How much difference does a phono preamp really make?

As everyone else has said, the Phono Pre is as important as the Turntable itself because of the delicate signal it has to amplify. The hierarchy of the vinyl chain is Turntable, arm and cartridge in that order. With that said, I'm a little surprised that you can hear no differences  between the 2 carts. There should be some subtle changes. 

Did you try both settings (MM/MC) on the PM6 with the Denon?


If so did one sound better then the other?

It can make a huge difference.

I was skeptical as were my sons. Read an article in Stereophile by Fremmer and he was exuding using a MM phone pre dedicated to MM. so I bought one he recommended. My stepson could here the difference immediately. He spent his days listening to music as he was disabled after he hit by an intoxicated motorist. He came to live his mother and I.

I miss him…

@artemus_5  I can hear a difference between the two carts. Not so much with the two phono pre's

@earlflynn  I'm very sorry to hear about your stepson. Thank for your input. 

@dekay  I did. The Denon sounded better on the MC setting although I believe the manufacturer recommends using MM. 

Thank you to everyone else so far. It seems like my carts may not be good enough for me to notice a difference between my entry phono stages. 

I posted a question to the Technics SL1200 group on Facebook about recommended cartridges. Most seemed to point to the ATVM760 SLC. Would this be a significant upgrade to my Denon and Clearaudio?

Thanks!! 

It can make a huge difference.

First fundamental step is make sure phono input specs match cart output specs ie the two are compatible. Then you are baselined optimally to assess any other differences from device to device, if it still matters enough to you.

Of course its a system so everything else downstream from pre-amp to speakers to setup in the room matters as well. The trick is to figure out the weak link and focus on that as needed. Don’t get too hung up in one place.

If that sounds hard, then consider one the many integrated solutions available today and there are many very good ones capable of competing with many high quality separates. The engineers ie the technical experts have integrated the things that matter for you there. That can help take a lot of the guessing out of the game. You still need to pick a cartridge that is compatible and in many but not all cases speakers as well.
