Not sure what I am going to do with the preamp. I just had it upgraded, it sounds good, and I really wanted to like it better than my Lamm LL2 Deluxe, but after recently reinstalling the Lamm, I believe the MUSE is just not as good sonically. Maybe the MUSE is a little tighter and more dynamic in the bass, and perhaps better overall for rock music, with more gain, but otherwise the Lamm just plain sounds better to me. Too bad, because the features and operation of the MUSE preamp are hard to beat with the adjustable gain, 0.5 dB volume steps that are displayed as actual attenuation and gain values (which I like better than any volume control I have used), and remote control of phase, mute, input, volume, balance, skip and direct track. It has HT pass through and is also fully balanced, which works better for me with my balanced Clayton monoblocks. From a feature standpoint alone, I have never used a better preamp. I will probably put it back in my system in a week or so and see if I miss the Lamm.
