huangyong 0 Report post Posted June 27, 2006 hello DIY friends, need to ask you guys, especially those experience ones, what is the major difference in term of sound quality between the 2. There're many types of IC buffer out there, more popular ones are BUF643, HA5002, While discrete buffer, we have Diamond buffer, Class A, AB, B buffer, and MOSFET buffer. so please tell me whay have you used and tell me the sound quality. Thanks. Share this post Link to post Share on other sites

thedoctor 0 Report post Posted June 29, 2006 i particularly like the Discreet Diamond Buffer. don't matter if it's operating in Class A or AB, but surely beats the BUF634 in transparency and speed. the BUF634 sounds veiled. even a simplified Diamond Buffer or the Push-Pull Discreet Buffer sounds better than a BUF634. yet i've never tried the Intersil nor the Elantec buffers, but did a quick comparison between a simplified Diamond Buffer against the BUF634 and the DB is the clear winner. never used a BUF634 ever since. tho for simplicity, a BUF634 might be easier to implement/use.

heady 0 Report post Posted May 14, 2008 Hi Peranders, Fancy meeting you here in our humble forum. Thanks for the tip. Any comments regarding the sonics of this buffer? Regards Share this post Link to post Share on other sites
Guest peranders Report post Posted May 14, 2008 (edited) Not yet I'm afraid but I'm real glad that I know have a second source to BUF634 SMD since it's impossible to get hold of. I have BUF634 in my QRV04 headphone amp and it's not so good to sell pcb's which require parts that you can't buy. Edited May 14, 2008 by peranders Share this post Link to post Share on other sites

Thanks. For the sake of those still interested, I think a discrete diamond buffer is a better solution. Chips like the BUF643 are extremely hard to come by and even farnell doesn't have stock on their US/UK sites.. if I recall right. What's more, the discrete "monofied" Jung diamond buffer uses very common transistors and diodes that you can easily source in SLT within 5 minutes. If you google for "sijosae monofied diamond buffer", you should be able to find a link to a headwize or headfi thread that has the layout and schematic. The layout is supposed to be pin-compatible with the BUF634, so it makes it very easy to implement into any circuit that requires such a buffer. Share this post Link to post Share on other sites

Guest peranders Report post Posted June 2, 2009 (edited) What do you think of my new diamond buffer? It looks nice and works good .... if two patches are made. Parts are on both sides as you can see and the board has four layers. The boards are rather small also, compare with my finger.

That's quite a load of SMD transistors you got there. For 2 channels? Share this post Link to post Share on other sites
