A closer view of the MSR.... (Mighty Salas Riaa)

There is a lot less compression, the instruments are more individualized, soundstage is good and there is a lot more detail.

I hear previously hidden parts of the recordings with great detail.

Highs (guitar chords, metal platters in the drums) are now becoming very strong and detailed (lifelike).

All this after 1/2 hour playing.

good work !

now tray to bypass the pre ,you need a decent pot ...alps suck, at low level there is 3-6db tracking error beetwin channel and some THD for delicate mechanical contact

order the cheap optivol from ska-amp ,change the two series resistor with tantalium ,a lot better then normal pot

PS
I will came back with my shunt ,after solved my family problem....

Do you mean I can use only a pot between the Riaa and the power amp ?

Ricardo-

I run straight in. Still don't have a volume control- so listening is limited to daytime. I believe you have the output buffer so it should work well straight into an amp.

I intend to build one of those ldr attenuators (lightspeed thread); I might need to buffer it's output... Straight in, mine is about as loud as I need. But YMMV...

Means a John Curl buffer. But your RIAA is already buffered so it will not lose from its own gain. And a further buffer after the pot will not add gain either. It may interface the pot nicer, but that is all. The main thing is if you get enough drive for your habits to the main amps, speaker, room, system.
