Finishing work.




Test: Everything works.

A little longer...


It was done: Replacing all elites. Replacing all OPs with OPA1642 in the lines. For MC Head 1/2 OPA1656 2/2 OPA1642. I strongly recommend cleaning all switches! The entanglement of signal wires brought better spacing on MC and MM and CD. And a complete cleaning. I don't know if I forgot something if you ask. It plays incredibly well, I recommend this upgrade. DONE.

Looks like the original super capacitor as well 4.7millifarad @5.5vdc.

 

[satpaul]

Yes, I left the original one too, it measured fine. Greetings avionic.

I've been playing for about 20 days and it's smoother, cleaner, more spacious. Wonderful!!!

Very nice work Pavel, looks beautiful!

This is the first time that I have seen photos of the insides of a CX-2 so your thread is very interesting to me. Also, nice work cutting the M3 threads in the MX-1 heat sinks.

Now I listened to Metallica Black Album just for a test. Because I adjusted the MC preamp input on my MC-9. When measuring the MC l+p channel it was 28.7 Ohm so I adjusted the input impedance on the MC preamp input to 270 Ohm. And bingo what an improvement!!! I read here on AK that 10x the resistance on the input impedance of the MC preamp is ideal. I guess so, it plays 100% better.

It sings here with my NS1000M, one of the most understated amps made by Yamaha, the HCA circuit gives clean dynamic power without any drama.

Yamaha Control amplifier chassis. With those damn plastic side panels. C-60/65 or C-80/85.

 

[satpaul]

That's right, C-65 is on the table right now.

Nice pair with top cover screws...

So after 20 days of playing CX-2,MX-1:
At first I found only minor differences in listening, but yesterday there was a turning point in the ignition of the new components and a huge leap in sound!!! Now it sounds incredible. Words cannot describe it, just two to three classes higher!!! Amazing, amazing sound presentation. It expanded into the width, depth of the image. Treble, midrange, bass... incredibly sweet...
