Frontier1,
I'm fully with Rauliruegas on this one!
Excuse this crazy question but have you tried the Lyra straight into the MM input of your Shindo? This might give you a taste of how good a non-SUT setup can be? I do not doubt that there a great SUTs out there but they are few and far between(probably expensive too, + extra interconnect cost)), I personally never came across one.
I have a 0.28mV MC Colibri which I ran for a year into the ARC Ref Phono MC input (built-in Jensen SUT, 69db gain). Not sure what alcohol or drug I was on one night but I tried it into MM (48db gain) and up to this day I can't believe how much better it is. Yes there's a bit more hiss but the sound, OMG! So I'm now looking for a higher output Colibri. For half the cost of a great SUT I suspect you can finance an upgrade/crossgrade to a good non-SUT valve higher gain phono stage, maybe. BTW it also wouldn't suprise me if a cheaper higher output Lyra sounds better straight into MM than your current cart through an SUT...
