On a slightly different point, I don't think I have heard or experienced a really high end Vinyl Rig so far.
I can only comment on what I hear from what I have on my Rig and Yes, at times I really like what I hear but I don't have another rig to compare it to.
As pointed out, my Mofi deck with my Cartridge is probably only giving me a taste of what is possible but right now, I don't think I can really up the ante.
I just purchased a lightly used Phono Stage - Lab12 Melto 1 and I feel that has brought up the level a little bit (in my other thread I discussed how I unfortunately damaged my Sim Audio Moon 110lp v2 phono, which hopefully I will be getting repaired) and so I had to get another Phono Pre-Amp.
Going to shows I get to listen to other rigs but are they really setup that great? Probably not.
I only really get to go to one really, being in Socal, The SHOW in Costa Mesa.
So, it's difficult to gauge anything there.
I supposed I could ask a dealer to set something up but I don't want to bother if I am not actually going to purchase anything.
