Would I be wasting my money to get a turntable?

Unless you just want to play with a turntable, the answer is yes, you’d be wasting your money. Sound quality is no better and on most recordings, it worse.

There’s no amount of money one can spend to make a poorly recorded album sound like a great one.

@OP If you don't already have a large record collection the answer is absolutely not. It's not just a question of whether the TT will be as good as your existing streaming system but also the opportunity coast. For what you will spend on the analogue playback you can make a substantial upgrade to your existing system.

This spanned the widths and depths of logic and reasoning ranging from the metaphysical to the ultra-technical.  He he...I'd say it's really just a matter of two things:  Do you want to?  Can you afford it?  Do it.  Even small budgets can get into a system that will reveal whether or not you'd be into it going forward.  And we love to upgrade so if it sticks you can do that later.  If it doesn't work out, sell it.  The net would be worth it, I think, to have tried it.

The overwhelming majority of you guys aren’t answering his question. He’s not simply asking is adding a vinyl rig worth his time and money.

He’s asking, since he has an amp that digitizes analog signals (you know like turntables) would that negate the point of having a vinyl rig.

carsbad yes it has an analog input which is them digitized so analog goes through an a to d conversion process no ANALOG PASS THROUGH ON THE M33
