[HD-5000]

I just replaced the op-amps in my Denon DCM-370 with a pair of BB2134's, but because of the peculiar layout of the inside, it is as difficult as sin to get to anything. In case you might want to do this to yours, let me show you some tips, but do this at your own risk!

Notice how the board is mounted upside down? Don't worry, there is no need to do any desoldering anything but the original chips themselves. First, plug in the unit and make the tray slide out, then turn off the power. Now, you should have about 3 inches to work with. Locate the 2 chips, which are at the right side of the board, and each are located about one inch from each other. Desolder and remove those with your hand stuck under the board.

Now here's the hard part, trying to fit the Burr Browns into the vacant spots. I could not do this with my hands, so I took a pencil and hot glued the chips onto the tip. Make sure that you place it on correctly, not backwards

. Place them carefully over the vacant spot. Now, solder. That wasn't too hard, was it?

And while your at it, unplug the 3-pronged headphone power cable that is located at either the board or near the headphone plug itself.

Finally you can now replace the chassis cover.

As for the sound, I'm not going to comment in detail but I can safely say it works

and the sound now seems to have more weight as you may call it and an improved sense of detail-especially in the bass.

Nice going, HD5000!

What were the stock chips? Were they smd? Are you going to roll the chips? How about the coupling caps at the output? PS?

You are the first to mod his Denon 370, more than just disconnecting the hp. With so many 370's out there, I'm surprised no one hasn't done more to the denon 370. Probably because of poor access to the board?
