The 380S is also an exceptionally clear and transparent preamp. I wouldn't say the 320 is any kind of major improvement over the 380S, just different. Go to the Mark Levinson web site and take a look at the huge power supply in the 380S and then look at the one in the 320S and 326. If Mark Levinson makes these preamps any smaller their going to start to look like a high class desk top stereo. Buy yourself a used 380S and save a bundle.
