I also got a package today 😊
... and after some soldering I have these now :
These are 2 CVX2 LPTDACs, one with resistors that have 0.1% tolerance - the other with 1% tolerance all picked by dreamblaster from the same batch (so they can be as similar to each other as possible). I have installed a temporary capacitor "socket" so it is easy to test different values. It's not good for a permanent solution though...
So naturally I made some Crystal Dreams recordings:
0.1% CVX2 with 4.7nf capacitor: https://soundcloud.com/keropi666/serdaco-cvx2 … -crystal-dreams
0.1% CVX2 with 10nf capacitor: https://soundcloud.com/keropi666/serdaco-cvx2 … -crystal-dreams
1% CVX2 with 4.7nf capacitor: https://soundcloud.com/keropi666/serdaco-cvx2 … -crystal-dreams
1% CVX2 with 10nf capacitor: https://soundcloud.com/keropi666/serdaco-cvx2 … -crystal-dreams
I cannot hear a difference between the 0.1% and 1% versions with the same value capacitor - since even 1% tolerance is really good and the resistors are from the same batch I don't think it really matters what resistor tolerance one uses.
CVX2 blows away my previous covox clone - infact I'll go as far as to say that the previous clone is almost garbage compared to CVX2 🤣
Thanks so much dreamblaster for creating and sending over the CVX2! It really makes you spin your head with the sound quality it produces over the LPT port 😎
ps. anyone knows a program that allows 2x LPTDACs to be used for stereo sound?
