Recently heard a Lyra Delos and a Skala into two different phonostages, one was a 47 Labs phonocube and the other was a Shindo Masseto in-built phonostage. The Shindo uses a custom Lundahl SUT inside while the 47 Labs is a clean active phono. I cannot say one had an advantage over the other, though the Shindo clearly had the edge when it came cartridge matching, especially low output impedance cartridges. The TR "desperately" needs a SUT though. Dont try to use the TR direct into the active phono, it is a very very tough route to go that way. Rather a nice Lundahl SUT into your ARC MM phonostage will be a simple and direct way to get very high performance out of the TR.
Anyway I prefer the Lyra to the TR :-).
