What is interesting in your simulation is that the Masterpiece is superior to the Paradise in the bass.

what you are saying makes total sense.
Higher degeneration a little higher noise but lower distortion and better DC performance.
Paralleling devices in my listening expeerience didn't yeald to a good result but I am willing to re-evaluate that and re-try.

Anyway, if simulator hasn't smoked anything and if this results are REAL, this is a whooppie low noise result.
If this simulation is accurate this would be the quitest phono stage in the entire history of phonos !!!!


I rearranged the RIAA and below is noise performance and re-arranged RIAA.


What do you think?

yep and I can confirm you that the bass response is as clen as it gets.
Almost remind you of a CD player in a good sense.
Something I have never had with other phonos I have built and tried so far.

And if you think that it was better in bass area, just look at the new graph

and last...this is Christmas....free million dollar gift to everybody!!!

My personal Masterpiece for you, standard values, absolute precision, epic bass response and ultra low noise.
Re-arranged RIAA with relative frequenqy response.

This is now, in theory so far, a breakthrough design didn't take a squat team nor 3 years like paradise to come alive ahahahahahah!!! Hopefully bench results will confirm these fantastic data.

I hope it is real.
Anyway, i believe in miracles, small ones.

and this is a big one!!!! ahahahaha
For one thing the resistors on the RIAA have lowered which took big part of the noise down.
Plus splitting the cap apparantly took another big chunk of the noise out (no explanation for this).

Anyhow, I have ordered V-Caps CuTFT just a little bit ago and this weekend I will be conducting tests on the latest topology.
This might be the end of it in terms of phono design.

One gain, fully balance, high precision, low noise, low distortion and most of all amazing sound.

Just aside, I don't believe in miracle at all, so to me it seems almost impossible, but I am giving it a try anyway!!

Just a little update: I figured out where the distortion was coming from and fixed it.
One of the active device on my line stage must had blown up for some strange reason.
Tomorrow maybe I will start working on the updates and test them.

Stay tuned.v

Does reducing the riaa resistors and upping the caps also cause a higher amplification factor in this design ?

Can some of the findings here be tranposed to the original paradise ?
