Onhwy61, I've got a great vinyl setup and plenty of good D2D recordings and hi rez vinyl, but I think that DVD-A and SACD is as good, when well done.
Pedrillo,
Maybe I misunderstood your proposed use of the Korg. If you mean that you'd record a great D2D recording and then carry the Korg around to various stores to use as a source to compare different speakers in different stores, then yes, I's fantastic for that. I recorded some great big band, organ and other high dynamic recording and took it to a dealer to hear the Vienna Acoustic Mahler speakers flap my pants leg to great effect.
My dealer had a great TT, but you didn't have to worry about that with the Korg. You simply plug it into a line pre-amp and push Play.
I thought you were talking about recording speakers. I don't think that'd work because of the difficulties of recording different speakers in different venues.
You'll be able to use LPs that you're very familiar with. OTOH, you might get a few really good SACDs (Chesky has several and then familiarize yourself at home. An Oppo universal SACD is only 20% the cost of the Kore). Any good dealer will be able to play SACD.
