I have been using the LSA Warp 1 Class D in my system since last September. The Warp 1 also uses the Texas Instruments TPA3255 “Purepath” Class D circuit. I replaced my second Willsenton R8 with the LSA Warp 1. I was using the Warp 1 to drive a completely refurbished Audible Illusions Modulus 3 A pre-amp into my Tekton Lore Be speakers. That sounded very good to my ears. I recently purchased the Eversolo DMP-A8 pre-amp streamer and for curiosity's sake, removed my Modulus pre from the chain. I moved to balanced interconnects between the DMP-A8 and the Warp 1. WOW...This combination is so quiet. It improved the definition, soundstage, and instrument position in the music without being harsh or fatiguing. I like it better than with the Audible Illusions tubes in my system. I now know the DMP-A8 has a true analog circuit for my vintage Pioneer 707 turntable. I don't have much to compare it too, but it is truly a step up from the AI Modulus I was using. I am totally impressed with the LSA Warp 1 / Eversolo DMP-A8 combination. Here is a link which describes the Warp 1 circuitry in detail. Of course, your milage my vary.
