Assembled chip amp board with high SQ

TCx · 29th April 2010, 05:48 PM

Hi, I am quite new to diy HiFi... I am looking for a great sounding assembled chip amp board - preferably with LM4780 but not necessarily. If there is no other way, I can start even with a kit and solder components myself but I prefer finished board, if possible.
I want to use it with 8 ohm floorstanders (which cost about $2000) so I need the board to be reliable - I do not want to damage the speakers by failure of a cheap amp board. So some protections (like against DC on speaker outpts etc.) are welcome on the board. But SQ is my highest priority.
I do not need much volume, I prefer low or medium volume levels.
I will appreciate your suggestions...
Thanks!

Bite the bullet and have a go at building one... Soldering is a little fiddly, but not over difficult.

The 4780 is my first and only build upto now. It was also my first ever time soldering. If I can do it... ANYONE can. If I pick up a tool, it usualy means i'm gonna break something.

As for sound quality.. Awsome.

I have used several like this, with the LM3886 IC. Although you will need a power supply, the chip amp part comes completely assembled:
Dual Mano LM3886 Mini Amplifier Finished PCB 68W X 2 - eBay (item 390188497169 end time May-27-10 11:06:03 PDT)

There are several Ebay sellers with similar offerings. Look for similar pictures.
