I have no experience with Lyra carts, but I have had great results with the LOMC carts I have run on it. I have used the ZYX 4D and Premium Mono cart and both were superb. The phono has a lot of loading options that make it mighty flexible. You could even make your own loading plugs if you want something custom or not included. I have also found folks who can make them for you if you are not DIY inclIned.
As for the sound, the kW had a great heft and weight to it. Due to the massive power supply I assume. Great foundation to the music. I loved my Avid Pulsus (which was a big step up from the SimAudio 5.3LP with optional external power supply). But the kW was a clear improvement. Most noticeable in bass, but also in treble detail.
Hope this helps. Lemme know if you have any other questions.
