Vinyl and Lyngdorf TDAI-3400?

That's what I imagined, is impossible the digitalization of phono signal do not affect the sound characteristics of vinyl... in a not so pleasant way...

I presume that the same applies when using DSP, and room correction? 

Someone can solve a doubt of mine about the Lyngdorf room perfect feature?

this feature only works with speakers with separated sub woofers? or it functions as well with 3 way loudspeakers with a 12" woofer driver for example?

Thanks!
