Also, for the people who are interested, I noticed that the amp boards that I received did not have the Maron 560uF caps as shown on the picture on the ClassD site. A lot of people on the audiocircle board had commented on the lower quality of these caps in respect to the rest of the amp. Tom must have listened because they are now Panasonic 680uF caps. So again, I see a lot of high quality parts on these boards.

I just read through the manually and see how they are setup if you want to build external off/on switch as well as extending the leds. A little soldering possibly, but nothing to crazy. Man if this works out Steve and your happy with the performance and sound of D technology, I may have to consider this some day. Thanks for bringing this to our attention. Sure beats the heck out of the cost of other mfg'd amps with the same power. Are you going to build a mono version for the VP180 if all works out?

I'm hoping it sounds at least as good (but with more power) as the amp stage on the AVR-3806. I know, high hopes... But, if it works out that way I was considering a mono version for the VP180 in the short term, and in the long term buying exaclty what I bought again but wiring it unbridged to power the four surrond/rear channels. At that point, I would sell my AVR-3806 and buy a preamp/processor instead (something similar to the Emotiva UMC-1).

What, I'm the only one who needs scale? Great, Steve. I appreciate the pictures and writeup.

Looking very good. As I mentioned if this works out, there will be a number of sales from this build. Now just to decide on a chassis to put this into. Anyone found anything online. I could build a wood enclosure like others have done but I would like the manufactured look(steel/plastic/aluminum) to match the rest of the system

A guy named Jason (jtwrace) on the audiocircle board makes a case for this with everything pre-drilled and labeled. His gallery is here: http://www.audiocircle.com/index.php?action=gallery;sa=album;id=4288 I have not contacted him yet, so I don't know the cost or if they are still available. I'm not sure if I'm going to build a case myself or go with something like that. You can however find some places online that have plain old aluminum or steel cases if you choose to drill yourself: http://www.par-metal.com/I'm hoping that the amp sounds great and he does get a lot of business becuase he seems like a nice guy who makes a nice product (I always like to see good quality parts being used). I know on the audiocircle site he gave that group a 5% discount. So, if after I put it together and it sounds good, I'll let him know about this board and see if he wants to offer a board discount to us.

I could build a wood enclosure like others have done but I would like the manufactured look(steel/plastic/aluminum) to match the rest of the system Here are a couple of sites for enclosures-- Hammond, and Mouser and Lansing. Also, here's a place that can custom cut and punch a front panel.

This site looks interesting. You can fully design your own case and they can build it for you. I have no idea of the cost, but it looks pretty neat for those that don't have the means/knowledge for making his or her own.

Steve, that kit looks very cool. I'm eagerly awaiting your impressions. I like the fact that all the dirty work is kinda done already. I am certainly a novice when it comes to soldering and this seems like a good first project.
