Re: A "Dummy" Cart For Phono Preamp Noise Testing
When I originally built the PTS I tried de clicking flat vs RIAA. It didn’t seem worth the trouble to me. Using RX. I don’t deal with pre RIAA curves. That miniDSP stuff is great. I have an MCH Streamer I want to use to pass native DSD for a cutting rig. A full blown Pyramix isn’t in the cards becau...

Re: A "Dummy" Cart For Phono Preamp Noise Testing
I’ve never been interested in that part of it. I’m still not. It seems like a lot of hoops to jump through for little benefit. I’ve never had a problem with declicking after RIAA.

Re: A "Dummy" Cart For Phono Preamp Noise Testing
I bought the Cosmos DAC. The driver software was pretty wonky. It was a while ago but you couldn’t set it up and have it keep settings. The setting it defaults to were useless. It got put on a shelf. If anyone wants it a nominal fee plus shipping and it’s yours.

Re: A "Dummy" Cart For Phono Preamp Noise Testing
Makes sense, I believe it is a bit of hair splitting, but, I guess I would have to listen to the difference between raw-processed and with RIAA. I’ve always done declicking to the RIAA de emphasized signal. Processing audio without being able to hear the result until two steps later is a bad idea i...

Re: Phono Transfer System Construction Information
i guess termination is the wrong word. Wouldn’t it alter the source impedance the opamp sees? Best to avoid that.mediatechnology wrote: ↑Fri Dec 08, 2023 7:37 pm They don't terminate it though because R4 and R5 are in series with a high impedance op amp input.

Re: Phono Transfer System Construction Information
I guess if I use the MM preamp as an MC preamp with a transformer in front of it I should use 0 ohm so it doesn’t contribute to the termination resistance. I think that’s what I did last time for the DL103 MC pre. I should open that up and take another look.

MM Preamp R4 & R5
Wayne,
I went through the threads but couldn't find or missed an explanation of the function of R4 and R5 in the flat MM Phono Preamp. It says the value can be 0Ω -499Ω. Could you explain what the function of these resistors is and how to pick a value? I think I knew this at one time but forgot.

Re: The Waveulator: Two VCA-based Clipper Saturators
I hadn’t been paying attention to this because I thought it was a distortion box, which is not high on the list. The limiter function is very interesting to me though. I might need one of these.

Re: Transfer Filter / Neumann HT75 Replacement
This was an excellent addition. I immediately put everything to use. The Widener sounds excellent. I even did two knob clicks on a track.
