Default test

Not being selfish, I thought, I could offer you, guys, a glimpse on the difference (or the lack of it?) between my two phono stages? Here is some excerpts recorded especialy for you. (109MB)

http://wtrns.fr/16Lz7Qc4o_QeGM

I would love to read your opinions. My own is: "it could be better". Duh!
You can also try and guess which is which stage, if possible.

It was recorded swapping stages and polarities on the cartridge, via not yet boxed dcb1 to my old mac which doesn't have a battery anymore, so I had to use noisy PSU. A bit crappy, but still good enough to carry out a judgement?

There is indeed a difference between the 2 versions. But most qualities out of the 2 examples are lost in conversion ... you know standard 44,1 isn't up to par with originals.
Plus, it depends which conversion card you use, external maybe ?

For me both records play fine ... TT is the Planar 3 I guess, don't remember which cartridge you have mounted on.

I would perhaps slightly prefer the 2nd versions of the test samples (assuming it is still always same phono stage order), seems to have a more direct and natural sound. I would find also the sense of space a little better. Oh well, I could be wrong after all.

You should build some other shunts to get double mono PSU on Pearl !!! It would be a tiny/but major upgrade I guess

Best,

nAr

AnaŽl, that's close to my thoughts. "Tightness" and spatial info is better on the 2nd stage. It has also a bit more gain, it seems. I've tried to level it when recording, though. Turntable is Planar 3 with a RB300 modded arm. My cartridge is Goldring 1012GX.

Double mono PSU of course would be an upgrade. Not sure if major, though. I can only guess, I would be better off with upgrading TT and cartridge. Planar 3 has a lousy coupling between motor and plinth. I would love to dismount the motor off the plinth onto some solid base and add a Geddon PSU to it. A cartridge change would benefit too. My current one was bought used on ebay. Some german gentleman sworn he used it less than 100h correctly mounted. As it was my first cartridge, I can't really judge.

As a second option, I think of ditching Rega and switching to something more decent. But that's a different $$$ story.

Back to PEARL II, I'm thinking weather some more precise R matching, different caps or getting closer voltage values to Wayne's would benefit? In other words, is there's anything left to tune? Or perhaps it's too silly, as my current rig wouldn't be able to carry out the differences.
