Hi James, Yamaha CX-1 seems to be last piece of all Bratwurst´s Yammies now. Remeber AX-1090, CX + MX, C+M, AX-500 maybe A-720 or A-1020. How different is 250W/8Ohm Denon monoblock now? :)

Thank You for many posts, threads, pictures, tips and tricks...My favorite late-night TV program :)
Jakub

I hope that next episode satpaul CX-2 recap with refurb list will follow...:)

Thanks James for the support. It's playing better and better. I expect it to be even better after 2 weeks. It's so smooth and clean and the dynamics are beautiful. Pavel.:banana:

I really really love planar tweeters. I think that you probably do too! :biggrin:

Hi Jakub, The Denon monoblocks are amazing. The MX-1 made me very happy, and if Yamaha had made a 250W monoblock I would have bought them, but the imaging with the POA 6600's is simply wonderful.

I am very happy with the modded CD-S2000 too!

Thank you for your kind comments.

I think that the AX-750 is a very integrated nice amp. Better than the AX-890 that I am working on right now.

Yes, they are amazing machines. But they are not mine. They are friends' for repair and maintenance. The AX-750 is a very well designed integrated amplifier. Pavel;)
 
And as for Denon. I also like it very much. I worked on the PMA-920, very beautiful design, Pavel


Denon PMA-920

I got the PMA-920 for free. The box was in great condition. But the right and left channels were completely burnt out, the transformer was burnt out in the primary. And besides, someone tried to fix it. Crazy, he put whatever he had in the drawer in the driver. Some plagiarisms in the output...

There are my experience with sound, A-700, A-720, AX-700, AX-730, AX-750, (AX-870 slightly better than 890) very good mid class, AX-890, AX-892 good in mid class...:) My CX-2 is now in mint condition, but Pavel challenge with recap is awaited...:)
 
They are finishing the M-65 now, I'm just waiting for the terminal from Speaker terminals. And there's also the C-65, it will take even more work, but it will be a beautiful assembly when I finish it. I'll post it here too when it's done.Pavel ;)
 
I bought terminals from Speaker Terminals for my Denon amps. They do very good work. The terminals were well made and a drop in fit. I think that you will like them.

They are nicely made. I've just been waiting a long time. I ordered it on March 10th and I still haven't received anything, so I wrote an email today asking where it is and they said they have to produce it, that there is a lot of interest, so they will send it either tomorrow or Saturday.Pavel ;)
 
So here is the CX-2. First I took it all apart. Look at the marked capacitors (in red) in the signal path.

And then slowly put everything back together, the cables from the MC Head Amp get tangled.
