How much difference does a phono stage make?

Thanks guys for your feedback. Would I have to change a resistor inside to give me the correct gain for my Micro 2.5mv? What gain would I need, or is this something you have to just try out and experiment with?

The PH3 has a FIXED gain of 54db, you can't change it. You can change both input impedance and input capacitance by changing the resistor and capacitor inside.

Your cartridge at 2.5mv, will work fine with the 54db of gain of the PH3.

Everything above makes good sense. What does your Scout sit on? When I had my Scout I definitely noticed performance differences depending upon the table/stand. I like the 4" solid maple platforms from MapleShade.

Interesting thread.

Phono amps are a bit of a mystery tp me. But I found Dougdeacon post very helpfull. Now I'm using me intergrated amplifiers phono stage. But sometimes I wonder wether it would be a good idea to buy a seperate phono amp. However with my current financial state a nice phono amp is out of the question.

I'm slowly clawing my way back into Vinyl LP's after 30 years having received a well preserved collection of albums from an estate sale. Now my collection is about six or seven feet wide (most discs are in pristine condition).

My original "plan" was to transcribe the Vinyl LP's (via PC) to CompactDisc's through an external Edirol/Roland USB soundcard at high sample rates for "archiving" onto hard drives and possible audio CD creation. I did some research and bought a Bellari VP130 phono amp which I tube rolled with a Tesla 12AX7 TE-ECC803S and hooked everything together using a five year old Gemini SA6000 "DJ" turntable (yikes!) with a Boston Audio Mat1 and a record weight with the carefully protractor aligned and balanced stock Audio Technica AT92E cart.

I plugged a set of (exremely modest)Sony MDR-V6 cans into the little Bellari phono stage and was actually quite impressed at the sound of several of the cleaner LP's that I dusted off with a moistened 25 year old Parastatik "Disc Preener" (a foam backed velvet cleaner tool).

I sat about thinking that dumping the output of good vinyl through a mediocre turntable into a computer that is only designed to create a 44.1Khz digital reproduction of audio that's being "cut off at the knees" by the very technology that lead mankind away from superior analogue, I figured I was quickly headed down the wrong path.

In a few weeks I bought a contemprary European belt drive turn table (not Thorens) with all the design upgrades to minimize vibration issues and a decent cartridge. The next logical step in my mind would be a tube integrated amp to replace the Sony home theatre receiver, though this brings me to the next question: will I experience a dramatic improvement in the subjective characteristics of the sound of vinyl LP playback if I replace the Bellari phono stage with another "high-end" phono stage?

I've already actually experienced the benefit of hearing a big improvement in the sound of vinyl LP playback by using the Bellari phono stage through my amp's "aux" input(instead of simply using my Sony solid state receiver's "phono" input connection), the graphite turntable mat and the record weight. But I guess I'm asking where the "cieling" is in the quest for better audio as it relates to improving the output of the MM cartridge by using a phono stage with perhaps more capability than the Bellari VP130 model?

Thanx in advance. (audio neophyte)
