How much difference does a phono preamp really make?


Sorry for the noob question...

I have a Technics SL1200-GR turntable with two cartridges; a Denon DL110 and a Clearaudio Performer. I also have two phono stages; a Consonance PM6 and the internal phono stage in my Belles Aria integrated. 

To my ears, there is no discernable difference in sound between the two phono stages. 

I'm just wondering, if I went up to say a Clearaudio Smart Phono, or a Rogue, or even a GoldNote PH-10; would I be able to tell? How critical is a quality phono pre in analog sound reproduction?

Thanks,
Joe

Not only are those 2 very basic phono stages, probably with the same kind of chip based circuitry, but a 40dB MM stage (like the Consonance, and probably your Aria built-in) is going to be way underpowered for your Denon’s 1.6mV (this results in 0.16 V when a typical CD player outputs 2.0 V, a full 22 dB above the former), whereas a 60dB MC stage is going a bit too much for it (risking overload).

And though it’s an entry-level MC, which won’t garner too many fans here on audiogon for its plastic body alone, you are probably far from hearing that Denon 110 at optimal. The 110 is kind of an odd-man out for most phono stages, which typically cater either to higher output MMs or lower output MCs, and (importantly) often don’t offer 47K loading (recommended for your Denon) in MC mode. What you want, optimally, is low 50s dB gain at 47K.

Get a Hagerman Trumpet MC ($1100) and you will hear a difference! It can do 45, 55, 60, 64, or 68 dB. All loading settings available at all gains, including 47K.
Only your hairdresser knows for sure.
It is quite critical but your system, room or ears might not be up to the task. There IS only one way to find out, try it.
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…
