I used to use an ARC LS-2 (& an ARC PH-3 phono preamp) with my old Levinson NO. 27, and for a short while until I upgrade to an Ayre K-1X. It was very musical, and sounded great.
My reasons for upgrading to the Ayre, you ask?
I tired of the tube rushing, especially in the PH-3, and really wanted a deeper, darker background, especially for my turntable. The Ayre came up used locally, so I jumped on it.
PS You have good taste in amps! I like the sound of the Levinson amps so much, that when I needed more power, I just sold the No. 27, and went to the No. 23 (200 wpc).
Good Luck!
