks comparable, at a higher "bargain" price for an esoteric piece.
