I have a goldring 1012x mm cart which has an output of 6.5mv at 5seconds which is really high. Which of the low gain versions would be more appropriate? Given the really high output of my cartridge would the 38db schematic be appropriate or could I lower the gain event further?

At the moment I use the integrated phono stage of my rega brio r amp, but I rarely pass the 10 o'clock in the volume as the overall gain is too high.

I've seen that one, however the 38 db one seems to have better CSS for the input transistors.

I don't have one. I would try to get some around here if possible already matched, if not I'll buy a few dozens for matching.

That's a rather special category, make this one that will fit better. Your Brio R has 40dB, thus 6dB less will fare better on the volume knob.

Thanks!

My tt is a rega p5 with the rb700 arm so I feel the phono stage is the bottleneck ATM.

Already sent a PM to spencer about the jfets!
